Windows's activation price is astronomically stupid (in my opinion), so I copied this batch file command from this this article.
All it does is get rid of the stupid watermark that Windows forces over everything.
It occasionally bugs out when some games are running, so this is just to stop it from doing that, by completely hiding it.
This does not stop the fact that you can't use certain settings (like default audio device?) but it at least gets rid of the watermark.
@echo off                   
taskkill /F /IM explorer.exe
explorer.exe                
exit                        
Random optimization stuff that I always forget (lol).
