Error with Windows Update KB3000850

For more detail I would use the ReportingEvents.log to get the timestamp.  Then find the portion of CBS.log which corresponded to that.  It might give a clue about which module is "missing".

Hello Robert,

thanks for this great hint!

Checking CBS.log revealed that KB3000850 is picky about the structure of the start menu...

I had moved several entries to a sub-directory:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessibility

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Tablet PC

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\System Tools

It is easy to spot these errors in CBS.log: search for ", Error" without the quotes (the comma space in front is important).

After recreating these three directories I was able to install KB3000850 :-)

Thanks again & greetings from Germany,

Uwe

AlResnick, if I were you I would not install it.

It will freeze your Windows 8.1.

I have the same problem on two computers running Windows 8.1 x64. Both give exactly the same error message in Event Viewer (except for the 'User', obviously).

They both get to the end of the update and then say failed. I have tried using the stand alone installer as well. Here is the output from Event Viewer from one of the computers:

Any help please?

Robert,

Thanks for your quick reply.

Well, I ran DISM and it fixed whatever it needed to (sorry can't recall the exact wording).

I then rebooted and tried to download and install this update again -- got same error.

No joy -- any other ideas?

 got error 800700002 when I tried to install this windows update.

Probably indicates that there is WinSxS corruption.
