Patch Current WIM Files

ConfigMgr

When we started offering up patch current WIM files last year, we were trying to eliminate the time needed for patching during a deployment.  In beginning this process, I quickly wrote out a script to do what I wanted, and then put it away until the next month.  Each month it became a little more refined and easier to use.  Now I can kick off a couple VMs, run the script and a few hours later (depending on your anti-virus) have patch current WIMs the day after Patch Tuesday.

I have read many blogs on the subject and while they may not have had an all-in-one answer for me, I have taken pieces from everyone for what I was trying to do.  If I am using something you wrote, thank you.  I’ll have some acknowledgements at the end of the article.

Due to having to use a proxy, I cannot automate the gathering of the updates, but if you can, you can easily add that to this process.

First, we have a network share that keeps everything.  Different directories for OEM files, monthly patches, Upgrade packages, and reference WIMs.

 

Once 1803 came out, I saw that I needed to make this more dynamic for future releases.  To accommodate this I have a couple of questions based on which version you are editing, such as 1709, 1809, etc.  We also maintain different languages, so you would enter en-us or another language if needed.

$OSVersion = [Microsoft.VisualBasic.Interaction]::InputBox(“Enter Windows 10 version `n (Example 1809 = 17763) `n 1709 = 16299 `n 1803 = 17134 `n 1809 = 17763”, “Windows 10 Version”, “16299”)

{

Write-Host “No Production Media Value Entered”
Exit
}

#######################

The Create Production Media section above will create an SCCM Operating System Upgrade package for you if you select “true” when prompted.

Next, it is important to place your network shares correctly.  The naming convention I use for $0Source for the OEM WIM makes sense to me, but may not make sense to you, so update accordingly.

#########

Function DownloadSource {

Write-Host “Copying WIM File” -ForegroundColor Yellow
$TimeStamp = Get-Date
Write-Host “$TimeStamp” -ForegroundColor Cyan
$copysourcedir = “\\server.com\source_directory”
$0Source = $OSVersion + “.0source_” + $Language
$OEM = (Get-ChildItem $copysourcedir -Directory | select-string -Pattern ($0source) | Sort-Object -Descending | Select-Object -First 1)
Write-Host “Copying $Language source files for Windows 10 $OSVersion” -ForegroundColor Yellow
copy-item $copysourcedir\$OEM\sources\install.wim $PSScriptRoot\$OSVersion\$Language\install_$Language.wim -Verbose

$TimeStamp = Get-Date
}

##########################

That will copy the WIM file to where you are running the script from.  It will create directories based on built number and language.

The next function is just a cleanup if the directories already exist on your system from a previous month.

##############

Function Cleanup {
Try {
Write-Host “Cleaning Up” -ForegroundColor Green
if (Test-Path -path $PSScriptRoot\$OSVersion\$Language) {Remove-Item -Path $PSScriptRoot\$OSVersion\$Language -Force -ErrorAction Continue}
& DISM /Cleanup-WIM
}
Catch
{
Write-Warning “Cleanup failed”
Throw $Error
}
}

################

After the functions are setup, we next start logging and check on a few items.  If ADK is not installed, it will exit out.  If the mount directory does not exist, it will create it.

########################

The next section will copy the updates that are being used to update the WIM, including any CU (I put flash and .net in the same folder) SSU or Dynamic Updates. It will look for the newest folder for the CU patches or the naming convention I have set up below.

copy-item $PatchSource\$PatchDir\* $PSScriptRoot\$OSVersion\$Language\DU -Recurse #-Verbose

###########################

Now we call the download function from above and download the OEM WIM file.  We then compare the WIM version versus the ADK installed in order to use the correct or newer version to modify the WIM file.

#################

#Download Source files

Write-Host “Windows ADK is not correct version to modify WIM.” -ForegroundColor DarkRed
Exit
}
else
{Write-Host “Windows ADK $result and WIM Version $WIMVersion” -ForegroundColor Yellow

#################################

NOTE: If copying each section instead of downloading the script, that there is an open bracket at the Write-Host that continues below.

We now extract the WIM.

##################

Next we just mount the WIM.  Timestamps if you want to see how long you were bored.

###################

Now we simply patch the mounted WIM with the Servicing Stack, CU, and any Dynamic Updates.

}

If ($EnablePause -eq “True”) {
pause
}

####################

This is where the pause is in the script if enabled True.  This allows you to check the for whatever reason you may have.

Next we reset the base and cleanup the WIM.

And simply unmount the WIM.

$TimeStamp = Get-Date
Write-Host “$TimeStamp” -ForegroundColor Cyan

#####################

Now, if you said “True” for create production media it will first update your MDT with the WIM file.  (If you do not create reference images, you can eliminate where needed.)

And that’s it.  I had to clean it up a bit in order to share, but those are the main steps and processes.  I will probably come back and add to it as I add more items.  Including replicating out to a DP group as part of the process.  I have hesitated as our SCCM guys don’t like when we replicate WIMS without checking site replication backlog first.

Feel free to contact me and comment or suggest as you want.

Thank you for reading this far.

My name is Scott Graves, I have been doing IT since 1995 and am currently heavy into OSD, Task Sequences and Upgrades.  I have set up a Twitter (@shotgn22) if you have any questions.  Thank you Adam Gross of ASquareDozen.com and Chris Buck of this page. Dave Segura of OSD Builder, Mike Terrill, Gary Block, Michael Neuhaus and many others are sites I visit regularly.  Without them, I wouldn’t have been able to automate what  I have thus far.  That said, this works great for my situation, and I know everyone has different environments and situations, but I hope that if anything, there is something I have used above that makes the “ding” go off and helps someone out.
