Hello,
I recently run into a problem with CCleaner. I used it to clean my registry, and after that Windows 10 could not boot again. I could not even repair it with the usual safe-mode, reset, or restore routines. So I had to reinstall my Windows 10.
Now, I have used CCleaner to clean my registry for years, and this is the first time this happened. It might be CCleaner's fault or perhaps something else happened that day e.g. installing a video driver.
This was an eye opener for me, so I want to inquire. What is registry backup really for? Is there anyway to use it when the OS refuses to boot up? Or is it for less serious errors e.g. a messed up start menu or something of this genre; that I can fix by restoring the registry from the backup?
Cheers.
