You are correct, I made a typo in that issue nr. I had it correct it the topic title

. I edited my posted above to show the correct nr.
I have downloaded the installers for the patch via the links you provided, and then ran them by hand
KB2705219 still fails. I don't think it gives a reason on screen but it flicks by rather fast. Is there a log of this somewhere?
KB2786400 seems to go alright. It finishes without an error and tells me I have to reboot which I will do after posting this.
I grabbed the installer for KB2773072 from
Download Update for Windows 7 for x64-based Systems (KB2773072) from Official Microsoft Download Center
Running this seems to go fine as well, asking for a reboot.
That suggests only a remaining issue with KB2705219, which I apparently have for quite some time already, as this one from October 2012?
I'll reboot and report back with the results from Windows update.
