You probably have a GPO that blocks updates directly from Microsoft. Did not check the WSUS server to see if the required packages were present. Simply made these registry changes and the PC was able to pull down the updates. Note, no need to undo these as the GPO will do it for you.

----- Below this line is the actual content to create your own .REG file -----

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\WindowsUpdate]
"DisableWindowsUpdateAccess"=dword:00000000
"DisableWindowsUpdateAccessMode"=dword:00000000
