VirtualBox is a virtualization software is the best and the lightest that you can use to test an operating system either windows or linux under the existing operating system . the point here you can install windows like windows xp , windows 7 , windows 8 , and linux without having to install by removing the windows system which already exists on your computer / laptop . This software is very useful for you who love to keep changing the operating system on your computer or laptop .
For you who want to install windows / os latest , before you install it , you better first test as to what you want to install windows so that later you do not commute to install windows on your computer / laptop if you install windows that are less suitable for you . It is a virtual tool windows is not so perfect as when installing directly on the PC or computer, but at least we can see / know almost 90 % of the Windows OS that we test in this VirtualBox .
This virtualization software including virtual software that is very lightweight and easy to use , because it has a simple look , so it is easily understood by common people . Then this software is open source software , so you do not need any license to activate this software .
To be able to use virtualbox optimally you should always update to the newest version of the software , as this will affect the process of testing the windows that we do in VirtualBox . Well this time I got this software with the newest update VirtualBox 4.3.4.91017 Final .
