Enable Developer Mode on Windows 10 PC and Mobile devices

Windows 10 is getting better and better, in every way, with each subsequent release adding new features and improvements. And the Settings app, one of my favorite spots to explore new things, is on a roll to phase out the classic Control Panel.

Now those days are gone forever when developers had to walk through a checklist to prepare Windows 10 PC and Mobile devices for Universal Windows Platform (UWP) app development, test and deployment.

With Windows 10 Anniversary Update, version 1607, we are greeted with a dedicated ‘developer-centric’ page in Settings, which is a kind of one stop shop for all developer features required to build UWP apps – an evolution of Windows Runtime (WinRT) apps.

What are Windows 10’s developer features?

Windows 10 now includes an array of configuration options that are categorized in two modes i.e. Sideload apps and Developer mode.

Sideload apps

As the name suggests, the Sideload apps allows app installs from unknown sources – like an app (.appx or .appxbundle package) downloaded from a website that you trust or internal to your company only, without going through the Windows Store however, you must provide and install a trusted certificate.

Developer mode

In the Developer mode, you can sideload apps, and also develop and debug apps using Visual Studio. Unlike Windows 8.1, there is no registration or developer license required. In addition, it lets you enable Windows Device Portal for remote diagnostics over USB and LANs, configure firewall rules for SSH services to install apps remotely, and install Windows Subsystem for Linux (Bash on Ubuntu on Windows) on a developer machine.

In addition, there’s a collection of Windows Explorer tweaks, and Remote Desktop and PowerShell settings that help you make a more developer friendly Windows environment.

Is Activating Windows 10’s Developer Mode safe?

This is tricky as enabling developer mode allows not only external apps to install without a trusted certificate, but also alters firewall rules for SSH services to allow remote installation of apps. So before jumping on the bandwagon, make sure what these apps are for.

I’m discouraging you but here’s the deal: If you are a regular computer user doing your day-to-day activities like playing games, web browsing, email or Office apps, you should avoid it. However, if you are a Windows developer and build UWP apps, it is must and you need to activate Developer Mode on both the developer machine, and on any devices, you’ll use to test your code.
