You might have read the news that it’s no longer possible to use the built-in Group Policy SETTING to prevent access to the Windows Store starting in Windows 10 / 1511 with some updates. I don’t make the news, I just report it.
The official article at Microsoft is ”Can’t disable Windows Store in Windows 10 Pro through Group Policy: https://support.microsoft.com/en-us/kb/3135657“. Except, good news.. turns out there IS a way to prevent Windows Store from running with Windows 10 Pro.

UPDATE: Found another technique which works with “Software Restriction Policies”, which is a little less intense than using, say, AppLocker to do it. Personally, I prefer the method in MY video, but this alternate method using SRP should work a-ok for most people as well. Link to another blog / video.
