[How do I restore a registry, Where can I find the files I've backed up using CCleaner?]

I was able to search using the file explorer by dropping down the search tab and hitting "This pc" on the left

though It didn't find or actually search instead it displayed everything

 

And you where right It was in my OneDrive folder! <- I was confused here because It is not in my default Onedrive that displays on my computer but in a specific user onedrive

 

I wanted to ask if the bad registries will affect a complete re install of windows 8.

I figured out the registries should be in my documents folder but they are not there. So I think my only option is to move everything onto an external hard drive and restore my computer

Thankyou for your help and advice!

Most if not all of my applications have reset. Its as if the computer has been reset for example I have to rechoose default programs to open file types.

So my windows 8.1 just broke.

I still have all my data but my taskbar was swiped clean. Pooki is gone so I ended up having to use the actual windows 8 start menu thing and when clicked on it is a blank blue screen. 

 

So I think this may have been caused by cleaning registries and I know for a fact that I chose to backup when asked by ccleaner. I'm not sure where to find it and I cannot search anything on windows for some reason, also the text is all the same even on browsers and many applications are blurry

 

It says

By default these files will be saved into your 'My Documents' folder.

 

I cant find it in my "Documents" folder and don't have a "My Documents" Folder

 

Please help!
