Well, when Windows 7 was released there was one very nice feature which was much talked about by the geeks and that was the Windows XP Mode. Well, Windows XP Mode is part of a seperate installation by which you can run Windows XP on your Windows 7.
But the catch was that in order to use Windows XP mode Microsoft made it mandatory that you must be running Windows 7 Professional or Windows 7 Ultimate - also your PC must have virtualization support by the hardware.
These mandatory requirements was a downer and many users weren't able to truly enjoy Windows XP Mode. But here some very good news - enter the VMLite which is a very nice alterative to Microsoft's Windows XP Mode.
VMLite XP Mode does offer very similar features like the Microsoft XP Mode but lo it doesn't need you to have Windows 7 Professional or Windows 7 Ultimate - so even Windows 7 Starter edition will work fine and also it doesn't require hardware virtualization.
VMLite allows you to easily run Windows XP from your desktop running on a different host operating system - not just Windows 7. You can download VMLite here.
