When creating a System Restore point manually, I get a nondescript error message:
The restore point could not be created for the following reason: Access is denied. (0x80070005)
I've been troubleshooting for hours. I have...
- Uninstalled my virus scanner (Microsoft Security Essentials)
- Disabled System Restore and rebooted (to clear out all restore point files)
- Rebooted in safe modes
- Tried to find which file/folder might have access denied (no clues)
- Searched Event Logs
- Run SysInternals ProcMon
- Attempted to give "Full Control" security permissions recursively to "C:\System Volume Information" for SYSTEM, LOCAL_SERVICE, SERVICE, plus my user account.
No luck at all.
I eventually discovered Windows is able to create Restore Points automatically:
- Since I no longer had any restore points (due to troubleshooting) I decided to run Windows Backup(**)... Low and behold, a system restore point got created!
So it seems I have a workaround. Still, it would be great to get to the bottom of this.
These are the only system changes I can think of over the last few months. They seem like long-shots, but could they be relevant?
- From Microsoft Update, I installed and ran a "Disk Cleanup" plugin that clears out old Service Pack update stuff
- I'd previously granted "Full Control" security permissions recursively to "C:\System Volume Information" for my user account, to snoop around. Could I have overwritten some important permission?
(**) When I then asked Windows Backup to delete my backup, it said "Access is denied. (0x80070005)" Arrrgh! :-) Fortunately I can do this myself. But could this be another clue?
UPDATE: I also cannot revert to a restore point: same error given.
Workaround: restore after booting in Safe Mode (NB: cannot be undone)
