This theme provides a number of jack-o-lantern wallpapers with a creepy outlook that is likely to make your desktop glow with the Halloween splendor. Time to dress up and carve that jack-o-lantern with the Trick or Treat theme from Microsoft.

Since it’s time for everyone to be wicked and creepy, we decided to join the Halloween ‘spirit’ by delivering to you some spooky Windows 7 theme packs. The Halloween magic is in the air, and with it have come the Goblins, Witches, Demons and Ghostly entities to go trick or treating (or maybe they’re just annoying kids knocking at your door!).
