# 05-OfficeShortcuts.ps1 - Public desktop + Default User Start Menu shortcuts for
# the core Office apps (Excel, Word, PowerPoint).
#
# Only runs if Office is actually installed - self-detects via EXE existence so it
# silently no-ops on PC types whose ppkg didn't include Office (Display kiosks,
# Wax/Trace, etc.). Office Click-to-Run installs the binaries but doesn't create
# desktop shortcuts; this script fills that gap.
#
# Shortcuts land in two places:
#   - C:\Users\Public\Desktop\           - visible to all users immediately
#   - C:\Users\Default\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\
#                                        - inherited by every NEW user profile
#                                          (Azure AD logons after the device is
#                                          enrolled)
#
# Idempotent: overwrites existing .lnk files each run.

# Office binary location varies by install type and version:

# The standard ShopFloor Office ppkg is x86 Click-to-Run so normal case
