Microsoft Edge WebView2 Runtime

Where Microsoft Edge WebView2 Runtime keeps its logs

Microsoft Edge WebView2 Runtime logs to %ALLUSERSPROFILE%\Microsoft\EdgeUpdate\Log\MicrosoftEdgeUpdate.log on Windows. 1 other Windows log location is recorded below.

Paths are printed exactly as Microsoft Edge WebView2 Runtime 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.
