Virtual P.C.is an emulation solution that lets us to run more than one operating systems on one computer. We install Virtual P.C on to the host operating system (Windows XP, Windows 2000, Windows NT or Windows ME). We can add guest operating systems to the computer and run these operating systems in user in configurable windows or as a full desktop from the host computer using the Virtual P.C.We can use modern features & older applications and make older applications more stable in addition to providing backup configurations of our OSes.The ability to copy and backup Virtual P.C files also mean that we can easily duplicate our work. Once we?ve developed a configuration tuned exactly as we want it, we can apply to it as many PCs as we have licenses for that operating system. Running multiple operating systems on multiple computers would be expensive and cumbersome. The only better way is VIRTUAL P.C.VIRTUAL PC has helped in running operating systems simultaneously and thus increasing the profit of many multi national companies. It is of no doubt that Connectix will surely come out with an improved version of VIRTUAL PC in the near future.
