I wanted to back up my computer for the first time (shame on me), but this was my first error message.
I was able to determine on my own that there are 43 tasks involved. I went to Microsoft's community for help and was told first to do the Workaround #2 from that security update KB2305420. I did that and when I got to the task scheduler library, the message window there covered any action that I might be able to take regarding deleting the affected tasks.
So, I went to the Microsoft community forum and I was told to do a clean boot and that was supposed to fix it. It didn't do it.
I ran a system file check and no system issues (or whatever it said) were found.
I discovered a website called "repairtasks.codeplex.com" whose theory is that when you up-grade to Windows 10 and then go back to Windows 7, you get a multitude of errors. I had done just that. They offer a free download to fix that.
so, I asked the well-respected men at TechSupportForum what their opinion of them was and got the all clear. I tried to download this program, knowing that in just a few minutes my computer would be cleaned up and I could start backing it up. Not so.
The error I got this time was "You don't have the appropriate permission to access the program". Now what?
Who do I go to to get that? I tried to contact repairtasks.codeplex.com but they don't hace a contact link. I don't want to buy an online service to keep my computer backed up.
Or, do you know of a better way to fix this?
