Word to the wise, We are getting nationwide reports from customers of one of the latest patch releases being deployed to W7 clients causing PCs to sit on 'Configuring Updates' at the 9-12% mark for anywhere between 2hrs and 2 days.

Experienced this on Friday on 2 clients myself, and the latest one I'm working on started to grind to a halt with pending updates, and although I hard-powered it has continued with the pending update tasks.

Either takes aaaages to complete. Or fails after a few attempts before re-queuing it.

Can't find any statement on the interwebs for the past week relating to it, but with the number of complaints and others I've spoken to seeing the same there's a fair chance it's common.
