Transaction support within the specified resource manager is not started or was shut down due to an error

Question

Got the following error while trying to add, edit or delete a windows schedule task:

Transaction support within the specified resource manager is not 
started or was shut down due to an error.

Tried to reset transaction manager through fsutil (as suggested by a few people on answers.microsoft.com)

fsutil resource setautoreset true c:\

but it didn't work.

Also noticed that windows update was failing with an unknown error as well.

Answer 1

Manually clearing all the files from the following directory fixed the problem

C:\Windows\System32\config\TxR

I also reset the resource manager through fsutil before restart (not sure it was required or not)

fsutil resource setautoreset true c:\

Although I didn't try, but, its possible that the problem occurred because of some stuck NTFS Transaction, so probably you can also try cancelling all the zombie transactions using fsutil

First list the transactions using

fsutil transaction list

and then roolback any thing suspicious using

fsutil transaction rollback <GUID>
