Turned on my laptop earlier, and tried checking for updates. Saw around 250MB worth of updates, clicked install, and Windows Update locked up shortly afterwards. Restarted Explorer, and Windows Update still wasn't working, so I rebooted. Tried checking for updates again, and now I'm stuck on that screen (the progress bar moves, but it's seemingly not finding updates). No idea what caused WU to freeze. My desktop (set up in basically the same exact way) handled it fine. Any ideas how to fix it? I tried a Disk Cleanup (to cleanup WU files) and a reboot to no avail.
