Edit: I read that simswki page better and it seems like that if I use CCleaner first it will already automatically clean all of the registry keys... it is correct?

Please tell me a way that doesn't hurt my laptop health... Believe me, this is so stressful. if you can summarize everything I would really appreciate it

Right, there shouldn't be any need to go through those manual registry cleanups if using CCleaner instead. The manual way is actually more prone to user error or accidentally skipping a step. You aren't going to ruin your laptop by cleaning the Registry with CCleaner. But let's say something really unlikely and unexpected did happen and as a last resort Windows needed to be reinstalled -- that's annoying and time consuming, but not anything like permanent hardware damage.

I'm not an expert on these utilities as I don't spend time on a typical day uninstalling and reinstalling the same software even professionally, I am just a casual user. If a user's office workstation in my care did start malfunctioning to the point where certain critical pieces of software no longer worked, I would be more likely to format the drive and start over with Windows entirely (after giving them a replacement to use, a luxury we don't typically have at home). But I did use this method on my own computer while transitioning TS3 from Origin to Steam a while back and it all went fine.
