Easy way to adjust the amount of CPU time a MS-DOS program gets from the system.


If you are like me, you still have a few MS-DOS programs that occassionally need to run for periods of time. Being able to adjust how much of the CPU these programs receive is very nice.

1. Right-click the program’s shortcut
2. Click Properties from the context menu
3. Click the Misc tab
4. Adjust the Idle Sensitivity

This tells windows how long to allow this program to be idle before taking away resources. Therefore, if you want a high amount of resources to be directed toward your app, set the sensitivity to low. If you want the program to use as little CPU as possible, set the sensitivity to high.

    THANKS!!!
    You save me!!!
    I need ocassionaly run FoxPro 2.5 (for DOS) in my XP machine
    and this program hog the CPU at 100% all the time.

    With this trick, the CPU usage is ~50%,
    still high, but it's fine for me.

    Thank you SO MUCH!!!
    you save me to downgrade to Win98.
