Hi MM. Mr Kywildcat and Vegan Fan,
GOOD NEW ! At this time, my issue is solved. The only black side is "how ?" : I hope that we will get a response some day ; however, and for in information pnly - hoping this could help someone - I resume some actions which allowed this the happy end
:
1) about installing 8.1 : I wanted to be sure that gain/pain ratio was positive, and that upgrading from a (potentially) damaged system would'nt produce something looking like a new Win 8.1, but difficult to maintain and keeping some negative potentialities.
2) I was influenced by the fact that this
0x800F0922 error acted as "a serial killerror", whose root cause could be a unique update error at reboot time concerning several (>20) packages, so I decided to test some manual upgrades.
3) Manual update (i.e. manual download and maunching of .msu packages) of the 2 following packages
(whose update previously failed on a Windows Update) was successful : .NET Framework version 3.5 for x64 (KB2898866) and Camera Codec Pack Windows 8 for x64 (KB2899190)
4) So I decided to try Windows Update on a selection of packages, first : those concerning .Net Framework 3.5 and 4.5 (that is: KB2898866, 2901120, 2898865) --> Successful !
5) finally, I selected almost all other packages, with some exceptions wich I (think to) have no need for : KB2871690, 2904659, 2843630. To be complete, here is the list of pakages updated one time at all :
KB 2892074, 2893294, 2893984, 2909210, 2912390, 2916036, 2889784,2903938, 2911101, 2913152, 2917499
--> always succesful.
I am not a specialist, but I uess that this 0x800F0922 error hides another problem which is globally "H-RESULTED"
to all updates pending in one update operation with reboot. This could be assumed from this CBS.log exterped from my last wrong attempts, where root cause seems not to be
0x800f0922, but 0x80004003 :
2014-02-15 21:29:13, Info CBS Could not get active session for current session file logging [HRESULT = 0x80004003 - E_POINTER]
2014-02-15 21:29:13, Info CBS Not able to add pending.xml.bad to Windows Error Report. [HRESULT = 0x80070002 - ERROR_FILE_NOT_FOUND]
2014-02-15 21:29:18, Error CBS Startup: Failed to process advanced operation queue, startupPhase: 0. A rollback transaction will be created. [HRESULT = 0x800f0922 - CBS_E_INSTALLERS_FAILED]
Anyway, thanks to you who spent some of your time to describe issues and search/ suggest solutions ; I will upgrade my system to 8.1 anyway, some of this day, when I am sure that my configuration does not hides some other problem. I thing that potential
issue remains until maybe a new KB corrects it, wrong :-) ?
And I hope that you - Mr Kywildcat - can upgrade your system on "current levels" trying similar attempts.
Phil
