XdN Tweaker is a free tweaking program for Windows XP, Windows Server 2003, and Windows Vista. It sets itself apart from the other tweak programs though by not being filled with options, settings, and "tweaks" that are actually normal options and menu settings of other programs. It tries to fill the gaps that other tweak programs overlook. Instead of just being another way of doing something you could do yourself just by clicking on "options" or "settings" in Windows, it offers features that Windows normally wouldn't allow you to do without digging into the system registry. Depending on if you run the program under Windows XP, Windows Server 2003, or Windows Vista, different options will be available to you (works with 32-bit and 64-bit Windows).
