Hey Guys -
We recently disabled System Restore on all ~700 Windows 7 workstations on our domain. After doing so, we noticed that when going to System Properties and viewing System Protection, System Restore would say "System Restore is disabled by your system administrator" however under Protection Settings, it would be set to "On."
We basically ignored this for a while, but just today found out that issues we have been experiencing for a couple of weeks now were due to systems creating up to thousands of snapshots which reported having the speed issue. Running Microsoft DevNodeClean fixed these snapshots, but we still aren't 100% sure what caused them. As it's only been about a month since System Restore was disabled, we believe it may have something to do with the above setting being disabled, but listed as "On."
We found registry keys which should fix the issue, but so far no GPOs other than the one we have set to disable System Restore.
Any Suggestions? Thanks!
Ben K.
UPDATE
Guess I should also mention the systems are Windows 7 SP1 x64 - Thanks :)
UPDATE 2
I found out that on a system where you manually disable System Restore, the string "RPSessionInterval" in the following key is set to "0"
"HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore"
On our systems - all of which have System Restore disabled via GPO - it's set to "1." Below's a screenshot of the key's settings from the same system as the screenshot above:
