MDT Build Application Report One-Liner

While building a new reference image, I always want to make sure every application got installed before the WIM is generated. I have done this in the past by placing a pause in the build immediately after the windows update post-application installation is completed. It definitely takes time for me to go through the list of apps and verify they are there.

While researching the process, I found the ZTIApplication.log file that is generated during a build. It contains the list of all applications and the return code after the install. I wrote this script that will query that file and generate a report of all installs so that I can quickly look at the list to make sure everything is there before continuing with the WIM file generation. One thing I did have to do is to move some Run Command Line tasks to application tasks so they would be in the above-listed log file. 

This was all achievable with a PowerShell one-liner that can be executed in the build via a Run Command Line task as shown below. 


When the one-liner executes in the task sequence, it will generate a report as shown below. The report also pauses the build until you click OK giving you time to review the report and possibly install something that may have failed. 



Below is the one-liner you can copy and place in the task sequence.

 powershell.exe -executionpolicy bypass -command "&{$Apps=@();$ZTIAppsLog=Get-Content -Path ($env:SystemDrive+'\MININT\SMSOSD\OSDLOGS\ZTIApplications.log');$AppNames=($ZTIAppsLog|Where-Object {$_ -like '*Name:*'})|ForEach-Object {(($_.split('[')[2]).split(':')[1]).split(']')[0].Trim()};Foreach ($App in $AppNames) {$obj=New-Object -TypeName PSObject;If (($ZTIAppsLog|Where-Object {$_ -like ('*Application'+[char]32+$Application+'*')}|ForEach-Object {($_.split('[')[2]).split(']')[0]}|ForEach-Object {$_ -replace 'Application ',''}) -like '*installed successfully*') {$Status='Installed'} else {$Status='Failed'};$obj|Add-Member -MemberType NoteProperty -Name Application -Value $App;$obj|Add-Member -MemberType NoteProperty -Name Status -Value $Status;$Apps+=$obj};$Apps|Out-GridView -PassThru}"
