Preventing access to modern app

Ive been tasked with preventing the children from accessing instagram. I've got it listed in my windows hosts file and internet options/security/restricted site but the windows 10 app is still allowing access. Any suggestions other then deleting app which can just be reinstalled?

 

UWP App in Assigned Access and Windows Store for Business - what happens when an app update is available?

Junior Dev here trying to figure out how to deploy and manage a UWP app for multiple Assigned Access accounts (think restaurant kiosks) that I won't be able to physically access or have a user interact with
them for updates.

Question: If I had a UWP app on Windows Store for Business with a pending update, what happens when the app is currently running on an Assigned Access account?

• When does the app actually get updated? On the next reboot of the machine before the app is launched via Assigned Access?
• Is there a way to force the app to update and restart without a reboot of the machine?
• Is there any user interaction required for this to happen (like a UAC prompt)
• Does the AUMID change and if so does this break the assigned access?

Thanks for all you help!

 

Working around the Network Loopback Isolation of UWP Apps

I've been hitting a blockage trying to get my UWP App to receive data from a local UDP port in the following scenario:

• Windows 10 | Version 10.0.16299 Build 16299
  
• UWP target and minimum Version 10.0.16299
  
• Declared capabilities :
  
  • Internet (Client & Server)
    
  • Internet (Client)
    
• UdpClient listening on 127.0.0.1:1234
  
• Tested on two different systems in different networks with the same resulting behaviour
  

I am aware of the CheckNetIsolation tool and already tried the following steps multiple times:

• Ensuring that the App is registered while running with CheckNetIsolation loopbackexempt -s
  
• Clearing all exemptions with CheckNetIsolation loopbackexempt -c and manually adding the App with CheckNetIsolation loopbackexempt -a -n=*Package Family Name*
  
• Running the App while all restrictions are cleared with CheckNetIsolation loopbackexempt -c
  

I am running my App from Visual Studio, awaiting for UdpClient.ReceiveAsync() to return something in a while loop.

My code works fine when i use it from a .Net Framework 4.7.2 Console App, so i can exclude any errors interfering on that end.

The only thing that lets me receive data in my UWP App is running CheckNetIsolation loopbackexempt -is -n=*Package Family Name*. As soon as i stop it from running, my UDP client stops receiving aata.

Sadly, the solution i found and other tools that redirect communication so that they appear to be sent by another source are not possible due to different contraints.
