Would that effect the stability of your Addon Manager and protection System in any bad way?
Your serial number is stored under HKEY_CURRENT_USER\Software\Fsdreamteam. As long you or your tool doesn't touch those keys, nothing else in the registry *RELATED TO YOUR ACTIVATION* is there.
Of course, there are tons of *other* things in the registry that can affect our software, that do not have anything to do with the "protection", like registration of Windows system libraries, user permissions, file system settings, user policies, compatibility settings, shared libraries.
So yes, lots of things can go wrong when using a registry tool, that can affect the Addon Manager, but don't have anything to do with the protection.
