Retriggering TaskSequence remotely on Windows Embedded devices (ThinClients)

Question

Hi,

I have a requirement to retrigger Task Sequence on windows embedded devices (Thin Clients) on demand. I was hoping to achieve this using a PS script combined with CMScript feature available in MECM. CMscript be design runs in local System Context

This task in itself comprises to 2 subtasks:

1. Disabling UWF filter followed by restart (wrote a PS to do this and works well with CMScript)
2. Re-trigger the OSD Task Sequence once UWF is disabled (unable to get this to work in System Context with or without interactive user logon)

Have tried approaches in the below links but it did not work when executed as system user. As a domain admin, it works fine

• https://timmyit.com/2017/01/09/invoke-osd-task-sequence-remotely-with-powershell/
• https://msendpointmgr.com/2012/11/21/re-run-task-sequence-with-powershell/
• https://msendpointmgr.com/2019/02/14/how-to-rerun-a-task-sequence-in-configmgr-using-powershell/

Has anyone had any experience with such scenario?
Any suggestions to how to get this work with system account?
Any documentation from MS sat ng system accout + ps approach will not work/not supported for Thinclient to retrigger TS if anyone is aware if of?

Thanks!

Hi Hanhunzgu, thanks for responding.. but don't want to create a new TSK to trigger an existing TSK on the machine.

Do we know if retriggering TS using Powershell in system context is not supported by MS for embedded devices (Thinclients)?

Hi,

For this issue, perhaps we can try to use the "Run Task Sequence" step to select the OSD task sequence to run after disabling the UWF script and restarting the computer.
Like the screenshot below:

For more details about the step, please refer to this article:

Hope this thought can help you.
