For some of our Windows 7 Installation, on installing, downloading etc(Anything using the progress bar or ring(such as logging on, shutting down and configured Windows updates)) a majority of the time unless you actively move the mouse pointer the progress bar either lags so bad it appears not to move, or in some cases, wont move at all even with the basic(non-areo) themes on what seems to always happen on the administrator account only sometimes.
The pc I’m having the problem with right now is an Optiplex 760 with 5GB (4.84GB usable) of Ram, Windows 7 Professional 64Bit
