Error Code 0x800F0954 on Windows 10

I was installing .NET Framework 3.5, denied with an error message saying “Windows couldn’t complete requested changes. Error Code 0x800F0954 “.
How to fix it?

It really works with the registry update and only restarting the update service.
Because some times when you are in a domain group policies will automatically update the registry entries
when you restart the machine.

Thanks

I know this topic has an accepted answer, but I wanted to add one thing which may benefit others who try the accepted answer (changing the WSUS reg key) and find that it doesn't work. In my case, I had to run dism /online /cleanup-image /startcomponentcleanup /resetbase, and sfc /scannow, reboot, then my issue was resolved. I wasn't trying to install .NET, but was trying to install just a basic Windows feature - Chinese Simplified Voice. I received the same error code (which led me to this post) but for a different reason.

Hi,
You could try the following method.
Temporarily bypass WSUS server using the following registry edit (requires administrator privileges).

Right-click Start, and click Run

Type regedit.exe and click OK

Go to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

In the right-pane, if the value named UseWUServer exists, set its data to 0

Exit the Registry Editor

Restart Windows.

Hope above information can help you.

Thanks for the tip!

Instead of restarting, it is sufficient to restart the Windows Update service

I wouldn't recommend restarting windows was causing the GPs to reapply the 'UseWUServer = 1'. Instead after setting the value to 0. restart the WUAUSERV service and this should fix your issue!

This workaround was the answer for me, thank you! Did not have to reboot PC after making the registry change.

Since the URL is no longer valid and must be loaded archive.org to view its content, I'm posting it here for future reference as this is extremely useful.

Here is the link I obtained it from as the copying pasting of the content renders the images useless.

The 0x800f0954 error is that a WSUS server is in place without the packages needed to install this .NET 3.5 add-in.

The workaround is relatively simple:

Stopping the Windows Update service (command window)

net stop wuauserv
Then, edit the registry (via Regedit)

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
Change UseWUServer that is 1 by 0

Restart the Windows Update service

net start wuauserv
Start the installation of the .NET 3.5 module

Once installed... we start again.

net stop wuauserv
Then, edit the registry

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
Change UseWUServer that is 0 by 1

Restarting the Windows Update service

net start wuauserv
There you go!

Obviously... it also offers an alternative to bypass the WSUS for other updates....

Thanks for the note on the simple net stop command.

I prefer to use Powershell to make my life easier, so in an elevated Powershell I ran this and was able to get past the dreaded 0x800f0954 error.

net stop wuauserv; ` Set-ItemProperty HKLM:\\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU -Name UseWUServer -Value 0; ` Add-WindowsCapability -online -Name Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0;

As a bonus I didn't have to restart the service before the command succeeded and I was also able to run Update-Help without getting any errors.

I may turn the update service back on eventually, but since this is a W365 VM managed by IT, I'm sure they'll restart it and force it on again eventually.

I found that each windows feature installation will automatically reset UseWUServer value to 1.
So I changed the UseWUServer value to 0 , 3 times and reboot 3 times, to finish adding a language package (Basic Typing, Hand Writing,& Speech).
