Windows 7: Corrupted Task Manager

24 Sep 2015   #1

Windows 7 Home Premium +SP1 64 bit
Corrupted Task Scheduler

The tasks are not being performed. When I open Task Scheduler I get error message that the Task is corrupted or has been tampered with. This happens for every one of the 50 plus tasks that are in the tree. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Schedule\TasksCache\Tree]

As one is dismissed with a click the next one comes up with the same message until every one has been dealt with. I believe this may relate to upgrade to Windows 10 and rollback to Windows 7. I never had the problem before then. I have tried going to the earliest system restore available with no success. Short of re-installing Windows 7 from disk and having to reload all my software is there any solution to this problem. Norton 360 tells me I have no virus problems. My contact with the net is relatively small anyway.

My other machine is 32 bit and the items in the tree are not the same so I cannot copy those across as a possible fix. In any case I do not believe the tasks themselves are corrupt. It seems to be a problem with Task Scheduler.

Has anyone else had this problem? Would appreciate any help with this issue

I am a little surprised to find no answer here. However, for the benefit of anybody else who is searching for an answer to this problem I have found one on CodePlex where there is an open source small programme by Dijjii
available to download that resolves the issues.

For the benefit of anyone else who is searching for an answer to this problem:
The CodePlex solution fixes most (sometimes all) of the issues. If some tasks are still corrupted, this thread has a link to Microsoft's tedious solution: My long list of Task Scheduler corrupt or tampered with tasks!!

This member had a few tasks that needed the manual fix.

Task Schedule err msg: corrupted task image
I don't use Task Scheduler at all and I've seen this err msg before, so I've never bothered to clean that up. But now I want to do that. The err messages are many, each one popping up with a different task name. But eventually the long string of popups end. You have to click the OK button...
