I ran Windows update on my Vista Business edition yesterday. It shut down and restarted, but eversince has been in an endless loop between "Configuring updates: Stage 3 of 3 - 0%" and shutting down.
I've tried deleting pending.xml from C:\windows\winsxs directory using the ThinkVantage repair options.
I've seen this and see that 2/3 solutions involve a restore point, which i don't think i have, unless it's automated somehow and is there i just don't know it.
Rebooting into safe mode just returns to the 'configuring updates screen'.
Rebooting from an iso image of Vista SP1 doesn't work, as various files aren't found.
I'm getting really tired of this. It's been in this loop for nearly 18 hours now. Any ideas what's going on and how to get my system back?
