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%system32catroot2 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

rmdir %windir%softwaredistribution /s /q

rmdir %windir%system32softwaredistribution /s /q

regsvr32 /s wuaueng.dll

regsvr32 /s wuaueng1.dll

regsvr32 /s atl.dll

regsvr32 /s wups.dll

regsvr32 /s wups2.dll

regsvr32 /s wuweb.dll

regsvr32 /s wucltui.dll

net start wuauserv

Couple things to check/try:

1) Ensure the RPC (Remote Procedure Call) Service is enabled (automatic) and running.

2) Destroy and rebuild your WMI repository. To that end, perhaps check out The WMI Diagnosis Utility from Microsoft.

Reinstall the Windows Installer

Then run this commands to clear update list, restart services, and re register DLL files.

Open a command prompt with Admin rights: click on Start, type cmd, on the results right click on Command prompt, and select Run As an Administrator.

Try the following step by copying & paste following into the command prompt:

ipconfig /flushdns

GRC's "Never 10" is designed to straighten-out the messy windows 7 updater, and then disable it's Windows 10 upgrade suggestions.

It was found that even after Microsoft turned off the "nagware", that Steve Gibson's program was still getting downloaded all the time - due to a happy co-incidence that it fixes the dreaded windows installer errors, as part of it's process.

I have run this app many times with 100% success to fix the 706be error, among others (searching for updates forever is another common one caused by the same thing). If you want Windows 10 later, you can still upgrade it - "Never 10" just disables the automatic pestering.

edit: sorry, to answer your direct question as to the cause, without going on a rant: it was caused by a patch to a file, and then a subsequent patch which had the older version of the file, and then the Cumulative-Update-Roundup (a group of several fixes in one patch, like a small service pack) which included both of the previous clashing "fixes". The same thing happened again in Windows 10, unfortunately, you PC was just one of the ones that got caught in the "perfect storm" .
