https://support.microsoft.com/en-us/kb/2872074 I realized that IE11 installation shouldn't be the cause, but other missing updates..
These are the missing updates reported by WU (and WUMT, etc.. too):
- KB2871997 Aggiornamento della protezione per Windows 7 (KB2871997)
- KB2872339 Aggiornamento della protezione per Windows 7 (KB2872339)
- KB3004375 Aggiornamento della protezione per Windows 7 (KB3004375)
- KB3031432 Aggiornamento della protezione per Windows 7 (KB3031432)
- KB3033929 Aggiornamento della protezione per Windows 7 (KB3033929)
- KB3045999 Aggiornamento della protezione per Windows 7 (KB3045999)
- KB3046269 Aggiornamento della protezione per Windows 7 (KB3046269)
- KB2882822 Aggiornamento per Windows 7 (KB2882822)
- KB3068708 Aggiornamento per Windows 7 (KB3068708)
- Internet Explorer 11 per Windows 7
while these are the missing updates according to the article
Troubleshooting a failed installation of Internet Explorer 11 (

MANDATORY FOR IE11
- 2729094
- 2731771
- 2533623
- 2670838
- 2786081
- 2834140
OPTIONAL FOR IE11
- 2639308
- 2888049
- 2882822 (this is the only one in the missing updates WU list, too)
Well, I can't install both the two groups of missing updates (the first, WU one, and the second, IE11 required ones). So I deduce that the origin of the problems is that I can't install these updates, no one of them!
If I try to install the first group through WU (or WSUSOU) they seem to be installed but after Windows restart they re-appear (because of failure installation/finalization during Windows restart?).
If I try to install the second group manually, for each one I get the same error message that says it's not possible to install.. why??
Is there a way to investigate why I can't install updates?
