A new PC with different username cause two issues for WINE when copying old PC user files to a new PC.
Update WINE shortcuts
If the Linux username changed, you have to update the “exec” lines of the .desktop files that reside in
~/.local/share/applications/wine/Programs/ (or create softlinks).
Update drive shortcuts
Sometimes the drive links in
~/.wine/dosdevices differ after copying–as above, update your shortcuts/softlinks as necessary.
