No scheduled tasks will perform on CIS.

I did make a post a while ago about this problem, but I on;t stated that it was scheduled virus database update that was having the problem. However, I have now discovered it is all scheduled CIS tasks. No other applications are effected. I have uninstalled and reinstalled CIS, but no fix. The way I have verified this is by going to the task scheduler and force running all the CIS tasks, and none will run. There isn’t an error, it just doesn’t do anything.

I am running Windows 10 64bit upgraded from Win 7 64 using MS upgrade.
I have a screenshot.
