Apparently in Windows 7 Microsoft has _default.pif protected and won't allow it to be changed even it file ownership is granted to Administrators.

Under XP, it was possible to change the settings in _default.pif. On Windows 7 32-bit, is there a way to alter the default settings? I would rather change the Expanded memory and Extended memory values to default to "Auto" instead of None and 0. Otherwise, I will have to set the properties for each DOS program.
