I have set the users desktop through group policy, but this only works when logged in. When I log off, the desktop still shows my preferred desktop, though if the logon dialogue box is moved it's like a paint brush which rubs out my desktop, and leaves a plain blue desktop.
After reboot, the plain blue desktop is shown again until someone logs in when my desktop is shown again.
I'm looking for a desktop (my one!) that is shown on boot, and not 'removeable' when logged off..
