Microsoft started in earnest to carve out its own app store platform back in Windows 8 and it was a disaster. Barely anyone paid attention to it, which also left its Windows RT variant devoid of actually useful apps. It tried again with Windows 10 and its Universal Windows Platform (UWP) and had more success. But now it might have a new problem it needs to deal with and fast. With the influx of new apps on its Microsoft Store, the company now has to face the reality that there are some who are ready to game the system to trick users, even to the point of getting them to pay for something.
