Try a system restore, if that doesn`t work then you could try a repair install, or use the PC`s own recovery process, but that will take it back to a brand new out of box condition. That would be your last choice.
Backup all your data first.
The only software to use to clean the registry is ccleaner, don`t use anything else.
Thank you !!
