VirtualBox is an open source virtualization tool that lets you run Linux in a Windows environment and vice versa. VirtualBox creates a virtual partition on your hard disk, where the virtualized OS is installed and which you can access as if you were actually running it. The partition can be fixed or dynamic in size. You can download VirtualBox for Windows free from this page.
VirtualBox for Windows has many uses. You can install another operating system on a separate partition or drive so you can easily switch between them. This is ideal for testing software or trying new operating systems without affecting your main installation. You can also use VirtualBox to run older applications that are not compatible with your current operating system.
