Windows 7 themes for Windows XP and Vista
As is often the case, themers have been more than happy to create transformation packs that allow Windows XP users to skin their desktop to look like Windows 7. Brad wrote about one from DeviantArt users last year - when it was assumed that Windows 7 would look pretty much the same as Vista.
Now, however, we've got some options that more accurately reproduce the superbar and other features that distinguish Windows 7 from its big brother.
Vishal Gupta has done an excellent job with this theme. It's simple to install, looks great, and features both normal taskbar buttons and iconized mode.
Windows 7 Complete
What would a theme post be without at least one reference to DeivantArt? User DopeySneezy calls this one Complete, and he's not kidding. Includes Windows 7 style system properties, display settings screens, and more.
Seven Remix 2.0
Niwrad Soft recently updated his theme, and it's even more convincing than V1.0. Some users have reported .dll error messages, though I didn't receive any during my tests.
For a less complete tweak, you can convert your taskbar to the superbar using the tool created by another DevArt user, flawless02.
Windows 7 Essentials Pack
Another winner from DevArt, this one by Ka-Booka includes just about every UI tweak you could possibly want to make Vista look like Windows 7 - even a Windows Media Player 11 mod, though some of you may choose to skip that one based on previous feedback about the new look.
