Windows 8.1 Installation, Setup, and Deployment I made a boot usb from another win 8.1 machine and using tools to do the repair did not work. I am now trying the long way starting with diskpart an bootfix. Hello, i would like to update this Windows 8.1 installation to Windows 10. It is hosted as a VM inside Parallels Desktop 14 on a MacPro5,1 with MacOS 10.11.6.

You can remove the /Source tag and let it search against the microsoft servers for component corruption.

This is why a lot of members are going to recommend against doing an OS upgrade, especially on servers, unless it's absolutely necessary. Is there a common theme to what is causing server manager and the BSODs, or are we looking at multiple issues?

Dism Error 0x800f0906 Server 2016

The other option for the KB you mentioned is you can probably open the .exe and pull out the .cab file and manually install it with a DISM call to bypass using a wusa call for it.
