Prevent saving onto the Desktop

Hello all,

I have a real simple question. How can I prevent users with a ‘Limited Account’ to not save files onto the desktop?

Iam looking to not buy any external software to accomplish this task. I some someone can help.

Also, keep in mind that this is for a Windows XP Home edition, there is no Group Policies available.

Thanks for your support in advance.
