Howdy. I’ve been spending the past month or so automating a lot of repeatable tasks, none of which have been groundbreaking. Yet, I don’t want to leave you hanging, so I thought I’d share a quick PowerShell script I created to initiate a deployed Task Sequence on a client machine. It is a nice tool to keep in your utility belt and you can use it to automate any deployed application that may appear as available in Software Center.
The script syntax is:
Execute-TaskSequence.ps1 -TSName <TSNAME>
Obviously, the TSName can be edited to an Application name, but I needed this specifically for a project that needed to automate the initiation of a Task Sequence. Stop yelling at me.
This will initiate a Machine Policy Evaluation and Retrieval a maximum of five times (15 second intervals) before it aborts, just in case you ran the script but forgot to deploy the TS or add the machine to a collection. It will stop requesting policy once the TS is found.
