CCleaner damages Win 10 update !

Hello.

Thought I'd let you know about a serious problem I've Just had.

I updated to Windows 10 from Windows 7 Family version. No trouble for the update...just several hours long ! Anyway, once everything was working I ran CCleaner. That was the first and only action I carried out. Big Big mistake when I ran the registry tool !

Effectively I lost all Audio and the Film & TV App in Win 10. I probably lost other functions but I couldn't see them. Yes I did save the registry changes. But when I reinstalled them it fixed absolutely nothing. I had to roll back to Win 7 and then do a new re-install of Win 10. And now everything is back.

No idea what went wrong as I did check the list to be deleted and I didn't see any reference to my sound card or software nor to the film & TV app in Win 10.

So please be advised - and please make CCleaner safe for Win 10 !

All the best,

Philip
