Windows 10: broken registry keys

I've just managed to reinstall Windows 7 and upgrade back to Windows 10 after blue screen failure. re-installed Norton 360 and smart scan saying I have 124 broken registries and a 'slow programme'. how can I have 124 registry issue already? I've already run both SFC and DISM commands - anyone help or is this just a Norton marketing ploy?

Can NOT remove ATITool registry key!

It's low priority to stop ATITool from making undeletable class keys in the reigstry?

That's about one rung above spyware.

What bothers me most is that I'm pretty sure you can't protect a registry key by any simple means, something must still be running somewhat that is protecting that key. Even after I manually removed the service. That's what bothers me.

 

ATITool registry key

Hello,

During ATITool installation, the following registry key was added to my registry:

"HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{85b5ddd0-e090-4b15-bdf2-a443a3ca0b66}"

After uninstalling the program, this key remained. I tried to delete it through the registry editor but it returned the following error:

"Cannot delete {85b5ddd0-e090-4b15-bdf2-a443a3ca0b66}: Error while deleting key."

I'm running Vista Home Premium 32-bit by the way. I also tried to change permissions for the key and deleting in safe mode, but neither of those worked either.

Any ideas on how i can remove this key? Any help is appreciated, thanks.

Choosing Last Known Good Configuration provides a way to recover from problems such as a newly added driver that may be incorrect for your hardware. It does not solve problems caused by corrupted or missing drivers or files.
