Hello
Is your computer displaying any symptoms at all?
If not, chances are, you don’t need to buy Norton Utilities to “fix” registry issues in Windows 11. Often times you don’t need to touch the registry at all. Norton 360 (and other security tools) tend to flag “broken” or “invalid” registry entries, but most of them are just leftover entries from uninstalled programs. They rarely cause actual problems. In fact, I recommend staying away from any third party tools that claim to clean your registry and repair it. They often times cause more issues than fixing.
