So this is only for Windows XP users.Its XP tweaking pack which contains 53 registry tweaks.You just need to click on those registry files and then it will automatically register the key.It includes tweaks like enable/disable hidden files and folders,Clear cache on Reboot,Change Size of Desktop Wallpaper to Suit + Undo.etc.It also contains enable keys as well as disable keys.
These keys are not made by me.I just found them yesterday while finding some tweaks for xp.

I would do this but i just don't want to risk messing anything up. Plus, i'm not too happy being an xp user at the moment, since they upgraded IE9 for every other system, BUT Xp.
