Does it happen while you're on the computer, or after it has been shut down?
Hi a10,this changing of appearance happens while i am busy working w/apps on my desktop.the windows logo pops up in the middle of the screen w/a message of PLEASE WAIT,then the whole desktop goes grey dim for a few seconds and then all windows revert to old windows classic or xp appearance.the only things that do not change are the desktop pictures and the screensaver apps. active/inactive titlbars,scrollbars,background,caption buttons,window borders, font colors all revert!these parimeters have been set under display properties/appearance tab/advanced but something in windows OS takes charge. HELP! Thanks for your diligance! Chuck.
