Which programs don't work? Make sure that you have WinXP SP1 installed as well as the compatibiliy updates from WindowsUpdate. Also, create an icon for the program(s) in question, then look at the properties for the icon; you should see a Compatibility tab; select Win98 or Win95 compatibility, to see if that helps. Furher, note that there are two different command shells, one is CMD.EXE and the other is COMMAND.COM; you may get better results with COMMAND.COM. Microsoft went to some effort to make WinXP backwards-compatible with Win98, so your "several" statement kinda surprises me. I started out with DOS, so when I moved to Windows, backwards compatibility was important for me. Nearly everything that I wanted to use worked, and most of the rest either had better replacements in Windows (especially if they don't make mouse use mandatory, like some brain-dead programmers do), or don't really apply to Windows. With Win2K and WinXP, some programs are blocked for security reasons; logging on as Administrator ("Owner", on some brands) will bypass this problem. There's also an Application Compatibility Toolkit that you can download which has fixes for a large number of specific programs, mostly games. The problem with Win98 is getting drivers for the newer hardware. If the hardware is relatively standard, this probably won't be much of a problem. Also, if the machine has 512M or more of memory, you may have trouble. Also, you may not be able to use all of the hard drive space. --Scott.
