Is it safe to clean out my system registry to speed up my PC?

No, it is not safe to clean out your system registry to speed up your PC. It is best to leave the system registry alone, as there are important files stored in it that are necessary for your computer’s proper functioning. If any of these files are deleted or corrupted, it can cause major issues with your computer. In some cases, deleting or modifying entries in the registry can even cause your computer to become unbootable.
