Windows 10: Enable or Disable Microsoft Store Apps Open Files in Desktop App

How to: Enable or Disable Microsoft Store Apps Open Files in Desktop App

How to Enable or Disable Microsoft Store Apps Open Files in Default Desktop App in Windows 10


If you like, you can configure a group policy setting that lets you control whether Microsoft Store apps can open files using the default desktop app for a file type. Because desktop apps run at a higher integrity level than Microsoft Store apps, there is a risk that a Microsoft Store app might compromise the system by opening a file in the default desktop app for a file type.

If you enable this policy setting, Microsoft Store apps cannot open files in the default desktop app for a file type; they can open files only in other Microsoft Store apps.

If you disable or do not configure this policy setting, Microsoft Store apps can open files in the default desktop app for a file type.

This tutorial will show you how to enable or disable Microsoft Store apps from being able to open files in the default desktop app for a file type for all users in Windows 8 and Windows 10.

Apple Claims Steam Link App Violates App Store Guidelines

Here's what Valve is contending with:
App Store Review Guidelines - Apple Developer

The ones that stand out that may have caught Steam Link:

So yeah, there's a lot of reasons why Steam Link would get rejected.

App submissions and approvals is a thing between developer and Apple. Valve intentionally let this information leak probably because Apple's restrictive guidlines will never allow Steam Link to be on the store. Valve is hoping the Steam user base makes a lot of noise so Apple grants Valve and exemption. I doubt it will work. Apple loves control and Steam Link is a portal into the Linux/Windows ecosystem. Even if Steam Link were exclusive to Mac OS, Apple would likely demand Valve use Mac OS's remote desktop features rather than Steam Link.

I'd be shocked if Apple allows it.

 

Microsoft is purging a lot of low quality apps from the Windows Store

"Microsoft is sending emails to some Windows Store developers informing them that their apps have been removed from the Store for violating its quality standards."

"Neowin reports that app developers have been receiving these emails over the past couple of days:

In its latest review of the Store, Microsoft is evaluating if the published apps are good enough to be listed in the Windows Store. This includes publicly available apps as well as private beta apps. Additionally, Microsoft is also asking developers to delete any promotional campaigns for their apps to prevent advertising charges. Similarly, app name reservations are also being nullified; which means that if your app is unpublished, there's no guarantee that you'll be able to republish it under the same name.

Officially, the policies for the Microsoft Store says that apps must have "distinct and informative metadata" and "provide a valuable and quality user experience". There are also some specific standards that must be in the apps, including having a name that is not similar to another app or device, along with offering a description that is accurate about its features and functions.

There have certainly been many Windows Store users who have complained over the years about the large number of apps published that are clones of other apps or ones that are simply poorly made. Hopefully, this new move by Microsoft will help to curb these issues, at least for now."

Microsoft to remove low quality apps from Windows Store

 

Mail app will not open on 10041.


Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

 

Microsoft is purging a lot of low quality apps from the Windows Store

About time.
I would greatly appreciate, if MS had separated smartphone/tablet apps from Desktop/Laptop apps (at least created dedicated categories for such apps).
The actual delivery mechanism of Windows Store is very good, and very usable (much better than Ubuntu Software Center), but the content is either not there, or meant to be used on a touch-enabled device.
