The first three relate to norton security do you still run norton? If so don't remove them

We recommend that you don't regularly use the Registry Cleaner with Windows 10 or 11, only use it if you have a specific problem.
The Registry Cleaner is meant as a tool for fixing things if there is a problem, it is not meant for regular use.

Using any registry cleaner will not speed up your machine in any way, and only saves a few KB of disc space.
Using a registry cleaner on a healthy machine can even 'break' it.

Windows 10/11 changes the registry too often to make using any registry cleaner totally safe.
You might get away with using one - but doing it regularly can, and does, lead to problems.
