for windows xp go to start/help/customizing your computer--find keyboard and mouse in the left column--click that and follow it thru--make sure read it all cos u have to set the system to use alt languages--in ur case it will already have german so u will have to set it to use en as well then u get an icon on the task bar that lets u toggle between the 2 languages--any problems post back--for other os's 98,2000 and ME it will be similar can't remember about win95--so long since i used it but i am sure it is much the same
