Windows Insider Preview Build 15042 allows users to install apps from anywhere or only from Microsoft Store. The feature can also tell the system to prefer apps from the Store but to accept apps from any outside applications. It mimics Apples Gatekeeper feature in most of its functionality. It has proven effective in helping to block malware like Adwind, the remote access trojan which has infected 1,500 companies in over 100 countries. The new Windows feature has yet to be confirmed for the general public.”]
