Titolo: Punti di ripristino in WinME

Ciao a tutti
E' possibile cancellare eventuali punti di ripristino?
E win ne crea (quando necessario) fino a riempire lo spazio assegnatogli nel
menů file system o segue delle regole (mi spiego, esempio cancellando i
punti piů vecchi di, diciamo, due mesi)?
Ciao e grazie

MORE INFORMATION
What is System Restore?
System Restore is designed to automatically monitor and record changes made
to the core Windows system files and to the registry. System Restore can
then allow you to undo (or "roll back") a change that caused instability in
your system. This is accomplished by periodically recording a "Restore
Point" (or System CheckPoint) that gives you the ability to roll your system
back to the point in time when your computer was known to function properly.
System Restore is not intended to be an "uninstaller" or a backup program.
If Windows does not function properly after installing software or drivers,
you should use the Add/Remove Programs tool in Control Panel (or use the
program's uninstaller) to remove the software before using System Restore.
Monitored File Types
System Restore monitors most system files with .exe, .vxd, .dll, .com, and
.sys extensions. It does not monitor user-created files (for example, files
that have .txt, .doc, or .xls extensions), the My Documents folder,
Temporary Internet files (including the Internet Explorer History, Cookies,
or Favorites files), the Recycle Bin, or the Windows Swap (.swp) file.
How to Start and Use System Restore
To start System Restore, follow these steps:
Click Start, point to Programs, point to Accessories, point to System Tools,
and then click System Restore.
The first time you use System Restore, there are two options on the Welcome
page:
Restore my computer to an earlier time
Create a restore point
Click Restore my computer to an earlier time and click Next.
A calendar appears.
In the calendar, choose which Restore Point to roll your system back to.
Click Next.
You are prompted to close all applications before completing the Restore
process because the computer will restart.
Upon completion of the restart, a confirmation screen appears. Click OK to
continue using your computer.
The next time you start System Restore, you will see a third option, Undo my
last restoration. This is available in the event that the Restore Point you
rolled back to does not correct the original problem that you were having
and so you can easily get back to the point in time that you started
troubleshooting.
When Restore Points Are Created
Restore points are created under the following conditions:
Automatic System CheckPoints are created for every 10 hours of computer up
time but only after the computer has been idle for 2 minutes. If this
criterion is not met, then a System CheckPoint will be created once every 24
hours after the system has been idle for 2 minutes.
Restore points are created by Installer packages that use the new Microsoft
Software Installer (MSI) technology.
Restore points are created by Installer packages that use InstallShield 6.1
Pro and later.
Restore points are created when AutoUpdate (AU) installs an update package.
Restore points are created when you use System Restore to roll your system
back to a different Restore Point. However, if this is done in Safe Mode, a
Restore Point will not be created.
Restore points are created manually by using the System Restore interface.
The Restore Point and System CheckPoint files that are created under the
above conditions are stored in compressed (.cab) format and are located in
the _Restore folder (also known as the "Data Store") on the drive on which
Windows Millennium is installed. The Data Store cannot be moved or modified.
Each fixed disk on your computer will also contain a _Restore folder for
indexing and monitoring purposes and each of these folders will contain a
file called Srdiskid.dat.
When to Create and Use Manual Restore Points
Manual restore points can be created before installing device drivers or
software if you are uncertain how they will affect the overall performance
of Windows. If you are unable to use the program's uninstaller to remove the
software, you can roll back to the manual restore point that you created. To
create a manual Restore Point, follow these steps:
Click Create a restore point, and then click Next.
Enter the description of your Restore Point and then click Next to confirm
the creation.
Click OK or Home.
The Data Store
The size of the Data Store is determined by the size of the Windows drive
and is as follows:
The minimum size of the Data Store is 200 megabytes (MB). If your Windows
drive has fewer than 200 MB of free space after you install Windows
Millennium, System Restore is disabled by default and you will have to
manually enable System Restore after you have freed up sufficient disk
space. If System Restore is disabled due to the low disk notifier, System
Restore automatically re-enables itself after sufficient disk space is made
available.
On logical drives that are less than 4 gigabytes (GB), the maximum size of
the Data Store is 400 MB.
On logical drives that are 4 GB or larger, the Data Store is approximately
12 percent of the logical drive that Windows Millennium is installed on.
Once the Data Store reaches 90 percent of the allotted size, it begins to
"purge" older Restore Points on a first-in first-out (FIFO) basis until the
Data Store reaches 50 percent of its allotted size. The actual number of
Restore Points available after this purge occurs may vary, based on what
software was recently installed.
To manually adjust the size of the Data Store, follow these steps:
In Control Panel, click System.
Click the Performance tab.
Click the File System button.
On the Hard Disk tab, adjust the System Restore disk space use slider to the
preferred size.
IMPORTANT NOTE: Reducing the disk space used by System Restore may FIFO
existing Restore Points, so use caution when performing this action.
Recovering from a Failed Restore Operation
If your computer becomes non-bootable and System Restore was the last
operation performed, you can use the Emergency Boot Disk (EBD) to revert
your computer back to the state prior to the Restore operation. When you use
the EBD to boot your computer, you will see the following message:
System Restore detects that a restore was the last operation completed. It
is recommended you now revert the changes to your system made by System
Restore and restart before you proceed. If you choose not to revert these
changes, this option will no longer be available.
1)Revert the Restore changes made to my system.
2)Do not revert the Restore changes made to my system.
Enter a choice
If you select the first option, your computer reverts to the state prior to
the restore operation and you are prompted to restart the computer:
System Restore reverted the chances made by the last restore operation.
Remove all disks from the floppy disk drives and press CTRL+ALT+DELETE to
restart your computer.
Although it is not recommended, you can disable System Restore by following
these steps:
In Control Panel, click System.
Click the Performance tab.
Click the File System button.
Click the Troubleshooting tab.
Click the Disable System Restore check box.
Click OK, and then click Close.
Restart your computer when prompted.

Ti ringrazio per il tuo interessamento
Ho consultato anche altri post sul bel sito indicatomi, e sono risalito alla
directory _RESTORE, e dopo aver reso visibili i file nascosti di sistema, ho
"scoperto" dove stavano i 370MB di file sul ripristino.
Ora ciň che non capisco č quali file cancellare, visto che non sono
riconoscibili dal nome, ma al massimo dalla data, e non vorrei che, tra
l'altro, cancellandoli bloccassi qualcosa d'altro.
Cosa ne pensi?
Mi permetto di postare altri msg con una richiesta simile sul newsgroup per
avere altri pareri, nel frattempo.
Ti ringrazio molto
Caspa
