WINDOWS Force Automatic Updates on WSUS

Forcing an immediate update detection via your local WSUS is a very handy thing to know how to do, and even more handy is the website that provides you with the cut-and-paste goodness to create your own update script in no time!

Visit http://msmvps.com/blogs/athif/pages/66375.aspx for all the low-down, but for quick reference, copy everything below the line into a TXT file and rename to .BAT or .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
