Windows 7 Windows update error 0x80070BC9 with windows 7

[Pandino_cz]

Hi,

I have only one Windows 7 machine which has started to show 80070BC9 in Windowsupdate.log file when trying to install Windows updates KB2478662. I believe this refers to a "pending update" which needs to be completed before other updates can follow (normally after a reboot).

I restarted the computer many times, tried to install this update manually, tried .Net cleanup tool, strated the computer in selective startup mode (without load startup items) and reset Windows update components. unfortunately I still have the same problem.

I get the following in Windowsupdate.log file:

It's very important for me to fiind a solution without reinstalling Windows 7.

Your help would be very much appreciated.

Thanks a lot,
William
