Yes, with an emulator. Virtual PC is the best choice here. Be warned though, this process of emulating an operating system inside another operating system is a massive resource drain. Everything you do in the Window's environment will suffer greatly and some things are simply impossible or at least impractical. If you need to run a lot of Windows' software, you're going to want a Windows machine, in my opinion. James Edward Gray II
