ERRCODES - 0x800f0954

Try this first, CMD as admin with ISO mounted on D:

Add-WindowsCapability -Online -Name NetFx3~~~~ -Source D:\sources\sxs

As a temporary workaround, change the registry key “UseWUServer” to 0. It is located at:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

Reboot is required
