Problems after installing win 10 and then rolling back to win 7

Hi guys

Tool the plunge and rolled back to windows 7 after having huge problems with win 10.

Problems now are as follows - that i've found so far:

Various updates won't install and just keep failing.
Task scheduler keeps saying it's corrupted with the following files, task uploader, task background config, task ractask, task windows parent controls, task ip address conflict 2, task ip address conflcit 1, backup.

also I've just found out the reliability monitor is blank.

Can you please just put me on the right lines of where to start please?
Thanks

Thanks for this link.

I downloaded the tool and managed to almost fix my problems - only two left now which is brilliant compared to how it was.

The last two which are still showing are these and I have posted on the other discussion board as well.

Task image corrupt: Microsoft\Windows\Customer Experience Improvement Program\Uploader
Task image corrupt: Microsoft\Windows\WindowsBackup\Windows Backup Monitor

The manual steps in this post might work for those two:
