Windows again. I think I've commented before on apps dumping their icons on my desktop. Usually they do this by adding them to the Public Desktop folder. Windows doesn't have an official way to stop the public items from showing up on your personal desktop, but a common workaround is to go into the security settings and deny read access by your normal user account. This has the effect of making all the public icons disappear.
Alas, an update in the past couple of weeks has broken this workaround. Windows will now periodically revert the permissions on the Public folder and make all the rubbish reappear.
