Regardless of *why* these System Restore points are being created,
perhaps the best way for you to deal with the situation is to turn SR
*on* for all partitions and use the "Settings" tab of the SR User
Interface to set the amount of disk space to use to the minimum (move
slider all the way to the left). By default, in XP, SR uses 12% of the
partition, which is too much space on today's large drives even if you
*want* to have SR running. If System Restore runs out of the storage
space that has been allocated towards its use, it will delete the oldest
restore point in order to create space for the new restore point.
System Restore actually creates restore points under at least 5
different circumstances:
1. scheduled restore points (system checkpoints) (approx every 24 hours)
2. before a restore to a restore point (so you can UNDO the restore)
3. before installing Windows updates received via AutoUpdate
4. before installing an app that uses a SR-compatible installer (e.g.
InstallShield).
5. manually created restore points
Turning SR off *should* not only disable the creation of system
checkpoints (which also relies on the Task Scheduler service), but also
should stop SR from checking for events 3 and 4. You can use
services.msc to see if the System Restore service is actually stopped
when you tell it to "Turn off System Restore on all drives."
It may be that the applications that you are installing do not rely on
SR being triggered by the installation but instead create a manual
restore point. I know that some antimalware apps (e.g., Spybot Search &
Destroy) can optionally create a restore point prior to deleting malware
that the app has identified. Perhaps the apps you are installing do the
same. In this case, your SR configuration settings are being bypassed.
You can delete SR points that are created by your app installations. Use
the user interface to turn SR on for each partition that has SR points
and then turn it off or use the Disk Cleanup tool (cleanmgr.exe) for
each partition and specify "remove all but the most recent restore
point" on the "More Options" tab.
In Vista and Win 7, SR relies on the "shadow copy" feature of NTFS and
thus can't monitor FAT32 partitions. In XP, SR works differently (see,
e.g.,
http://www.microsoft.com/middleeast/windowsvista/features/foreveryone/backup.mspx).
