How to Reset the Windows Registry to Default
The Windows Registry contains a ton of values that make your operating system (OS) run in a certain way. Many times, for cool customizations or fixes to issues, editing the Registry is the only way to make the change.
This is why it’s a good idea to make a restore point before you make any Registry edits. You can also back up Registry entries so you have a copy to restore if the operation goes south. However, if you’ve done neither of these things and damage your system, you’re probably looking for a way to reset the Registry.
While there’s no official way to “reset” only the Registry, you can use Windows’ built-in refresh tools to get everything back to normal. Type Reset into the Start Menu and click Reset This PC to enter the appropriate menu.
