I was busy the last few days creating a task sequence inside the Microsoft Configuration Manager (Config Mgr) or also known as SCCM in the past, where we remove the config mgr agent after the task sequence is finished. Sounds easy right? Well I thought so too, but it wasnt as easy as run ccmsetup.exe /uninstall as a command line argument.

What does not work

  1. I tried to run ccmsetup.exe /uninstall as a command line argument. In WinPE and full OS mode.
  2. All other forms of running the ccmsetup.exe /uninstall command inside powershell scripts.
  3. I found this script which kind of worked but it left a lot of remnant files in C:\Windows. Additionally the task sequence breaks directly after execution.

What did work

The cleanest way to remove the agent from the computer at the end of the task sequence is to use the build-in Prepare ConfigMgr Client for Capture method.
