Windows Update (wuapp) switches - Are there any?

[straytoasters]

The topic pretty much say it all. This is geared toward Win7, but would equally correspond to Vista I suppose. So far I cannot find any switches for wuapp. I have tried some of the previous switches like "wuapp /detectnow" and even ran a few suggested rundll32 cmds, but so far the only thing I can get Windows Update to do via command line is to bring up the GUI, then I still have to click "check for updates" for it to actually do anything. I guess what I am wanting to know is what process run that makes Windows Update run automatic updates (which can download and install critical updates), or what switch/process is called when you click the "check for updates" in the wuapp panel? I have not seen a Windows Update/wuapp reference in the scheduled tasks.

Basically I am wanting to set up an AT command that will run Windows Update, but I dont want to set Windows Update to run automatically on its own every night. Thoughts/Suggestions?

To find cmd line switches inside exe/dll files I use grep.exe with string.exe and a bat file like so:

@echo off
setlocal enableextensions
for %%a in (a b c d e f g h i j k l m n o p q r s t u v w x y z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 1 2 3 4 5 6 7 8 9 0 - / \) do strings.exe %1 | grep.exe -i %%a>>%1.txt

These are some of the results
