my name is Marcus and I am a Microsoft PFE working in Germany. I provide support for Microsoft customers primarily regarding Identity and Security. I also do PowerShell workshops.

During my work at customer sites I often see administors doing the same manual tasks on a daily basis. That’s where the ideas for most of my PowerShell samples come from.

If you find some of my scripts usefull, feel free to drop me a note. And if you are confronted with boring daily tasks that you like to be automated, tell me what you need and I might have a code sample that helps you.
