Hi
Had no Error code, but was warned by german site ComputerBild ( Windows 7 update blocked ) on 05-12-2017, then tried to start WU: WU didn't even run and I had to abort it in task manager. Date back to 02-12-2017, set to manual WU, unchecked "updates fore other MS products", tried again, and then WU worked, got updates released even after 02-12-2017, with the fixed authcab.cab file, but check box for other MS products was lost. Set microsoft.com in IE compatibility tools, went to borncity.com.... as above, and re-installad MS Silverlight albeit I had the last version installed in June 2017. Very strangely, Silverlight size was over 700 MB before, and now 50,7 MB in installed programs (buggy installation ?). Lost check boxes return in WU and all works fine.
Was not aware of the need of MS Silverlight for WU and MSUpdate running trouble-free.
Wonder what happened without these manual fixes, why that mess ?
Thanks for your help.
