Revert "Replace Windows PowerShell with PowerShell"

[sdwheeler]

Reverts #2776

I changed the target to staging because the file changes were appropriate to v6. However, this pulled in changes meant for 6.1. We don't want to publish those v6.1 changes yet.

@it-praktyk Can you resubmit your changes to the staging branch?
