Answer

stop the Windows Update service (net stop wuauserv) before installing a MSU update. I use this cmd:

@ECHO OFF
SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
FOR /R "%~dp0" %%A IN (*Windows6.1-KB*.MSU) DO (
        CALL :SUB %%~nA
    ECHO= Installing KB!KB_NUM!
    >NUL net stop wuauserv
    WUSA "%%A" /quiet /norestart)
ECHO= == Press any key to close the Window ==
>NUL PAUSE
GOTO :EOF
:SUB
SET "KB_NUM=%*"
FOR /F "DELIMS=-" %%B IN ("%KB_NUM:*-KB=%") DO SET "KB_NUM=%%B"

to enum all MSU updates in the folder where the CMD is stored and install them and before installing an update, it stops the service to speed it up.
