Windows – Why does Windows 7 update fail with error 800706BE

windows 7windows update

I have 18 updates appearing for Windows 7 x64 but when I try to install any of them I get the error 800706BE.

The Microsoft help that appears gives several solutions:

  1. Fix It button. This downloads MicrosoftFixit50123.msi (963KB). After running it displays the message "This Microsoft Fix It has been processed".

  2. System Update Readiness Tool. This is actually in response to error 800B0100 which isn't the one I'm seeing. You download the file here (362 MB). After running it says "Do you want to install the following Windows software update: Hotfix for Windows (KB947821)"

I also found a command line fix here:

net stop wuauserv  
net stop Cryptsvc  
ren %windir%\SoftwareDistribution sdold.old  
ren %windir%\system32\catroot2 crt2old.old  
net start wuauserv  
net start Cryptsvc

Update: I tried Moab's slightly longer command line fix (below) but that didn't work either.

Open an elevated Command prompt, type each of these commands one at a time, hit Enter key after each one, close cmd window when done, try Windows update again.

net stop wuauserv

regsvr32 /s wuaueng.dll
