Jump start with an evaluation virtual machine

Try out the Windows 10 development environment without spending the time it would normally take to set up and configure a device for development or test use. Run this VM on your current Mac or PC for a 60-day evaluation of the Universal Windows Platform tools and technologies to accelerate bringing your existing code to Windows.

We've provided a Windows 10 development environment in a number of different virtual machine implementations - matched to the latest release and ready to go.

Choose your virtual machine implementation of choice to begin developing with Windows 10.
