Well, for those using microsoft windows xp, any version may do. All you have to do is right click my computer, then go to properties, then on the lower right side corner you can see there a tab that says advanced. Select it once, then under performance you have settings, as you select it, you can see those options which do have checks. This is the trick, you uncheck everything except for two: Use drop shadows for icon labels on the desktop and the other one is use visual styles on windows and buttons.
Another option you have is directly selecting the tab, adjust for best performance, in this case, your recent theme will be replaced by the basic theme that windows has.
You may reboot your pc and experience the difference. Enjoy! and I hope you enjoyed this tweak!
