Task image is corrupt or has been tampered with 0x80041321

Ok, I know this is an old post, but it seems people still hit this situation, myself included. I'd like to detail my experience before asking my question. I know this has to do with Windows Home Server, but that's just the symptom of the same underlying problem related to this thread.

Starting at the beginning, I was running Vista Ultimate 32-bit with Windows Home Server 2011. I (finally) got around to upgrading to Win 7 Ultimate 32-bit. After a couple of days of installing windows updates, I finally got to the point where the dust settled and wanted to get a backup using WHS. It turns out to my surprise that WHS thought my computer was offline. After figuring out that an update caused this, I used system restore to go back to a previous point in time. I had to do this several times due to so many updates being installed in such a short period, there weren't many restore points to choose from. Also, at 1 point, I was disconnected from the network and couldn't get to the Internet, WHS or any other home computer. It was a long process to selectively install a few updates at a time then check my network connectivity and create a system restore point. After it seemed like all the required updates were installed, WHS still thought my computer was offline.  I uninstalled the WHS connector software thinking a fresh install under the new Win 7 OS would do the trick however, it wouldn't install. When I started digging into the Event Viewer on both WHS and my computer, it pointed me to a log file on my computer that detailed the task related error message that brought me to this page.

The marked answer seemed overkill but other posts on this thread pointed to a security bulletin and update that caused the problem. I could no longer see any updates applied prior to my upgrade in order to attempt to remove the alleged culprit update. I had reservations about deleting all subkeys of the Schedule registry key but it seemed I had no alternative other than booting with the WHS client computer restore CD and doing a full restore back to Vista but I knew that was a step backward and I would have to go through this whole process again. Moving forward, I confirmed opening Task Scheduler resulted in 52 errors as it tried to open all the registered tasks. I closed Scheduler, backed up my registry and the System32\Tasks folder. I then deleted all registry subkeys under Schedule as noted in this thread as well as deleted all the files in the System32\Tasks folder.

Task Scheduler now opens without errors but is empty (no tasks) as expected. I went to my backed up Tasks folder and noticed all 123 files didn't have an .xml extension although opening a couple in Notepad confirmed they are xml files. I realized attempting to import one that they needed to ne named with the .xml extension (not mentioned in the answer for this thread).

Anyway, I was able to finally install the connector software which created several WHS-related tasks. I am in the process of doing a backup.

I feel like, at a minimum, certain system related tasks should be restored. Is there a way to get all the required Windows system related tasks back without importing one by one? It seems like a huge task to do this manually, ie renaming each xml file with the appropriate extension then importing it into Task Scheduler. 

I read about a system refresh in Win 8. Does this, or something similar to it, exist for Win 7?

Thanks for your patience with my long post.

I only have HKEY files. I don't have HKLM. I assume something is wrong. How do I correct it.

Windows7. IE: Version 11

The ANSWER doesn't work.  When I found the above path, it would not allow me to delete. HELP, PLEASE!  THANKS.
