Microsoft's Windows Mixed Reality isn't just for playing VR games—it's a platform for using applications with both VR and AR environments. Until now, you could only run UWP apps from the Microsoft Store in Mixed Reality, but that is finally changing. The latest Windows 10 Insider Preview build includes support for running traditional Win32 desktop programs inside of Mixed Reality.

"In this update, we added the ability to launch Desktop (Win32) applications (such as Spotify, Paint.NET, and Visual Studio Code) in Windows Mixed Reality," Microsoft said in a blog post. "To use this feature, bring up Pins Panel, then go to all apps, where you will find a folder named “Classic Apps (Beta)”. In this folder, you will be able to select and launch any Desktop (Win32) applications."
