LinkNow that Windows 8 images have begun leaking out, it's only a matter of time until developers start releasing mods for Windows 7 which mimic upcoming features. Over at Into Windows, they've spotted one such mod already.
In the earliest Windows 8 images, we saw Windows Live integration on the taskbar. In the far right corner, there's a user tile displayed. If you'd like to do the same on Windows 7, download Taskbar User Tile from DeviantArt user AngelWZR.
