Do you want something grown-up for your desktop this Christmas season? Then download the free Windows 7 Christmas Theme and enjoy.

This festive Windows 7 Christmas Theme contains five stylish and tasteful wallpapers: white reindeer flying against a red background, a tiny Santa hat emerging from a white background, a close-up of ornaments on a tree, holiday wishes on a red background, and a blue-themed montage with snowflakes and ornaments. Nifty touch: The window color changes to suit each theme. Your system sounds change to Microsoft's cheery Festival sound theme.

Note: To install this theme, just uncompress the zip archive and double-click the themepack file within. Windows does the rest.
