Windows 10: Hyper-V Won't enable "Error code: 0x80073701" (Windows 10 Pro on AMD CPU x64-based),...

(1) Hyper-V Won't enable "Error code: 0x80073701, missing assembly code" (Windows 10 Pro on AMD CPU x64-based).


(2) I followed suggestion from this site, and checked the C:/Windows/CBS/CBS.log. It points to error when "exec resolving" KB4483234


(3) I checked my PC update history, KB4483234 is not there.


(4) I looked up KB4483234 on Microsoft web site, it was released December 2018 and was part of KB4477137.


(5) I can see KB4477137 in my PC's update history.


(6) Microsoft web site's article suggested me to re-install the KB4477137 through Control Panel/Check Updates. But I cannot: neither be able to install it nor uninstall it, probably because multiple updates applied after this update. The "uninstall" button just not show up for this update in Control Panel.


(7) Is there a way I can fix this problem and enable Hyper-V?

Hyper-V Won't enable "Error code: 0x80073701" (Windows 10 Pro)

I have Windows 10 Pro along with an AMD 8350, 8GB of ram, and meet all of the requirements for Hyper-V Requirements (used the systeminfo command and shows all as yes). Every time I go to enable it it spits out "The referenced assembly could
not be found. Error code: 0x80073701"

Have a look at
How to resolve the error 0x80073701(ERROR_SXS_ASSEMBLY_MISSING) when you are installing a service pack or update

You might be missing a service pack or functionality



Check the above and see if you have all the Hyper-V features turned on like my system.

Have you checked you bios for everything set correctly read

Virtualization disabled in BIOS

Try setting up in power-shell

Virtualization: Create Hyper-V Virtual Machines with Windows PowerShell

Your system info output is significantly different

 

Hyper-V Won't enable "Error code: 0x80073701" (Windows 10 Pro)

I have found that Hyper-V is broken when removing Virtual Box, because shared files are wrongly removed in the un-install. I tried to enable Hyper-V under
10240/TP build 10532 Win 10 Pro and it failed.

These errors are all recorded in the Windows Feedback

for Win 10 Pro

I switched off, unticked, all the Hyper V Features off on my current release TP 10525.

The features were removed and restarted. Next I enabled, ticked the boxes and the files were searched and features installed. The restart saw the screen reconfiguring Hyper-V to 30% then restart, continued to78% stalled then finally go to 100% and restarted.
Now Hyper V back and I can run the VS2015 community RC Android emulator again. During the start-up/install of VS 2015 RC the Hyper-V is check for all the functionality of emulator.

I cannot go back to build RTM 10240 Pro for technical reasons

Have you tried search box or the Hyper-V client download maybe the missing files are loaded
