Return codes for WINUPTP


For Lenovo ThinkPad computers the standard utility to perform a BIOS update is WINUPTP.exe (or WINUPTP64.exe). This utility can be called with a -s parameter to stage a BIOS update silently that will complete when the system is restarted - presumably by your task sequence.


To date, the possible return codes from this utility were not readily available. This post is meant to correct that. Below is a table of possible return codes from WINUPTP.exe:
