I got in to work this week to find four windows xp computers all having the same problem - they are all hanging on the windows loading screen (the one with the logo and the green progress bar).
The only thing I could think that would cause this to happen on all of them at the same time are bad windows updates.
Can anyone shed some light?
Edit: some further details: CAN get to safe mode. System restore DOESN'T help. HDDs are ok. All were working fine last week.
