Calling function in a Parallel foreach loop

[sekou2331]

I know start-sleep. I mean how would I use that in the in the parallel code?

Just add it to the end of the remote code block.

Ok thanks. Last question If I run in parallel a trigger to run a schedule task on a remote computer that calls a MSI to install will this have the same issue of dying before completed?

Yes. The installer woks that way. Without waiting the session will terminate on most MSI installs before the install is complete. You must wait in the session until the install is complete.

You can use ConfigMgr from DSC to ask the remote OS to fully manage and maintain the install.
