I did the windows 10 upgrade from 7. Some of my family members didn't like it so I did the downgrade back to 7. Turns out there is an issue when doing this that corrupts the files in the task scheduler. It doesn't allow me to run any backups. Many people having this issue. Microsoft has been dragging their feet on a fix. An open source software company called Codeplex came up with a fix for this issue. Very small download that corrects the corrupt files. Only problem is that norton blocks it. Has anybody out there turned off the norton and used this software? It has many great reviews but why does norton not like it?
