I have received SP1 this morning via Windows Update. It started to install and asked to reboot to finish install. I went to lunch and after several hours is still doing this: Show a message in the screen Installing Service Pack: fase1 of 3 0% completed After more less a minute it says Shutting Down and reboots When it restarts it shows the above message again... Time after time, it's been doing this for the last 5 hours! Can anyone help?? (Please apologize if the English is to perfect. English is not my first language)
