Aarrgghh – why don’t I remember these things anymore????
I was in the process of firing up a new 2012 R2 VM, and in my rush, I clicked to download and install all updates before heading out to do some errands. When I got back home, I was greeted with the following error message:
We couldn’t complete the updates. Undoing changes. Don’t turn off the computer.
The thing is — this was a known issue over a year ago! One that my good MVP friend Boon Tee encountered it, and wrote up a blog post at that time for the workaround.
The problem occurs if you are creating a Gen 2 virtual machine (.vhdx) and KB 2920189 is included in the list of updates you are trying to install.
Shutdown VM –> disable Secure Boot from the VM –> Start VM and install updates –> Shutdown VM –> re-enable Secure Boot –> Start VM
You can find the option to enable/disable Secure Boot under the Firmware section of the VM settings.
Warning — the “Undoing changes” can take quite a long time to complete. I decided to delete the VM, and start over from scratch!
