I am having a problem with System Restore on Windows 7 Home Premium 64-bit. I can make restore points easily, but if I try to go back to one, I get this:

System Restore did not complete successfully. Your computer's system files and settings were not changed.

Access is denied. (0x80070005)

You can try to run System Restore again and choose a different restore point. If you continue to see this error, you can try an advanced recovery method. For more information, see What is Recovery?

There are two buttons underneath that say "Run System Restore" and "Close." I tried to click "Run System Restore," but that gave me another error:

There was an unexpected error:

Catastrophic failure (0x8000FFFF)

Please close System Restore and try again.

The one button underneath says "OK." I have tried this multiple times and nothing seems to work. I have turned System Restore off, and then on, but after creating a new restore point, the result is the same. I do not have any restore points that I need right now, so I am just looking to the future. At all costs I would rather not re-install Windows. I also have a third party backup program which I use, but I would like to use System Restore as well.

Did you try to do it from Safe-Mode ? – Amirreza Nasiri Sep 4 '13 at 22:43
I attempted this from safe mode, but I received the same error messages. – j.m.g.r Sep 9 '13 at 20:01
I attempted to run "svc /scannow" from command prompt, and then in an elevated command prompt, and then in run, and then with quotes, and then without quotes, each time I recived the error "'scv' is not recognized as an internal or external command, operable program or batch file." – j.m.g.r Sep 9 '13 at 20:04
Try running chkdsk /f /r to fix any errors. – DominatorX Jul 12 at 23:30
@Ramhound I assume you mean sfc /scannow. – DominatorX Jul 13 at 0:58

If you have Norton Internet Security (NIS) or similar anti-malware, it could be interfering with the Restore. NIS has a "tamper protection" feature which prevents System Restore (because that could unload NIS). That tamper protection needs to be turned off to allow the Restore to work. For more see this

Thank you for your reply, although I do not have Norton Internet Security, I have Windows Defender, Avast! Free Antivirus, and Malwarebytes Anti-Malware. Would any of these programs cause the same problem? – j.m.g.r Sep 9 '13 at 20:06
I don't know if any of those packages have such a feature. If they do, they would have a way to turn it off in their interface (i.e. uninstall should not be necessary). You could check their documentation. – mgkrebbs Sep 10 '13 at 3:18
I've looked around in each of the user interfaces, and the command line interfaces, and it doesn't look like any of them have an option like that of Norton Internet Security. I have thought about just using the Windows "system image" feature. Theoretically, could I restore my computer to that state by booting into a system repair disc? That would be of extra benefit, because if my hard drive was formatted, I could restore even from that, if my assumption is correct. – j.m.g.r Sep 12 '13 at 1:51
