Server 2016 Updates failing to install

  • 772

2019-04 Cumulative Update for Windows Server 2016 for x64-based Systems (KB4493473)
2018-09 Update for Windows Server 2016 for x64-based Systems (KB4091664)

Four failures to install on one particular server but have installed all of them on another 2016 box.
ESET File Security installed.
Server has been rebooted multiple times.
I've also tried purging the %windir%\SoftwareDistribution\DataStore folder to no avail.

Is anyone else having these problems? I can't seem to find much info online.

  1. I would also suggest purging the %windir%\SoftwareDistribution\Download\ folder as well. Sometimes there can be a bad or partial download in there that the update is trying to use.

  2. Following the disastrous removal of a single Windows Update, and the following disastrous attempt to recover, I've had to rebuild the server from scratch. Luckily the rebuild has resulted in the Windows.old folder so I can recover information from there.
