Security Update (KB2920189) Installation fails with ERR 0x800f0922
If you are trying to install the security Update KB2920189 (or KB2871690) on a Windows 8 or Windows 2012 Hyper-V Maschine (maybe the problem only occurs on Generation 2 Hyper-V VMs), you will get an Exception with Errorcode 0x800f0922.
There are two ways to solve this:
- Disable UEFI Secure Boot
- Install the Bitlocker Feature
That’s it 🙂
