I get this error when I click onto Task Scheduler. See below in the upload. A solution/s would be appreciated.
@wolfrun, see Error message 'The selected task "{0}" no longer exists. To see the current tasks, click Refresh’ and scroll down to the last posts. I had the same error on Win7 64-bit, and changing the Disk Defragmenter to Weekly fixed my issue. Worth a try.
Defrag was the culprit. I deleted that task in the registry found in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft" which was in your above info .. Thanks JR....And yes that is what I'm in also Win.7 64 bit also.
