Windows 8 build 8102.101

Windows 8 build 8102.101 is the official Developer Preview and Milestone 3 build of Windows 8, which was released on 13 September 2011, the first day of the Microsoft Build 2011 conference.Microsoft. Microsoft Reimagines Windows, Presents Windows 8 Developer Preview, Microsoft News. 13 September 2011.Sinofsky, Steven. Welcome to Windows 8 – The Developer Preview, Building Windows 8. 13 September 2011. Attendees of the conference received an x64-based tablet made by Samsung with the build pre-installed.
When it was released, an "Install Fair" E-Mail was sent to users about it when it released.
The build was officially released in three variants, notably including a x64 release with pre-installed developer tools in addition to regular x86 and x64 compiles. It was only available in English (United States) localization, likely due to the fact that many locale-specific resources for the Metro user interface were hardcoded directly in the DLL files such as shsxs.dll and thus were not affected by MUI. A Simplified Chinese language pack was later leaked by Chinese website cnBeta on 20 September 2011, exactly one week after the build's public release.[图+下载Windows 8 开发者预览版中文包[更新x86/x64]], cnBeta. 20 September 2011. Archived from the original on 23 September 2011. An ARM compile is also known to exist, as some of its components have been discovered on the Microsoft Symbol Server.
It is notably the only available build to come with the Redpill feature set unlocked out-of-box via the official unlock procedure, therefore having the complete Windows 8 user interface enabled by default. It is also the first available build to come with the full set of pre-installed Metro applications, although the included application set mostly consists of sample applications only built to demonstrate various capabilities of the platform.

== Redpill ==
This is the first public release of Windows 8 to have all of the new Metro features working out-of-box. While the image that was distributed by Microsoft has the new shell enabled, it still utilizes the same internal mechanism of unlocking Metro features through Redpill as seen in earlier builds. A remnant from the Redpill application is present in this build in the form of a redpill.log file in the Windows\System32 directory, giving some insight to the functioning of the official Redpill unlocker.
The contents of the file are listed below:
As the build was intended to be distributed en masse, the Redpill edition installed in this build's OS image (RP01-PDC) is only applicable to the Developer Preview and Datacenter Server SKUs, and it will activate automatically whenever either base SKU is activated. Non-SKU-limited editions of Redpill also exist, labeled RP01 through RP05, though these require separate activation to be functional. The pre-installed Redpill product key, 6PB3F-HJWFK-X9YD4-8TB7Q-YQ2FB, is applicable to both RP01 and RP01-PDC.
Because of the similarities in the way of how features are locked between this build and some earlier builds, the files dropped by the relevant Redpill tool have been used to unlock Windows 8 shell features in several older builds including but not limited to 8056 (fbl_grfx_dev1), 7989, and 7927.
To showcase the abilities of the new Windows 8 user interface, the build includes a set of sample applications that take advantage of various existing Windows Runtime functions.
===Disabling Redpill===
Setting the value of RPEnabled in SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer to 0 within the HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE root keys will disable all Metro features, effectively un-redpilling the build and enabling a shell experience similar to earlier leaked builds of Windows 8 and by extension Windows 7, achieved after a full system restart. Special applications were created to suffice for this need.
==New features and changes==
===Desktop UI===
====Control Panel====
=====Devices and Printers=====
The Devices and Printers Control Panel applet no longer prompts the user to enable downloading additional Device Stage metadata over the Internet.
====Windows Extended theme====
A new "Windows Extended" theme has been added to help showcase multi-monitor support capabilities.
====Miscellaneous==== 
* All region-specific themes included as part of Windows 7, as well as Internet Explorer region-specific links for favorites and RSS feeds, have been removed from the operating system.
*A no-warranty disclaimer for Samsung Series 7 Slate tablet PCs has been added to the Contact Support page found within the Help and Support Center.
===Metro UI===
====Charms====
The Start charms menu's animation has been updated to fade into view when hovering over its respective hot-corner, rather than sliding from the bottom. The Connect charm was renamed to Devices and no longer prompts the user about the lack of compatible Send applications when attempting to project to other displays.
====Start screen====
The default Start screen layout has been updated to no longer include common Win32 desktop applications, and now only includes Internet Explorer, Windows Store, Windows Explorer, and the Immersive Control Panel applications as the default pinned tiles, in addition to the "Switch to Desktop" tile.
Semantic view mode on the Start screen has been temporarily disabled.
====Inbox applications====
Multiple inbox system applications, namely the Internet Explorer, Immersive Control Panel, Remote Desktop Connection, Windows Store, have had their pinned Start screen tiles redesigned and recolored to shades of light blue, yellow and orange, respectively.
Context menus in the tablet-optimized Internet Explorer 10 user interface have been resized to fit all possible options.
The Windows Store has been forcibly disabled in this build as the underlying platform was not yet ready for public use. A "coming soon" message is instead displayed to the user when launched, although all relevant code for the Windows Store is still present in the application.
====Boot UI redesigns====
The redesigned Windows Boot Manager and Windows Recovery Environment user interfaces are now enabled by default. This functionality is controlled by Boot Configuration Data (BCD) OS loader boolean variable BCDE_OSLOADER_TYPE_BOOT_MENU_POLICY (BOOTMENUPOLICY; 0x250000c2), which controls enablement of the new Windows 8 boot UI behavior. It is set to value 1 (Standard) in this build.
The redesigns may be turned off by setting the value of the aforementioned variable to 0 (Legacy).
====Miscellaneous====
Sizing adjustments towards Metro dialog modals have been implemented to allow more content to fit properly, and text in dialog modals are now colored properly when drawn in the desktop view.
===Miscellaneous=== 
*Third-party trusted root certificates for DigiCert Assured ID Root CA and GTE CyberTrust Global Root have been added to the system.
*The end-user license agreement has been updated for the public Developer Preview release.
==Bugs and quirks==
===Installation===
*Upgrades to this build have been disabled by default as it is intended to be a preview release; this behavior is controlled by the presence of an empty noupgrade.txt text document in the sources directory. It can be re-enabled by removing the binary from the installation media.
===Desktop Window Manager=== 
*Applications that make use of the DWM extended client area will only properly render translucency effects for 3/4ths of the visible area if Redpill is enabled.
*Switching to a High Contrast theme and then switching back to Aero or Aero Lite might result in a fully transparent taskbar. The navigation bar may also appear black.
* Running WindowsAnytimeUpgradeResults.exe with the Aero Lite theme applied will forcibly enable DWM blur effects.
