Two days ago when I was trying to create a Restore Point manually, my windows 7 PC welcomed me with the following error message.

“Transaction support within the specified file system resource manager is not started or was shutdown due to an error. (0x80071A91)”

Since my pc is always used to be in top condition the error was very much unexpected to me,. I tried to search “Microsoft help” but what I got is this “http://support.microsoft.com/kb/927748/en-us”. Microsoft help wasn’t really helpful.

After doing some research and a little bit of Googling I finally found the solution. Actually the “fsutil.exe” tool has an additional argument “resource”, which evidently controls FSRM {file system resource manager} behavior. So resetting the FSRM actually solved the Problem.

So if u see the Error (0x80071A91) on your vista or windows 7 PC then follow the following steps: =

  1. Click the ‘Start Button’ on your Desktop.
  2. Type “cmd” in the search field and open command prompt in Administrator mode {Right Click and select “Run as administrator”}. It you still have UAC enabled, it will ask you for permissions, click “OK”.
  3. Type “fsutil resource setautoreset true C:\”  {assuming that you have your OS on drive C }
  4. Reboot your computer.

If you follow these steps your problem will be solved.
