I don't see Windows Update on the firewall exception list. The firewall only protect against incoming connections, not outgoing right? I'm running it on my system at this very instant and it looks like it's stuck, but it isn't.
3) Click the Update button next to any flagged device to automatically download and install the correct version of its driver (you can do this with the FREE version). 10) Go to C:\Windows, right-click Software Distribution and click Delete. 15) Wait for while for Windows to search for the updates for you. If you can see any DNS server IP addresses listed, write them down for future reference.
If that doesn't work, you will have to repair Windows one way or another, by doing a repair install or something of the sort.
You may have to use the recovery console to get System Restore or even Welcome to Super User!
Then run checkdisk, but run the complete scan (it will be a 5 step process): Then and only then get the latest KB947821 (keep a copy on your desktop or on a removable hard drive; they just released a new version) and run it, as you have done.
And run a complete system scan with your security program, then get Malwarebytes free version, download it, update it, and scan your system with it. I get a "third opinion" also on occasion, one of the online free scans, Trend Micro's House Call. If your system isn't working at that point, you need to try System Restore.
