Note: The following demonstration was done using virtual machines created in Virtual PC 2004, upgraded to Virtual PC 2007, and then upgraded to Windows 7 Virtual Machines. Instructions on how to create a virtual machine in Windows 7 and install a guest operating system follow. For this article, I will demonstrate Windows 7 Virtual Machines and Sun VirtualBox. I have used the top three ( VMware Player by VMware, Inc., Windows Virtual PC by Microsoft, and VirtualBox by Sun / Oracle). There are a few different Virtual Machines out there. That's when I started to use Virtual Machines ( Virtual PC 2004 & 2007). It lost functionally when one of the system DLL's it depended on got upgraded. So when I switched over to Windows XP, it ran fine until Service Pack 1. The last operating system it was released for was Windows 98. A few years back, I ran into this issue when one of my favorite search programs ( WebCompass) was discontinued.

I am often asked, 'How can I get an old program to run on Windows 7?'. In this article, I will show one of the uses for Virtual Machines in Windows 7.
