Latest Vista Update stuck in Stage 3/restart loop
I have Vista Business system on a Toshiba notebook, latest Service Pack and with all updates. It was fully functional when i last shut it down. I just booted it up to find the Stage 3 page of a Windows update. 0% progress shown, then it restarts, and
opens at the same page again. Stuck in this loop. Have tried using F8 to get last good installation, and to stop auto restart, without success, it just keeps returning to the Stage 3 page and reboots. Tried Systems Repair which offered a System Restore,
but that wouldn't start. System Repair now just keeps showing progress (for 3/4 hour) without any HD activity. I shut it down and it still restarts at same Stage 3 page.
