How to prevent Windows 8.1 from automatically updating Modern apps

With Windows 8.1, Microsoft has introduced a lot of improvements over Windows 8. One such improvement is the automatic app update feature, which downloads the latest versions of all Metro apps and allows you to keep them always up-to-date. In Windows 8, you had to update your apps manually.

However, some users may prefer to approve app updates manually. There are several reasons which my friends cited for this. The most common reason was: "The new version of the app broke/removed my favorite feature". That makes sense, you certainly don't want an update to delete or break any existing functionality. So for such perceptive users, it's better to simply disable the automatic updating of Modern apps. Let's see how.
