Skinning

Wanting too skin XP a little nothing too flash just too make it a little bit different. Used style xp but found the themes didn't install well and also it wouldn't let me access remove progammes. Also kept downloading other programs and installing them without me allowing it so that has now gone. then i tried litestep but can't seem too find any skins and looks a bit complicated too use. any help with that program would be good.
Can anyone recommend a skinning program thats easy too use not full of ads bugs or trojans?
