However, sometimes VirtualBox performance sucks. It is not like running apps on the desktop, but apps do run quite quickly in virtual machines. Running software in an operating system running on a virtual machine (emulator/simulator) on top of an operating system like Windows can be quite good. You can even download Windows for free and run it in VirtualBox. Linux distros are free and work great in virtual machines. VirtualBox is great for testing software because it runs in the virtual machine and does not affect, or infect in the case of malware, the rest of the PC.ĭownloading and installing VirtualBox is easy and the software is free. It is a sort of PC simulator or emulator and the guest OS that is installed, such as Windows, Linux and so on, runs in a window on the desktop like regular software apps. When an operating system is installed into VirtualBox it runs as a virtual machine. VirtualBox is a great way to run other operating systems on your PC without having to partition the disk, fiddle around with boot managers, and other technical matters, all of which can cause problems if not carried out properly.
