"Update Now" Switch To Use With WSUS

Thursday, 17 November 2005 by Michel Roth

On of the things I missed from SUS was the abillity to select a (SUS) client system and have some kind of "Update Now" button to update on demand, from your local SUS-server.

Within WSUS there's is an option to this. This is because of the new /detectnow switch. KB555453 details on this in a cmd file:

Copy and Paste the code below into a text file and name it AUForceUpdate.cmd
====================================================
@echo off
Echo This batch file will Force the Update Detection from the AU client:
Echo 1. Stops the Automatic Updates Service (wuauserv)
Echo 2. Deletes the LastWaitTimeout registry key (if it exists)
Echo 3. Deletes the DetectionStartTime registry key (if it exists)
Echo 4. Deletes the NextDetectionTime registry key (if it exists)
Echo 5. Restart the Automatic Updates Service (wuauserv)
Echo 6. Force the detection
Pause
@echo on
net stop wuauserv
REG DELETE "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v LastWaitTimeout /f
REG DELETE "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v DetectionStartTime /f
Reg Delete "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v NextDetectionTime /f
net start wuauserv
wuauclt /detectnow
@echo off
Echo This AU client will now check for the Updates on the Local WSUS Server.
Pause
