It's easy: Use RegShot. Download: http://www.majorgeeks.com/download.php?det=965 or http://www.webattack.com/get/regshot.html It can make a "before" and "after" shot of your registry. So you make the first shot, then make a change in TweakUI, then make the second shot, and RegShot will compare them and show you what was changed. You can find out everything with this! Much thanks!!!!
