  • Windows 7 32-bit EMS, XMS

    Windows 7 32-bit command prompt has no EMS, and minimal XMS.

    You could fix this on XP by changing system32\_default.pif settings. But
    with Windows 7 this file is protected and can't be changed.

    Google found many people with the same problem, but no solution.

    So I booted into safe mode to look around. The _default.pif owner was
    trusted installer. I tried giving administrator full control, but could
    not I kept playing with full control and ownership and eventually got
    the owner changed to administrator, with full control. Then I was able
    to change the memory settings for _default.pif.

    It was late and I don't remember all the window clicky steps, but in
    safe mode, it is possible to change the owner. Someone should document
    the steps, but I don't remember what they were. :-/

    Oops, _default.pif is in \windows not system32.

    In Win7, there should be a prompt for administrator priviledge when a file property is about to be changed. Simply pressing the "Continue" button n
    that prompt would allow the changes to be applied.

    If the UAC feature is disabled, the access elevation feature would also be disabled. So, no administrator priviledge prompt will be shown, and the file will not be changeable. Unless it's done by explicitly using other user
    account which is a member of the Administrator group.

    I don't see that prompt.


    If the UAC feature is disabled,

    Mine is set to never notify. Maybe that means disabled.

    My user account is in the administrators group. I don't know if safe
    mode was required, but somehow I changed the owner of _default.pif while
    using my account. Windows security is a mystery to me.
