It's obviously not convenient, but if you want to reset your entire registry to its default settings, this is the only method. However, there are other ways to go back in time with the registry, or give yourself a backup in case of future problems. Let's consider those. System Restore is a recovery feature built into Windows. Whenever you make changes like installing an app or a major update, Windows creates a restore point.
You can later use these restore points to undo the changes if they cause issues. Using a restore point will undo any changes to app, drivers, and system updates since that point in time. This includes the tweaks that such actions make to the registry, allowing you to reset some parts of the registry that you've recently modified. This method isn't perfect for resetting the registry, though. It won't let you entirely reset the registry, unless you created a restore point as soon as you started using your brand-new computer.
Even for less drastic resets, you might not have a restore point from right before you made changes. Windows lets you make a restore point manually, but that doesn't help if you're already having a problem. The Registry Editor makes it easy to export registry entries to keep them as a backup, share them with others, or similar.
This is another case where you're out of luck if you didn't export anything from the registry before you wanted to reset it. For the future, though, it's good to know how to export registry entries and import them later to restore the backup.
