Using WSUS Offline as a Postinstallation Task (XP & Win7)


I got this working with XP and Win7 scripted installs and thought this might be useful for others. Basically, you use WSUS Offline to download all specified updates and then setup a postinstallation task on the K2000 to install them during a scripted install. The ultimate result is time and bandwidth saved.

In short, I'm using two different approaches for setting up a WSUS Offline postinstallation task, so you can take your pick.

For my XP scripted installs, I used dchristian's suggestion to copy the updates from the K2000's petemp folder (\\k2000\petemp) as a midlevel task (K2000 Boot Environment - Windows), but the driver feed workaround for 3.3 broke this. This wasn't an issue for my XP installs as I'm loading the drivers as discrete postinstallation tasks (i.e. not using the driver feed workaround), but something to be aware of as you read through the steps. The 3.4 update with the driver feed fix built-in may not have this issue, but I'm still on 3.3 so can't confirm. Once thing nice about this approach is that when the midlevel task runs you get a command prompt screen that shows all of the files copying over. When running the update postinstallation task, I had the best results running this after a reboot (see my other post for setting up reboots during a scripted install if you need the steps). Basically, I load the drivers, Office, IE8, WMP11, reboot, buffer for reboot, sleep, WSUS update, reboot steps again, then load 3rd party apps, etc. I have the WSUS update program set to autoreboot, so only use the buffer for reboot and sleep tasks following this. Without the autoreboot, the WSUS update screen just sits there and I didn't want to waste time trying to find a way around this.

For my Win7 scripted installs, rather than host the update files on the K2000 (since the midlevel task gets broken by the driver feed workaround), I have them saved to a folder on our file server. Since copying the files over takes a while, I found a way to use a compiled AutoIT script to give a progress bar during the copy proccess. It also authenticates to the file server, copies the files, and kick off the update program which actually installs the files (last step the same as the update program in the XP method, if you compare the scripts). I also have the WSUS update program set to autoreboot and have this set as the last postinstallation task. At one point during testing I had this in the same place as in the XP scripted installs (and it worked fine), but aesthetically I like having it at the end as it makes troubleshooting the rest of the scripted install faster as I can cancel the WSUS update process, reboot the target machine and troubleshoot the earlier tasks. This can definitely help as the WSUS update process can take a bit to complete.

As for the steps to get this running, here's my notes. The AutoIT script for the "self-contained" Win7 postinstallation task follows.

XP Scripted Install - Setup & WSUS Offline Postinstallation Tasks
________________________________________________________

1) Download wsusoffline (link directly under Most Recent Version on right side of page)
* http://download.wsusoffline.net/

2) Create a folder on the PC which will be used to download files and extract files here
* i.e. c:\wsusoffline

3) Create wsusoffline folder under \\ikbox\petemp

4) Create client-targeted folders under \\ikbox\petemp\wsusoffline
* i.e. xpsp3-o2k3sp3-ie8-wmp11
* optional step, can keep all updates in one folder if desired and just reference wsusoffline folder for rest of steps
* however, doing it this way keeps the amount of files copied to clients minimized
* doing this would require multiple runs of WSUS Offline, each time targeting different OS, etc and different target folder

5) Run UpdateGenerator.exe and select desired Windows & Office updates and options
* ex: Windows XP, Office 2003

6) At the bottom under USB medium check "Copy updates for selected products into directory" and specify target
* ex: \\ikbox\petemp\wsusoffline\xpsp3-o2k3sp3-ie8-wmp11

7) Click Start button to initiate downloads
* this will take a while to complete
* when completed, should see folder structure under \\ikbox\petemp\wsusoffline with UpdateInstaller.exe

8) Run UpdateInstaller.exe on target PC and review selections, make note of desired changes, then close
* ex: Install Office File Converters, Install Office File Validation, Automatic reboot and recall

9) Edit UpdateInstaller.ini to includue/exclude changes (per previous step)
* ex: instofc=Enabled, instofv=Enabled, autoreboot=Enabled

10) K2000 - During scripted install, copy the client-targeted folder to client.

Create a new Postinstallation Task - BAT Script - K2000 Boot Environment (Windows)

Name: WSUS - Copy Files (XPSP3-O2K3SP3-IE8-WMP11)
BAT Script:

@echo off
echo WSUS Offline Updates to Local Machine
Xcopy T:\wsusoffline\xpsp3-o2k3sp3-ie8-wmp11 c:\kace /e /y /k
wpeutil reboot

* added wpeutil line because wasn't rebooting following copy

11) K2000 - During scripted install, run Update.exe file via AutoIT script (wsusupdate.exe).

Create a new Postinstallation Task - Application - Windows

Name: WSUS - Install Updates
Runtime Environment: Windows
Command Line: c:\kace\wsusupdate-xp.exe

* changed from calling update.cmd via a batch script due to premature reboot during scripted install
________________________________________________________

XP AutoIT Script

* referenced in step 11
* compile this as wsusupdate-xp.exe and save to update folder
* i.e. \\k2000\petemp\xpsp3-o2k3sp3-ie8-wmp11
________________________________________________________

Run("UpdateInstaller.exe")
WinWaitActive("WSUS Offline Update 7.3 - Installer")
ControlClick("WSUS Offline Update 7.3 - Installer", "Start", "Button24", "left", 1, 40, 12)
Sleep(100)
WinWaitActive("DoUpdate /nobackup /updatercerts /updatedx /updatewmp /updatetsc /instofc /instofv /verify /autoreboot")
;waits until no instance of cmd.exe exists
ProcessWaitClose("cmd.exe")

Win7 Scripted Install - Setup & WSUS Offline Postinstallation Task
________________________________________________________

1) Download wsusoffline (link directly under Most Recent Version on right side of page)
* http://download.wsusoffline.net/

2) Create a folder on the PC which will be used to download files and extract files here
* i.e. c:\wsusoffline

3) Create client-targeted folder under \\fileserver\kace\postinstalls\wsusoffline
* i.e. win7sp1x64-o2k10sp1-ie9
* optional step, can keep all updates in one folder if desired and just reference wsusoffline folder for rest of steps
* however, doing it this way keeps the amount of files copied to clients minimized
* doing this would require multiple runs of WSUS Offline, each time targeting different OS, etc and different target folder

4) Run UpdateGenerator.exe and select desired Windows & Office updates and options
* ex: Windows 7 SP1 x64, Office 2010 SP1

5) At the bottom under USB medium check "Copy updates for selected products into directory" and specify target
* ex: assuming Y: is mapped to \\fileserver\kace -> use Y:\Postinstalls\WSUSOffline\win7sp1x64-o2k10sp1-ie9

6) Click Start button to initiate downloads
* this will take a while to complete
* when completed, should see folder structure under Y:\Postinstalls\WSUSOffline\win7sp1x64-o2k10sp1-ie9 with UpdateInstaller.exe

7) Run UpdateInstaller.exe on target PC and review selections, make note of desired changes, then close
* ex: Install Office File Converters, Install Office File Validation, Automatic reboot and recall

8) Edit UpdateInstaller.ini to includue/exclude changes (per previous step)
* ex: instofc=Enabled, instofv=Enabled, autoreboot=Enabled

9) K2000 - During scripted install, copy the client-targeted folder to client & run Update.exe via AutoIT script.

Create a new Postinstallation Task - Application - Windows

Name: WSUS Offline (Win7)
Runtime Environment: Windows
Command Line: start /wait wsusoffline-win7.exe

Note - Originally had this setup the same way as the XP install (with WSUS Copy as a mid-level task),
but this mid-level task broke the "driver feed workaround" in K2000 v3.3. Possibly might work
with 3.4 but will have to wait and see. Until then was able to get progress bar, etc working.

________________________________________________________

Win7 AutoIT Script

* referenced in step 9
* compile this as wsusupdate-win7.exe and upload to K2000
* be sure to update the network share credentials (DriveMapAdd - towards end)
* be sure to update the path to the WSUS update files (_CopyWithProgress - towards end)
