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)

The sheer fact you are adjusting permissions is a sign your Windows installation is corrupt. Have you tried restoring the original permissions to the folder you changed? –  Ramhound Nov 13 '13 at 14:17
How exactly did you grant yourself those permissions? What are the permissions currently on the System Volume Info partition? –  techie007 Nov 13 '13 at 14:29
Not sure what the original permissions were now. :-) I'm hoping/expecting that setting (SYSTEM, LOCAL_SERVICE, SERVICE, luke) recursively would be a superset of the defaults & what the system requires. –  Luke Usherwood Nov 13 '13 at 14:48
@LukeUsherwood - I would load up one of Microsoft's free virtual machines and check what the permissions should be. Even if you restore the original permissions there is no guarantee your previous changes don't do something else. –  Ramhound Nov 13 '13 at 14:49
