Hello,

I’ve seen this exact situation a few times after a WSUS rebuild, so you’re not alone. The error code 0x800F0954 is Windows telling you that the client is still trying to reach WSUS for “Features on Demand” (like .NET 3.5 or language packs), even though you’ve enabled the GPO to bypass WSUS. The catch is that the policy doesn’t always take effect right away, and sometimes WSUS registry settings override it.

Here are the steps that usually clear it up:

1. Double‑check the GPO scope: Make sure the “Specify settings for optional component installation and component repair” policy is applied to the OU where your Windows 11 clients live. Run gpresult /h report.html on a client to confirm it’s actually being enforced.
2. Force a policy refresh: On a client, run gpupdate /force and reboot. This ensures the bypass setting is active.
3. Check the registry: On a client machine, look under Mã HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
4. If you see UseWUServer=1, the machine is still locked to WSUS. Set it to 0 (or let the GPO overwrite it) and restart the Windows Update service.
5. DISM with source path: If you still hit 0x800F0954, you can install .NET 3.5 or language packs directly from the ISO or mounted media: Mã DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
6. Replace D: with the drive letter of your Windows 11 installation media. This bypasses WSUS entirely.

I hope this helps,
