The driver check - the most valuable check in this script - has never actually
run. It died on:
Driver check failed: Cannot convert the JSON string because a dictionary that
was converted from the string contains the duplicated keys 'FileName' and
'FileName'
HardwareDriver.json carries both casings of the same fields - fileName and
FileName, destinationDir and DestinationDir. ConvertFrom-Json treats object keys
case-insensitively and refuses the document. -AsHashtable would handle it but
that is PowerShell 6+, and WinPE runs 5.1. Confirmed it throws on PowerShell 7
too, so no version of ConvertFrom-Json can read this file as-is.
Pulls the four needed fields out of each entry by regex instead, preferring the
lowercase key and falling back to the capitalised one, and unescaping the
backslashes in destinationDir.
Tested against the real 44-entry catalogue, all three outcomes:
OptiPlex Micro 7020, pack present -> OK, win11_optiplexd13mlk7020_a09.zip
same model, pack removed -> FAIL, names the missing path
Surface Laptop 7 -> FAIL, no pack matches
Worth noting the check was failing SAFE - a WARN that reads like a tooling
glitch rather than a missing driver pack. It would have stayed invisible until a
bay imaged with no NIC.
