Where Lenovo System Update keeps its logs

Lenovo System Update logs to %PROGRAMDATA%\Lenovo\SystemUpdate\logs\ on Windows.

Paths are printed exactly as Lenovo System Update writes them. Environment variables like %LOCALAPPDATA% and $XDG_STATE_HOME are never expanded, so a path can be pasted straight into a shell. Where a path differs between installer types or shipping flavours, each one is racked as its own card below - why that happens.
