Where Windows Server Update Services keeps its logs

Windows Server Update Services logs to %ProgramFiles%\Update Services\LogFiles\ on Windows. 2 other Windows log locations are recorded below.

Paths are printed exactly as Windows Server Update Services 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.
