You can start by using Windows search, to find Local.reg. Make sure to include system folders, hidden files and folders, and subfolders in your search. When you find it, you may want to open it in Notepad, just to see what’s in it, although this is not necessary. You DO need to rename the file, to something like –Local.reg
Shut down and restart your computer. Hopefully, your problem will be gone.
I hope this helps.
