One of the screw up things in windows is the registry key because it always keeps hanging around especially when you uninstall the software. So, I recently find out this CCleaner tool (free) to clean up the registry and it turns out to be pretty good and reliable.
Another thing that I use for this CCleaner tool is to remove all those useless applications that come by default with Windows 10. It improves my laptop performance significantly after that.
Unfortunately, you can NOT uninstall these applications with the "Add & Remove Programs" that you can find in the normal control panel. So the best method is to use the CCleaner tool to remove them.
