• Code 80072EFE. Windows has encountered an unknown error when you try to install the updates.

  First of all.  I have Windows 7 ultimate.

  Recently, I had problems with malware.  I have to click on a link to google search and get sent to some site asking me to buy stuff (I have not).  I tried several different anti-virus and malware, including:

  1 McAffee (which is a joke)

  2 avast

  3. stop Zilla

  4 Malware bytes.

  1-3 have not picking up anything either.  And 4 stopped working after 10 minutes through a thorough analysis.  With a quick scan, we didn't find any malware.

  I tried safe mode and nothing.  So I restored to an earlier point when it was working fine.

  I tried to download the updates, but I get an error 80072EFE and am unable to download the updates.  I checked McAffee and all windows programs have full access, so there should be no firewall problem.  STOPzilla and Avast are no problem, due to the restoration.  I need help! Help, please!  If the cat is available, would be great.

  Thank you

  See if this triple McAfee fix solves the problem: http://service.mcafee.com/FAQDocument.aspx?id=TS100507

  For good measure, also make a Reset (see http://support.microsoft.com/kb/971058).

• Error 6 B 7 Windows has encountered an unknown error when you try to install the Office Live update 1.5 on the House system top of range of Vista SP2 64 bit with Office 2007 is installed.

  On a m950y of HP with AMD Phenom Quad Core processor 2.4 GHz, 8 GB of RAM, lots of available hard disk space, accepted the software license agreement. Can you tell me what's happening, if this should be fixed, and how it can be fixed?

  Mike-

  UH! After posting the added information in my last post, I have acted on an intuition, uninstalled, Office Live 1.5 from the Control Panel, rebooted, reinstalled and everything went well.

  So I guess there's a glitch somewhere where Windows Live Update thought I needed the upgrade while in fact I have not, and he is involved in a problem that cannot be resolved.

  Thank you for your help.

• Code 8E5E0147 Windows Update encountered an unknown error

  Hello

  
  

  Vista has got an automatic update every day for a few days ago but every time the update starts finally fails with this error: "'Code 8E5E0147 Windows Update encountered an unknown error" "

  
  

  What should I do? Vista Help did not help at all. I got the same error.

  
  

  Thank you.

  suiobo,
  Go to Microsoft's download page and select the download appropriate for your operating system, then save it on your PC.  Then, run the update from your PC and see if it will install manually.  If you still have the error and then perform a clean boot and test again.  Let us know the results.

  I continue to encounter this error when you try to update windows.  The steps I have is use selective startup in msconfig to disable all process/services non-windows before running Windows Update and I still received the error.  I checked my update history and don't have any error codes listed.

  There are many updates to install? If so, can you try to install some both (miss those who are updates .NET)

  Indeed, none of them are updates to .NET?
