I had a look into the sources; I can't find a line of code where winGRASS changes %HOME% at the moment; but it obvious uses %USERPROFILE% as %HOME%. and %USERPROFILE% points to in (at least newer) windows versions to e.g. echo %USERPROFILE% C:\Users\hkmyr C:\Users\\rsb etc. in a vanilla windows console, %HOME% isn't defined: echo %HOME% %HOME% within a winGRASS session echo %HOME% C:\Users\hkmyr it points to the folder defined under %USERPROFILE% add following line SET HOME=%USERPROFILE%\Documents below https://trac.osgeo.org/grass/browser/grass/trunk/mswindows/env.bat#L23 has following effect within a winGRASS session: Cleaning up temporary files...
