# Register-PostPpkgTask.ps1 - register the "GE Shopfloor Post-PPKG" task.
#
# Called by Run-ShopfloorSetup.ps1 BEFORE the PPKG step (the PPKG reboot can
# kill the caller). Copies the runner out of C:\Enrollment (the bulk-enroll
# cleanup may remove staging folders) to C:\Program Files\GE\Shopfloor and
# registers a SYSTEM task that runs Invoke-PostPpkg.ps1 at every startup and
# logon until it has nothing left to do; then it unregisters itself.
#
# Idempotent: re-registering replaces the task.
