Can't let go of Windows 98 for compatibility reasons? Microsoft's Virtual PC can now be downloaded free. So what does it do?
To add a virtual machine with the operating system of your choice, you need the original Windows or DOS installation disks. If you own any Windows games that won't run in XP or Vista, this is more convenient than dual booting. DOSBox, Compatibility Mode and a few fan-made patches are enough to get the Wing Commander games running on a modern computer, however, and may be easier for novice users to figure out.
