Maybe this can help some people.

Disable menu animations

To disable menu animations (sliding in/out) and speed up performance of the UI a bit:

HKLM\SYSTEM\GWE\Menu\AniType = 0 (DWORD decimal)

To change it back to the default:

HKLM\SYSTEM\GWE\Menu\AniType = 6 (DWORD decimal)

Disable window animations

To disable window animations (minimizing/maximizing) and speed up performance of the UI a bit:

HKLM\SYSTEM\GWE\Animate = 0 (DWORD decimal)

And to switch them back on:

To change it back to the default:

HKLM\SYSTEM\GDI\GLYPHCACHE\limit = 8192 (DWORD decimal)

You can set the value to pretty much anything you like

Enable FileSystem cache

To enable the FileSystem cache, speeding up overall performance at the risk of the cache not being written on a sudden reset:

HKLM\System\StorageManager\FATFS\EnableCache = 1 (DWORD decimal)

To disable again:

HKLM\System\StorageManager\FATFS\EnableCache = 0 (DWORD decimal)

Note that by default, the cache size is zero, and you will see no effect. See "Increase FileSystem cache" to incease the cache size

Increase FileSystem cache

To increase the file system cache:

HKLM\System\StorageManager\FATFS\CacheSize = 4096 (DWORD decimal)

To return the file system cache to zero:

HKLM\System\StorageManager\FATFS\CacheSize = 0 (DWORD decimal)

You can set the value to pretty much anything you like

Increase FileSystem filter cache

To enable the file system filter cache, speeding up overall performance with file mangement:

HKLM\System\StorageManager\Filters\fsreplxfilt\ReplStoreCacheSize = 4096 (DWORD decimal)

To return the file system filter cache to zero:

HKLM\System\StorageManager\Filters\fsreplxfilt\ReplStoreCacheSize = 0 (DWORD decimal)

You can set the value to pretty much anything you like

Change the thickness of scrollbars

To change the thickness of the scrollbars at the right/bottom of documents larger than the screen, adjust...

For the horizontal (bottom) scrollbar:

HKLM\System\GWE\cyHScr = 9 (DWORD decimal)

For the vertical (right) scrollbar:

HKLM\System\GWE\cxVScr = 9 (DWORD decimal)

The default thickness is 13. You can set the value to pretty much anything you like

Change the length of scrollbar arrow buttons

To go with changing the thickness of the scrollbars, you may wish to change the length of the scrollbar arrow buttons...

For the horizontal (bottom) scrollbar arrows:

HKLM\System\GWE\cyVScr = 9 (DWORD decimal)

For the vertical (right) scrollbar:

HKLM\System\GWE\cxHScr = 9 (DWORD decimal)

The default length is 13. You can set the value to pretty much anything you like

Enable ClearType in Landscape mode

To enable ClearType in Landscape mode:

HKLM\System\GDI\ClearTypeSettings\OffOnRotation = 0 (DWORD decimal)

To disable:

HKLM\System\GDI\ClearTypeSettings\OffOnRotation = 1 (DWORD decimal)

Note that your PocketPC screen's LCD red/green/blue ordering required for proper ClearType display is only correct for Portrait display. You may or may not prefer to leave ClearType in Landscape mode disabled

Add a 'Disconnect' button (and Timer) to the Connection List for GPRS

To add a Disconnect button:

HKLM\ControlPanel\Phone\Flags2 = 8 (DWORD decimal)

To add a Disconnect button and a timer display showing how long GRPS is in use for the session:

HKLM\ControlPanel\Phone\Flags2 = 16 (DWORD decimal)

To disable both the Disconnect button and the timer:

HKLM\ControlPanel\Phone\Flags2 = 0 (DWORD decimal)

Change the 'user agent' identification of Pocket Internet Explorer

To change the 'user agent' identification of Pocket Internet Explorer, several fields need to be adjusted. The example shows how to identify as Internet Explorer 6 - desktop version

The standard compliance 'user-agent' string:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\(Default) = "Mozilla/4.0" (REG_SZ string, no quotes)

Defaults to "Mozilla/2.0" The application/version string:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Version = "MSIE 6.0" (REG_SZ string, no quotes)

Defaults to "MSIE 4.01" The host operating system string:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Platform = "Windows NT 5.0" (REG_SZ string, no quotes)

Defaults to "Windows CE" Please note that if you change the Platform string, PDA-friendly sites may stop sending you PDA-friendly content automatically. Leave this string set to "Windows CE" unless a site absolutely refuses to work, or you want the site to feed you its normal content.

Change the location of 'Temporary Internet Files'

When browsing the web, pages and images are saved in the 'Temporary Internet Files' location. You can change this location to, for example, your Storage Card:

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Cache = "\Storage Card\cacheie" (REG_SZ string, no quotes)

To return to the original location:

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Cache = "\Windows\Profiles\guest\Temporary Internet Files" (REG_SZ string, no quotes)

Change the display of the clock in the taskbar

The clock in the taskbar can be changed to show not only the time, but also the date, or just the date, or nothing at all.

To show nothing:

HKLM\Software\Microsoft\Shell\TBOpt = 0 (DWORD decimal)

To show just the clock:

HKLM\Software\Microsoft\Shell\TBOpt = 1 (DWORD decimal)

To show just the date:

HKLM\Software\Microsoft\Shell\TBOpt = 2 (DWORD decimal)

To show both the date and the clock:

HKLM\Software\Microsoft\Shell\TBOpt = 3 (DWORD decimal)

Note 1: If you switch to the Analog clock display, the date will remain visible -through- the Analog clock

Note 2: Setting the clock to show 'nothing' will still keep the reserved space, showing the taskbar background, and obscure any icons that will shift to the right.

Note 3: Your date may get obscured by the space reserved for the OK/Close button in the top-right. You can fix this my adding spaces at the end of your 'Short Date Format'. See also the tweak on 'Change the Short Date Format'

Change the Short Date Format

Applications may call upon the system to provide a 'short date format'. One such application is the Date/Time display in the taskbar, if set to show the date. To change the Short Date Format to show "Mon/2" (example):

HKLM\nls\overrides\SSDte = "ddd/d " (REG_SZ string, no quotes)

Note 1: For more information on date/time formatting strings, see: http://msdn.microsoft.com/library/d...vbenlr98/html/vafmtuserdefineddateformats.asp

Note 2: All applications using the short date format will be affected by this change. Choose wisely

Disable the security warning when installing non-certified application

To disable the security warning when installing a non-certfied application, set:

HKLM\Security\Policies\Policies\0000101a = 1 (DWORD decimal)

To restore the warnings:

HKLM\Security\Policies\Policies\0000101a = 0 (DWORD decimal)

Note that this makes it easier for any malware to install itself

Change the application launched by Today screen Soft Keys

To change the application launched by the Today screen Left soft key:

HKCU\Software\Microsoft\Today\Keys\112\Open = "\Windows\Calendar.exe" (REG_SZ string, including quotes)

To change the title of the Left soft key:

HKCU\Software\Microsoft\Today\Keys\112\(Default) = "Calendar" (REG_SZ string, no quotes)

To change the application launched by the Today screen Right soft key:

HKCU\Software\Microsoft\Today\Keys\113\Open = "\Windows\Start Menu\Programs\Contacts.lnk" (REG_SZ string, including quotes)

To change the title of the Right soft key:

HKCU\Software\Microsoft\Today\Keys\113\(Default) = "Contacts" (REG_SZ string, no quotes)

Note that 113 normally doesn't exist by default, and probably needs to be created

Also note that there is at least 1 application that allows you to set these through a GUI, developed by FdcSoft called SoftKeyAppletEx

Disable 3gp (video) size limit

To disable the 3gp (video recording format) size limit:

HKLM\SOFTWARE\HTC\camera\AppDefSettings\P3\EnableLimit = 0 (DWORD decimal)

To re-enable:

HKLM\SOFTWARE\HTC\camera\AppDefSettings\P3\EnableLimit = 1 (DWORD decimal)

Add GPS settings icon

If you have a GPS device, you can add a GPS settings icon to your Start > Settings menu using:

HKLM\ControlPanel\GPS Settings\Group = 2 (DWORD decimal)

HKLM\ControlPanel\GPS Settings\redirect <-- delete, or rename, this value

Note that '2' stands for the Connections tab, '1' is System and '0' would be Personal

Note also that this has reportedly disabled one person's USB connectivity. To restore, set "GPS Program Port = None", "GPS Connection Port = None", "Automatic GPS Management = on"

Add Lunar Calendar mode to Calendar

You can add a Lunar Calendar mode to the Calendar view, showing a 'Month' view with the Lunar months/days.

HKLM\Software\Microsoft\Calendar\ShowLunarCalendar = 1 (DWORD decimal)

And to disable again:

HKLM\Software\Microsoft\Calendar\ShowLunarCalendar = 0 (DWORD decimal)

Change location of ringtones

You can change the location where WM5 will look for ringtones by adjusting the following key (example given is for ringtones placed on the Storage Card root folder)

HKCU\ControlPanel\Sound\Categories\Ring\Directory = "\Storage Card\" (REG_SZ string, no quotes)

The default location may be "\Windows\" or "\Windows\Rings\" depending on your Device provider

Change slide-out keyboard layout

If you have a Device from one country, but would like to use the keyboard layout of another, you can change the keyboard's language setting to do so...

For US layout (QWERTY):

HKCU\ControlPanel\Keybd\Locale = 1033 (DWORD decimal)

For German layout (QWERTZ):

HKCU\ControlPanel\Keybd\Locale = 1031 (DWORD decimal)

For French layout (AZERTY):

HKCU\ControlPanel\Keybd\Locale = 1036 (DWORD decimal)

For other codes, see: http://www.microsoft.com/globaldev/reference/winxp/xp-lcid.mspx

Show Edge network indicator instead of GPRS

If your network provider supports the Edge network (and your device does as well), you can use the following to show a little 'E' icon instead of 'G' icon when connected to an Edge network:

HKLM\Drivers\BuiltIn\RIL\EnableDifferGprsEdgeIcon = 1 (DWORD decimal)

To disable again:

HKLM\Drivers\BuiltIn\RIL\EnableDifferGprsEdgeIcon = 0 (DWORD decimal)

Note that your device -and- your network operator need to support Edge, otherwise you won't see it. Also note that if you connect to GPRS, you will still see the 'G' icon.

Make reminders show only once

By default, reminders will keep bugging you for 2 minutes. You can change this to zero minutes by adjusting this value:

HKCU\ControlPanel\Notifications\Reminders\AutoSnooze\AutoSnoozeMins = 0 (DWORD decimanl)

Note that you can set this to any value you like. Alternative to setting this value to zero is to delete the '?AutoSnooze' key altogether

Remove operator skin from Phone app

If your device's Phone app is skinned, you can remove by setting:

HKLM\Security\Phone\Skin\Enabled = 0 (DWORD decimal)

Similarly, you can restore it with:

HKLM\Security\Phone\Skin\Enabled = 1 (DWORD decimal)

En/Disable receiving of files over BlueTooth/IrDA

If you want to prevent receiving files over BlueTooth or IrDA, you can set the following value:

HKLM\Software\Microsoft\Obex\IsEnabled = 0 (DWORD decimal)

And to (re-)enable:

HKLM\Software\Microsoft\Obex\IsEnabled = 1 (DWORD decimal)

GPRS always on

If you want your GPRS (or EDGE) connection to always be on, set the following:

HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\|gprs connection name|\AlwaysOn = 1 (DWORD decimal)

And to turn it off:

HKLM\Comm\ConnMgr\Providers\{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\|gprs connection name|\AlwaysOn = 0 (DWORD decimal)

Note that |gprs connection name| will depend on the name you've given your GPRS connection

Hide/Show Screen orientation icon

If you wish to hide the Screen orientation icon, shown in the task bar on some devices, you can set:

HKLM\System\GDI\Rotation\HideOrientationUI = 1 (DWORD decimal)

And to show it again:

HKLM\System\GDI\Rotation\HideOrientationUI = 0 (DWORD decimal)

If this doesn't work, you can try:

HKLM\Services\screenrotate = 0 (DWORD decimal)

And to show it again:

HKLM\Services\screenrotate = 1 (DWORD decimal)

Note that this icon and its feature may not be available on your device at all.

Hide/Show battery indicator in Task bar

If you wish to hide the battery indicator in the task bar on some devices, you can set:

HKLM\Services\Power\ShowIcon = 0 (DWORD decimal)

And to show:

HKLM\Services\Power\ShowIcon = 1 (DWORD decimal)

Note that this icon and its feature may not be available on your device at all. For example, the HTC Wizard regularly ships with a battery indicator in the Tray instead, governed by "Windows\Startup\Init_Tray.exe"._

_Note also that this reportedly does not work on AKU2 ROMs to remove the new battery indicator

Show slide-out keyboard caps/dot icon next to SIP

If your device contains a file called "capnotify.exe", try running it (most devices that have it will already have it in the Windows\StartUp\ folder), and setting the following value to get a visual presentation of whether you are in caps or dot (alternate key function) mode:

HKCU\ControlPanel\Keybd\EnableIndicator = 1

Please note that if your device has no external keyboard with caps/dot mode, you won't gain anything from this tweak

Please also note that the application "?CapNotify.exe" must be running (normally found in \Windows\?StartUp\ already) for this to work

Change ringtone/vibrate/LED flash characteristics

If you would like more control over how your device rings/vibrates/flashes its LEDs on events, you can can change the Script values of these events. For example, for an incoming call performing 'activate device, play ringtone, wait 3 seconds, repeat':

HKCU\ControlPanel\Sounds\RingTone0\Script = "apw3r" (REG_SZ string, no quotes)

For performing 'active device, set volume to 33%, play ringtone, set volume to 67%, play ringtone, set volume to 100%, play ringtone (no repeat)':

HKCU\ControlPanel\Sounds\RingTone0\Script = "ac33pc67pc100p" (REG_SZ string, no quotes)

The following are the full codes available to you. Please note that all the codes are executed simultaneously except after a ringtone play / wait code. E.g. 'v1p' will vibrate and play at the same time, while vibrating for 1 second. But 'pv1' will play the ringtone through all the way first, then start vibrating for 1 second.

a = activate device

cN = set volume to N in percentage max volume

fN = flash notification LED for N seconds

p = play ringtone. Note that this will play the ringtone all the way through before continuing with the next code.

r = repeat. Note that this should be the last code in your Script string, if used at all.

vN = vibrate for N seconds

wN = wait for N seconds. Note that the device will wait this long before continuing with the next code.

Change the keyboard backlight duration

To change the duration of the keyboard backlight, you can set (example is 30 seconds):

HKCU\ControlPanel\Backlight\QKeyLedTimeout = 30 (DWORD decimal)

Please note that this may not work on some devices. One such notable exception is the HTC Wizard.

Disable the SMS Sent notification

If you're tired of the "Message Sent" notification after sending an SMS/text message, you can disable them:

HKLM\Software\Microsoft\Inbox\Settings\SMSNoSentMsg = 1 (DWORD decimal)

And to re-enable:

HKLM\Software\Microsoft\Inbox\Settings\SMSNoSentMsg = 0 (DWORD decimal)

Please note that the 'Settings' key may not exist in your device, and thus may have to be created first.

Change the SMS Sent notification text

If you just want the "Message Sent" notification to read something different, adjust the following:

HKLM\Software\Microsoft\Inbox\Svc\SMS\MessageSent = "Message Sent" (REG_SZ string, no quotes)

Always require SMS Delivery notification

If you always want an SMS Delivery notification (see note below!), and are tired of ticking the 'Request message delivery notification' checkbox, set:

HKCU\Software\Microsoft\Inbox\Settings\SMSDeliveryNotify = 1 (DWORD decimal)

To disable again:

HKCU\Software\Microsoft\Inbox\Settings\SMSDeliveryNotify = 0 (DWORD decimal)

Note 1: Delivery notifications will depend on your and the recipient's operator network capabilities! Note 2: You can still override this with the regular checkbox.

Set default SIP

The default SIP on practically every device is the Keyboard. You may prefer entry with a different SIP. If so, you can set this to be the default SIP through:

HKCU\ControlPanel\SIP\DefaultIM = |SIP ClassID|

The |SIP ClassID| will depend on the SIP's ClassID, which may vary per-device. You can find the correct ClassID by searching for "IsSIPInputMethod" in HKCR, then going to the top key and checking the name of the SIP that's in the (Default) value.

Please note that this doesn't work with all SIPs. Transcriber/Calligrapher are two examples of this.

You can, however, set Transcriber as the default SIP by starting Transcriber.exe on startup. (This should be moved to, or added to, non-registry Tweaks page)

WARNING: Do not assume that the below ClassIDs would be -as found- on your device! Setting it to a non-existant SIP may prevent your device from booting up!

The following are some of the ClassIDs typically found:

Typical pre-installed:

{4345EA53-B8A5-4E24-A14A-F7C34DD78077} = WordLogic

Add/remove items from the SIP list

If you have a few items in your SIP list which you don't use, they can be removed from the list by setting the IsSIPInputMethod for each item you want removed. To remove the SIP from the list, replace the $SIP_CLSID$ in the example below with a CLSID from the Set default SIP tweak.:

HKEY_CLASSES_ROOT\CLSID\$SIP_CLSID$\IsSIPInputMethod\(Default) = 0 (DWORD decimal)

To add it back to the list:

HKEY_CLASSES_ROOT\CLSID\$SIP_CLSID$\IsSIPInputMethod\(Default) = 1 (DWORD decimal)

Put custom text on bottom-right of Today screen

You can set some piece of text on the bottom-right of the Today Screen by setting the following key:

HKLM\Software\Microsoft\Shell\DeviceBeta\Today = "Hello World" (REG_SZ string, no quotes)

Please note that this text won't take up Today item text. It will be obscured by Today items.

Navigate PIE up/down with the four-way pad

By default, PIE uses the four-way pad's up/down buttons to jump between hyperlinks and form fields. You can set it up to page up/down instead by setting:

\HKLM\Software\Microsoft\Internet Explorer\Navigation\4-Way Nav = 0 (DWORD decimal)

And to re-enable hyperlink/form field navigation:

\HKLM\Software\Microsoft\Internet Explorer\Navigation\4-Way Nav = 1 (DWORD decimal)

Note that you may still jump between links using Tab and Shift-Tab if your Device has a built-in hardware keyboard.

Navigate PIE up/down with any key

You can change the keys used by IE for page up/page down browsing by creating keys linked to these controls:

Page Up:

HKLM\Software\Microsoft\Internet Explorer\KeyMaps\|key code| = 1 (DWORD decimal)

Page Down

HKLM\Software\Microsoft\Internet Explorer\KeyMaps\|key code| = 2 (DWORD decimal)

Where |key code| is the code of the key pressed. For example, if your Device has a phone pad on the front, you may prefer to use the '2' key (keycode 50) for page up, and the '8' key (keycode 56) for page down, leaving the four-way pad to browse links:

HKLM\Software\Microsoft\Internet Explorer\KeyMaps\50 = 1 (DWORD decimal)

HKLM\Software\Microsoft\Internet Explorer\KeyMaps\56 = 2 (DWORD decimal)

Disable charging over USB

If your device can charge over USB, you can probably disable this feature by setting:

HKLM\Drivers\BuiltIn\usbfndrv\EnableUsbCharging = 0 (DWORD decimal)

And to re-enable:

HKLM\Drivers\BuiltIn\usbfndrv\EnableUsbCharging = 1 (DWORD decimal)

Show Calendar event text in Week View

If you wish to see a Calendar event's text in the Week View, set the following:

HKCU\Software\Microsoft\Calendar\ShowTextInWeekView = 1 (DWORD decimal)

To disable it again:

HKCU\Software\Microsoft\Calendar\ShowTextInWeekView = 0 (DWORD decimal)

Please note that your event must have long enough a duration to show the event text, and the week view (with its narrow columns) truncates long words easily

Also note that the key "Calendar" may not exist - just create it if it doesn't

Change Calendar 'working days'

If you wish to change the 'working days' in the calendar, adjust the following:

For a Mon-Fri workweek (default):

HKLM\Software\Microsoft\Calendar\ActiveTimes\ActiveTimes = 2210003E (DWORD hexadecimal)

For a Mon-Sat workweek:

HKLM\Software\Microsoft\Calendar\ActiveTimes\ActiveTimes = 2210007E (DWORD hexadecimal)

For a Tue-Thu workweek:

HKLM\Software\Microsoft\Calendar\ActiveTimes\ActiveTimes = 22100016 (DWORD hexadecimal)

Here's how this works. When editing the value, switch to "Binary" mode. For the default Mon-Fri, you should see:

100010000100000000000000111110

The last 7 numbers are what we're interested in. They stand for the days of the week, in reverse order: Saturday, Friday, Thursday, Wednesday, Tuesday, Monday, Sunday. When the number is "1", it is a working day. If it is "0", it's not a working day. So to look at the above examples again:

Days : SFTWTMS

Mon-Fri: 0111110

Mon-Sat: 1111110

Tue-Thu: 0011100

Using the above, you should be able to set the working days to whatever you'd like.

Note that this value also adjusts the working HOURS. The examples here all use the default 8am-5pm workday. See the "Change Calendar 'working hours'" tweak to modify this.

Note that the ActiveTimes key and value may not exist. Simply create them first.

Change Calendar 'working hours'

If you wish to change the 'working hours' in the calendar, adjust the following:

For 8am-5pm (default):

HKLM\Software\Microsoft\Calendar\ActiveTimes\ActiveTimes = 2210003E (DWORD hexadecimal)

For 9am-5pm:

HKLM\Software\Microsoft\Calendar\ActiveTimes\ActiveTimes = 2212003E (DWORD hexadecimal)

For 2pm-10pm:

HKLM\Software\Microsoft\Calendar\ActiveTimes\ActiveTimes = 2C1C003E (DWORD hexadecimal)

Here's how this works.

The first 2 characters define the ending hour as a count of half hours since midnight, in hexadecimal. So for midnight, it would be 0 half hours in hexadecimal = 0. 5pm is 17 hours, or 34 half hours. 34 in hexadecimal is 22. 10pm is 22 hours, or 44 half hours. 44 in hexadecimal is 2C. You can use a calculator capable of hexadecimal conversions to get the hexadecimal number.

Similarly, the next 2 characters define the starting hour as a count of half hours since midnight, in hexadecimal. So for 8am.. 16 half hours, 16 in hexadecimal is 10. 9am = 18 half hours = 12. 14h = 28hh = 1C.

Using the above, you should be able to se the working hours to whatever you'd line.

Note that this value also adjusts the working DAYS. The examples here all use the default Mon-Fri workweek. See the "Change Calendar 'working days'" tweak to modify this.

Note that the ActiveTimes key and value may not exist. Simply create them first.

Note that you cannot set the End time earlier than the Start time, for obvious reasons

Note that you cannot set a Midnight end time. The best you can do is 11.30pm (2F)

Show 'busy status' in Calendar Agenda View

To show the "Free"/"Tentative"/"Out of office" states in the Agenda View, set:

HKLM\Software\Microsoft\Calendar\ShowBusyInDescription = 1 (DWORD decimal)

To hide it again:

HKLM\Software\Microsoft\Calendar\ShowBusyInDescription = 0 (DWORD decimal)

Note that this only appears to affect the 'Agenda' view. No other views, and not the Today Screen item.

Make WM5 ask where to install a program (1)

If you wish to be able to specify whether to install a program on WM5's Main storage, or your Storage Card, regardless of installer setting set:

HKLM\Software\apps\Microsoft Application Installer\fAskDest = 1 (DWORD decimal)

To disable again:

HKLM\Software\apps\Microsoft Application Installer\fAskDest = 0 (DWORD decimal)

Please note that many applications do not support being installed on the Storage Card and may behave unpredictably, including crashing

Make WM5 ask where to install a program (2)

An alternative method of making WM5 ask where to install a program is by adding the "/askdest" option to the Windows CE loader:

HKCR\cabfile\Shell\open\command = 'wceload.exe "%1" /askdest' (REG_SZ string, no quotes)

Make WM5 keep CAB files around after installing (1)

If you wish to keep the original .CAB file around after installing the application, set:

HKLM\Software\apps\Microsoft Application Installer\nDynamicDelete = 0 (DWORD decimal)

Or to restore to the default:

HKLM\Software\apps\Microsoft Application Installer\nDynamicDelete = 2 (DWORD decimal)

Make WM5 keep CAB files around after installing (2)

An alternative method of making WM5 keep the original .CAB file around after installing the application is by adding the "/nodelete" option to the Windows CE loader:

HKCR\cabfile\Shell\open\command = 'wceload.exe "%1" /nodelete' (REG_SZ string, no quotes)

Make WM5 prompt before overwriting an existing installation

If you wish to make WM5 prompt you before overwriting an existing installation, set:

HKLM\Software\apps\Microsoft Application Installer\fAskOptions = 1 (DWORD decimal)

To disable again:

HKLM\Software\apps\Microsoft Application Installer\fAskOptions = 0 (DWORD decimal)

Show Tomorrow's Appointments on Calendar Today item

If you wish to see tomorrow's Appointments on the Calendar Today item, set:

If you wish to see today's All Day event as well:

HKLM\Software\Microsoft\Today\Items\Calendar\Flags = 5 (DWORD decimal)

If you do not wish to see today's All Day event:

HKLM\Software\Microsoft\Today\Items\Calendar\Flags = 4 (DWORD decimal)

Other values (attainable through the "Options..." dialog for the Calendar Today item just as well):

0 = Show Upcoming Appointments

1 = Show Upcoming Appointments and today's "All Day" event

2 = Show Next Appointment

3 = Show Next Appointment and today's "All Day" event

It works out to the following binary structure:

Default Behavior: Show Upcoming Appointments

000

||'- Show "All Day" events (doesn't show tomorrow's "All Day" events)

|'- Show Next Appointment

'- Show Tomorrow's Appointments

Low Battery warning

By default, a PPC will sound a warning sound when the battery is running low (10%, fixed value), but there's no way to disable or change the notification. To enable this, so that it is visible in the "Sounds & Notifications" control panel, set:

HKCU\ControlPanel\Notifications\{A877D663-239C-47a7-9304-0D347F580408}\Default = "Low battery warning" (REG_SZ string, no quotes)

Note that the string used can be whatever you like it to be

Replace Left/Right-handed landscape option with single Landscape option

If for some reason you wish to disable the display of left-handed/right-handed in Start > Settings > |System| > Screen, and replace it with a single "Landscape" option, set:

HKLM\System\GDI\Rotation\LandscapeFixed = 1 (DWORD decimal)

To restore, set:

HKLM\System\GDI\Rotation\LandscapeFixed = 0 (DWORD decimal)

Please note that when you set it fixed, you can no longer switch between left-handed/right-handed through Start > Settings > |System| > Screen, only between Portrait and Landscape. If you wish to change the orientation, use an external application or see the Landscape Orientation Tweak.

Change Landscape Orientation

By default, the Landscape Orientation (i.e. what way the screen is rotated when put into Landscape mode) is set either by the manufacturer or through the Screen control panel applet. If you have disabled the left-handed/right-handed orientation (see "Replace Left/Right-handed landscape option with single Landscape option" tweak), you can still change the Landscape orientation through the registry:

Right-handed:

HKLM\System\GDI\Rotation\LandscapeMode = 1 (DWORD decimal)

Left-handed:

HKLM\System\GDI\Rotation\LandscapeMode = 4 (DWORD decimal)

Please note that a soft reset is required for this to take effect - an external screen rotation utility is recommended over this tweak

Please also note that some devices which change orientation automatically based on e.g. keyboard slide-out may have the orientation hard-wired, and switch to e.g. Left-handed even if you set it to go to Right-handed

AKU2 ROMs tweaks

These are tweaks that have been confirmed to work on AKU2 ROMs, and confirmed not to work on earlier ROMs

Show Wireless Today item

By just adding following keys to the registry will get you a nice 'wireless' today item that show Network name/status, WiFi name/status as well as Bluetooth status. Confirmed to work on AKU2 ROMs

[HKLM\Software\Microsoft\Today\Items\"Wireless"]

"DLL"="netui.dll"

"Order"=dword:00000000

"Enabled"=dword:00000001

"Type"=dword:00000004

Add time sync page to Phone Settings

To add a time sync page to your Phone Settings (Start > Settings > Phone > Options > Time Zones) , set the following:

HKLM\SOFTWARE\OEM\PhoneSetting\ShowTimeZonesPage = 1 (DWORD decimal)

And to remove again:

HKLM\SOFTWARE\OEM\PhoneSetting\ShowTimeZonesPage = 0 (DWORD decimal)

AKU2.2 ROMs tweaks

These are tweaks that have been confirmed to work on AKU2.2 ROMs, and confirmed not to work on earlier ROMs

Restore Clock on Taskbar when on Today Screen

The AKU2 update brought with them a, arguably lame, battery icon which replaced the Clock. Although the clock can be restored when running applications, it is permanently removed when on the Today Screen. Microsoft have addressed users' concern over this in the AKU2.2 update. You can restore the clock entire by setting the following:

HKLM\Software\Microsoft\Shell\ShowTitleBarClock = 1 (DWORD decimal)

Tweaks that can be done through the normal user interface

These are tweaks that can be done through the normal user interface, and thus don't require tweaking the registry in any way, shape or form

Default SMS Delivery Notifications to on

This tweak can be set through: Start > Programs > Messaging*, Menu > Tools > Options... > Text Messages* > [x] Request delivery notifications

To always have SMS Delivery Notifications enabled:

HKCU\Software\Microsoft\Inbox\Settings\SMSDeliveryNotify = 1 (DWORD decimal)

To disable them (can still enable per-SMS in SMS settings):

HKCU\Software\Microsoft\Inbox\Settings\SMSDeliveryNotify = 0 (DWORD decimal)

Note that SMS Delivery Notifications are a network provider option, and the recipient may refuse them to be sent out

Show the clock in all applications

This tweak can be set through: Start > Settings > |System| > Clock & Alarms* > |More| > [x] Display the clock on the title bar in all programs

To show the clock on the titlebar in all applications:

HKLM\Software\Microsoft\Shell\TaskBar\LimitedClock = 0 (DWORD decimal)

To hide it again (only visible on Today Screen):

HKLM\Software\Microsoft\Shell\TaskBar\LimitedClock = 1 (DWORD decimal)

Note that on AKU2.0 ROMs, it is not possible to show the clock on the taskbar when on the Today Screen at all. This was adjusted by Microsoft for AKU2.2. Pre-AKU2.0 ROMs do not suffer from this deficiency.

Tweaks that work in WM2003, but do not work on WM5

Please put depricated or debunked tweaks here, so they are not reinstated by some other well-meaning person later. Of course, please provide corroberation of your change.

Enable Realtime Memory Defragmenting (or something.)

There isn't any concise description of this tweak, but it appears to free up some memory if nothing else.

HKCU\Software\Microsoft\Shell\NeverDorkMemory

Note that you should only create the key; this is not a value! See here: http://www.pocketpcthoughts.com/index.php?action=expand,47926
