Download VirtualBox 4.1.2

Oracle has released an update to version 4.1 of VirtualBox. VirtualBox can be used to install other operating systems in a virtual environment on a computer. In this way it is possible to use different operating systems on the same hardware side by side and at the same time. VirtualBox is available for Windows XP and above, Mac OS X, Linux, and Solaris, and is capable of many guest operating systems to turn.

VirtualBox is available in two separate versions. The full version has additional functionality, such as support for USB ports and the remote display protocol, but is only free for private use and evaluation purposes. The extra functionality is closed source and is therefore not present in the open source version. It may, however, be used in commercial environments, provided you install it yourself on the PC. In version 4.1.2 the following changes and improvements have been made:
