Virtual machines are more useful than just for fun and games, and they’ve helped me a huge deal in work-related areas of my life. Using a virtual machine offers a great sandbox if you’re ever dealing with sketchy software that may be riddled with things that you’re way too nervous to allow on your main disk.
We’ve lavished attention on VirtualBox here at MakeUseOf, and for good reason. However, VirtualBox isn’t your only option for creating and using free virtual machines. VMware Player, VMware’s free product, is every bit as good as VirtualBox for many users. You may even prefer it to VirtualBox. VMware Player runs on Windows and Linux.
