Windows Updates Reporting Tool

My firm uses MDT to build all of our computers. The windows updates are setup as packages so they can be applied to the OS before it is laid down on the PC. MDT will then download any new updates and apply them to the PC after the OS has been laid down. In order to keep track of new updates needing to be integrated as a package, I have written the following PowerShell script that will generate a CSV file listing all of the updates installed during the build and in the exact order they were installed. This gives a clean report of the updates instead of having to dig through the ZTIWindowsUpdate.log, which is what this report is generated from. I have integrated this script into the task sequence to execute immediately after the task Windows Update (Post-Application Installation). There are two parameters that need to be defined when calling the script. These are:

1. OutputFile - give the name of the file you desire such as BaseBuildUpdatesReport.csv
2. Path - Defines the location where you want the OutputFile to be written to

Here is an example of a command line:

• powershell.exe -executionpolicy bypass -file WindowsUpdatesReport.ps1 -OutputFile BaseBuild.csv -Path \\NetworkLocation\Directory

Here is a screenshot setting it up as a task sequence in MDT:
