Now that the download period for Windows 7 Beta is over, many people may have lost their chance to try Microsoft's new operating system. If you're among them, worry not: you still have the opportunity to take a sneaky peek at Windows 7, even if it's only by disguising your dear old Windows XP as the new Microsoft OS.

SevenVG RC Theme is a nicely tailored Windows 7 skin that gives Windows XP the new look. The theme is dead easy to install – something you don't usually find in this kind of software - and includes a wide array of changes: new fonts, new common tasks bar, new window style and much more.

Like I said, SevenVG RC is very easy to use. Simply follow the instructions provided by the developer on his website and you shouldn't have any problem. Bear in mind though that you need the uxtheme.dll file patched to be able to use this and other third-party themes.

The only thing I missed in SevenVG RC was a bit more extra material. It would have been great to also have Windows 7 icons and cursors, more wallpapers and some of the extra features you get in the new operating system, such as Aero Shake (which lets you minimize all windows by shaking one of them with the mouse) or Aero Peek, with which you can make all windows transparent.

SevenVG RC is probably the easiest and fastest way to give your old Windows XP a fresh, brand-new Windows 7 appearance.
