But before going forward, a little warning is required. Now to fix this one, the steps are simple, first remove all IE11 components and reset the IE feature.

Which would explain why Windows Update tries to install it again. But IE 11 wasn’t listed in installed updates.

I’ve tested IE on several affected servers, and on everyone of those servers, IE worked as expected. A plausible cause (at least to me 😉 ) seems to be, that the update process failed at the first installation attempt, but didn’t revert the changes. I tried them all, and this doesn’t fix this specific issue. I couldn’t find a good fix for this specific issue on the internet, most technet articles advise to reset windows update. NET 4 and a couple of other updates from being installed. That last part is a bit weird, it also blocked. Hiding the update isn’t an option, because this would also block security updates to IE and some other updates. The corresponding eventlog with error 0x80070643 is: The really odd thing about this failure to install was, that IE 11 was already installed on the system: They failed with the following error:Ĭode 9C59 Unkown error, those are always nice. A number of servers on several different locations had problems with updating. I was encountering an issue whilst updating some 2008R2 servers using WSUS.
