You're facing a common issue when files get mixed up in regedit. To reset your registry, you'll need to use the built-in tools in Windows. Try opening the Registry Editor and navigating to the root folder, then safely delete or reorganize the files you don't need. If you're unsure, consider using a backup method first. Let me know if you need step-by-step guidance!
You might want to use CCleaner. I'm not sure if it effectively cleans your manual changes, but I hope it works.
Only removes empty files, apparently. Regarding cleaning the registry, it's generally not recommended. There are no advantages and significant dangers involved.
Use Regedit and the registry viewer to manage files, but remember it doesn’t offer an undo feature. You’ll need to revert manually by restoring from a previous backup or using System Restore, which will revert your system to a point before the changes were made (without impacting your personal data).
If it isn't an available choice, restoring Windows is the most effective solution. (Save any crucial files to another storage before reinstalling)
