Fix Regedit.exe Crashes when searching through Registry

If you have recently updated or upgraded to Windows 10 then while searching through Registry Editor, it will take forever to perform the search, and when you click cancel, the regedit.exe crashes. And when the Registry Editor crashes it gives an error message saying “The Registry editor has stopped working“.
