How to set up rotating wallpapers through GPO

So, my guestion is "easy" in nature, not so easy in solution...

my boss came up with a brilliant idea of having wallpapers changed every 30 minutes or 1 hour or something. In short, he wants active desktop from windows 7 but this pushed through a GPO.

For windows XP machines we would like this to work as well, but if we can get it working on windows 7 machines for now that'd be great.

anyone able to point me to a guide, how to, or tell me how to get started on this and where to find the right option to do this in the GPO's ?

Cheers

• You should be able to do this fairly easy. Although, as many have commented, it could be particularly irritating to users.

  1. Create your customized theme.
  2. Deploy the custom theme to clients, including wallpaper images.
  3. Configure Group Policy to select your custom theme.

  The .theme file format is fully documented in this MSDN article. You will be particularly interested in the Slide Show section. The Group Policy option titled "Load a specific theme" can be used to select your theme. There is also a policy option to disable users from changing the theme.
