# Configure-PC.ps1 - Interactive tool for SupportUser to configure a
# shopfloor PC after imaging. Two sections:
#
#   1. Machine number - if UDC/eDNC are still at placeholder 9999, prompt
#      to set the real number right now.
#
#   2. Auto-startup items + machine-number logon prompt - toggle which apps
#      start automatically for all users, and optionally register a logon
#      task that prompts STANDARD users for the machine number if it's
#      still 9999 when they log in (for the case where SupportUser skips
#      it here and the end user needs to set it themselves).
#
# Startup .lnk files go in the AllUsers Startup folder:
#   C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\
#
# Run via Configure-PC.bat on the SupportUser desktop.
