If we want multiple OS on a single system say Windows XP and Vista. One can make dual boot in a system. But, the dual booting process will be a slow process. It take minutes together to switch from one operating system to another. In order to work faster without the option of dual booting, it is better to make use of a conceptual program called as Virtual PC.


The Virtual PC is a program, which allows running operating system within an operating system. The main operating system which allows running other one within it is called as the host operating system. The operating system which is running within the host operating system is termed as guest operating system.

One can run Windows XP within Windows Vista by setting up Virtual PC 2007 in Windows Vista. Here, Windows XP is termed as guest to Windows Vista, which acts as host operating system.
