WUAUCLT /detectnow - VBS and GUI methods

So, how do you force the update detection? In this blog entry, let's take a look at some of the techniques.

  • Rob Dunn [WSUS MVP] has created this simple script to force remote computer to perform wuauclt.exe /detectnow using object methods. That's cool Rob - Thanks again.

' ---------------START CODE---------------
strComputer = inputbox("Enter a computer name to run WUA detectnow","Invoke detectnow")
if strComputer = "" then wscript.quit
on error goto 0
Set autoUpdateClient = CreateObject("Microsoft.Update.AutoUpdate",strComputer)
AutoUpdateClient.detectnow()
wscript.echo "All done."
' ----------------END CODE-----------------

  • For all GUI fans, take a look at WSUS - DETECTNOW 2.0 from WSUS.de. With this GUI Tool, you can trigger detection for approved updates and can reset SusClientId too.

# re: WUAUCLT /detectnow - VBS and GUI methods

I use AUForceUpdate.cmd and run it remotely against machines using PSEXEC from sysinternals.com like so:

psexec \\computername -c AUForceUpdate.cmd

- which copies the CMD file to the computer and then executes it. I even wrote a batch file that does this will all of my company's XP boxes in one swoop.
