During Build 2016, Microsoft unveiled a cool app converter that turns desktop applications into Universal Windows 10 apps. Essentially, the Desktop App Converter serves as a bridging tool between Win32 apps and Universal Windows Apps, in much the same way that Project Islandwood does for iOS apps. Run a Win32 app through the Converter, test it, plug in the additional UWP features and functions, and then push to the Windows Store. Here's how Microsoft describes the tool:
Desktop App Converter allows developers to bring their desktop apps to UWP. It converts a desktop Windows installer such as MSI or exe to an AppX package that can be deployed to a Windows 10 desktop. The software may collect information about you and your use of the software and send that to Microsoft.
Microsoft has rolled out a preview version of the tool and you can download it from this link right here. Give it a try and let us know your thoughts in the comments below.

Before you download the tool, note that you will need to be running Windows 10 Enterprise Edition Anniversary Update (Redstone) build 14316 or newer. Thanks Tony for the tip!
