So, I am revamping windows XP with windows 10 icons and windows 8 sounds. but, when I was trying to replace explorer, obviously there was that error you get when renaming something to a file that's already there. then I delete the file. then rename it again. Error!! File exists with that name! what?! so I delete it again and rename it. Error! so XP has a builtin system that replaces any foreign or nonexistent explorer.exe with the default. Also, aero cursors look like shit on XP.
