  4. I did this (thank you!). I am having the problem now that I cannot see my programs in the Start All Programs tab; I only see an empty open office folder. I can open excel and can find it using the search, but it doesn’t come up in my All Programs list. Any ideas?

  5. I cannot view my desktop also, anyone know how to get icons and program files back in the start menu back? Thanks!

  6. For anyone else that runs across this one, your start menu items and desktop items were set to hidden mode. You can get this back in place by removing the hidden checkbox on the directory for start menu and desktop. Be sure to apply the changes to the subdirectories too.
