Solve : why some commands not support in my command prompt??

1.	Solve : why some commands not support in my command prompt??
Answer» i have a trouble with my command prompt.. for example, i try to enter command driverquery,systeminfo and another commands...but its doesn't WORK... why? It would help if we had a little info about your OPERATING system. If it's XP Home...you'll find those commands won't work. You can use them on XP Pro, however. Have you looked at this?
