After updating to Windows 7 SP1 I updated with every new update that came out, but there were problems with the last two:

UPDATE: In the updates history I have found a lot of updates failed:

What can be done? Can I manually update?

P.S. I was offered a fix for this: Windows6.1-KB947821-v12-x64. Should I install?

Have you been try to download updates after restarting PC or not. Try and then give a reply hopefully it will work for you. –  avirk Aug 7 '11 at 14:08
    
Restarted PC and updates are still failing. –  Boris_yo Aug 8 '11 at 14:39
    
The answers doesn't help you?......Strange....What settings you have for updates? "Let me choose which download and when to install them" setting I think you have set it to Install Updates automatically. –  avirk Aug 8 '11 at 14:55
    
And of course you should take a try with that HOTFIX provided by Microsoft for windows update issue. As in my case when I used XP there were a problem with hibernation and then I found a HOTFIX for that and after installed it I never face that problem again. –  avirk Aug 8 '11 at 14:58

Like the dialog says: reboot Windows. Then check WindowsUpdate and try to install any remaining updates. If that keeps giving an error then you can try to manually install the updates.

I think you should have to change settings for windows updates to this way got to Control Panel\All Control Panel Items\Windows Update\Change settings and set the 2nd option from drop down menu "Download Updates but let me choose whether to install them." –  avirk Aug 8 '11 at 15:01
    
Look up the kb number on Microsoft's website and download the msu file. –  ZippyV Aug 8 '11 at 21:28
    
Thanks that helped. –  Boris_yo Aug 8 '11 at 23:17
    
@Boris_yo Can you elaborate on which of ZippyV's suggestions solved your problem? –  Mark Johnson Dec 31 '13 at 21:15

Yes run the SUR tool as instructed Here

If you receive the Windows Update error 800b0100, it means that a file needed by Windows Update is not registered with Windows correctly. The System Update Readiness Tool can correct some conditions that cause this error. To use the tool, follow these steps:

  1. Go to the System Update Readiness Tool webpage. In the Information for advanced users section, find the version of Windows and system type of your computer, and then click the link to download the System Update Readiness Tool. If you don't know which version of Windows you have, see View your computer information.

  2. Run the tool

  3. Run Windows Update again.

Note:

Typically, the scan takes 15 minutes or less, but it can take longer on some computers. The Windows Update progress bar is not updated during the scan, and progress seems to stop at 60% complete for some time. This behavior is expected. The scan is still running and you should not cancel the update.

If the problem persists after you take these steps, go to the Microsoft Update Solution Center website to find more information about the error code or to request support by e‑mail.

Error codes this applies to:

WindowsUpdate_800B0100

0x800B0100

System Update Readiness Tool did not fix the problem. –  Boris_yo Aug 8 '11 at 22:46

When faced with a 800B0100 error from Windows Update, if the System Update Readiness Tool won't install or doesn't fix the problem, try the Windows Update Troubleshooter. That worked for me.
