How to enable Windows 10 to sideload apps

On Windows 10, Microsoft continues to push its new modern app platform, which the company wants you to get primarily from the Windows Store. However, similar to other platforms like Android, you're also allowed to sideload apps outside the Store.

If you're unfamiliar with the term "sideload", in Windows 10 it means the process of installing apps on your computer that hasn't gone through the certification process to appear in the Store and to run on a Windows device.

The operating system by default blocks you from sideloading apps. The main reason is to protect you and your computer, as getting certified apps from the Store ensures that you're getting a good app that won't harm your device and it'll do what the developer says it will do.

However, there is number of good reasons to install apps outside the Store. Perhaps you're a developer, or you have a friend who is a developer and wants you to test an app before submitting it to the Store. It could also happen that you come across an app that leaked onto the web, and you want to try, or the fact that there a lot of apps available outside of the Windows Store.

In this Windows 10 guide, we'll walk you through the steps to allow the operating system to sideload Universal Windows Platform (UWP) apps on your computer.
