Win10 RollBack Problems... Can I restore the registry like this?

After having a slew of problems with the Windows 10 upgrade I rolled back to Windows 7 today. Sadly I discovered that this left 30ish Tasks in the Scheduler either corrupted or tampered with and broken. This article/thread explains the problem.

The thing is that 3-4 days before I did the upgrade I cleaned up the registry with Ccleaner and at the same time made a full backup of the registry using regedit.

Would it be safe (and would it fix my Tasks) if I were to simply replace the entire registry with the version I backed up last week before upgrading? I have never actually had to restore the registry before and I am not sure whether replacing the entire thing is possible, practical and whether it could cause more problems than it may solve. As I understand it registry changes are made constantly in windows and I don't know if replacing my entire registry with a 5 day old version is a dangerous thing to do or not.

Any thoughts on this would be much appreciated. Thanks!

Btw I cannot do a system restore because there are no pre-update restore points left.

I installed Windows 10 on Friday (22/04) morning and used it Friday, yesterday and half of today. When I rolled back it had been on my system for a little over 48 hours. The last registry backup I have is dated the 18/04, so from last Monday.
