I do the following;

takeown /A /F C:\Windows

icacls C:\Windows /grant Users:F /inheritance:e

takeown /A /F %systemroot%\win.ini

takeown /A /F %systemroot%\_default.pif

icacls %systemroot%\win.ini /grant Users:F

icacls %systemroot%\_default.pif /grant Users:F


But my MSI install package still does not overwrite _default.pif.
However I can use "copy" command to overwrite _default.pif.

How do I get MSI install package to overwrite the file, what do I need
to do? I could perhaps install _default.pif in some other directory
and issue a "copy" command but that would be a roundabout and indirect
way of doing it.
