I installed a new computer. After I installed I updated everything and let the computer run for days. Then I don't know what my daughter did. The computer stopped responding, and Windows update no longer work.

People said to run Microsoft's Fix It tool. Fix It ran and after that the problem still persist and it still doesn't work. The problem changes though. Before there is some error code. Now windows Update simply says "Updating", and never ends.

So I downloaded KB947821. It's been 3 hour and it's still installing.

Looks like it hit firewall or something. i don't see windows update on firewall exception list. However, I've never heard that this is an issue. Firewall only protect against incoming transaction, not outgoing right? Or what am I missing.

What should I do?

In the first releases of KB947821, Microsoft warned customer on the information page about it that it would appear to be stuck: it still does that, but their warning seems to have disappeared.

I'm running it on my system at this very instant and it looks like it's stuck, but it isn't. Do not worry: just start it before you go to bed and forget it. If it still seems to be stuck when you wake up, then it really is stuck. You probably are going to want to run System Restore, to any time prior to when your daughter had the computer, since you don't know what happened when she was using it.

But before doing anything, even the KB947821, run a quick scan with whatever security program you are using. Then run checkdisk, but run the complete scan (it will be a 5 step process):

  • Go to computer, right-click on your HDD and select Properties.
  • Go to Tools, under "Error-checking" click "Check now", and in the little box that comes up, put a checkmark in both boxes, then reboot.
  • It will run when it reboots, and will take hours to run, depending on how big your drive is.
  • When it gets through, open an elevated command prompt (type command into the Start menu search box, then right click on "Command prompt" when it comes up and select "Run as administrator").
  • Type in sfc /scannow, then hit Enter, and let that run. It may take a couple of hours.

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. That's your "second opinion" on security. I get a "third opinion" also on occasion, one of the online free scans, Trend Micro's House Call.

All of this will take a day. If your system isn't working at that point, you need to try System Restore. 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 sfc to work.

This article has some information on how to proceed when updates freeze. Looks like a good place to start with before we look at the last option of a re-install.

It is better to set update settings to Manual and let you suggest installing updates instead of automatic. This gives you the option to install updates only if it is necessary for the system.

Secondly, I've had to face this once on a fresh install, and only reason i could find was some windows update conflicting. Only fix that worked for me is a reinstall and configuring update settings to check for updates but ask me before install from automatic. There are updates not required at all which doesn't need to be installed. Make use of the description. A little effort on googling will make it easy to decide if this update is really needed or not. –  Kappilman Sep 9 '12 at 5:51
    
I reinstall. Install the lan. And then do update a little at a time. Yea, check updates, but let us choose whether we wantto download or not. –  Jim Thio Sep 9 '12 at 8:39
    
Your answer will be useful once I have an old installation. For this one, I'll just reinstall. Thanks anyway +1 selected. –  Jim Thio Sep 9 '12 at 8:41
