How to Stop Skype Use

[SimonInOz]

Hi,

 

We have an setup where students have W10 Edu, and despite all my efforts at stopping it, Skype still seems to be runnable.

 

I have tried locking down executables, applocker, registry setting changes, uninstalling it via powershell, group policy, Sophos UTM9 changes. It still runs.

 

Is there any way to prevent use of Skype (both Business and Store version) on a W10 domain pc?

 

I am totally frustrated with this one, and despite research cannot stop it from being used.

 

If anyone has a detailed map on how to stop this, it would be a great day for me. Happy to try anything really.

 

Thanks a lot.

 

This is what is running according to remote process explorer:

 

SkypeApp.exe,10256,276,1,095,29,8,C:\Program Files\WindowsApps\Microsoft.SkypeApp_14.44.40.0_x64__kzf8qxf38zg5c\SkypeApp.exe,7,221 K,0:00:8.796,282,308 K,3.40%,285 K,102,630,1 K,0 K,1,663,611,15 M,3 M,10,048,223 K,15/08/2019 9:02:29 AM,"C:\Program Files\WindowsApps\Microsoft.SkypeApp_14.44.40.0_x64__kzf8qxf38zg5c\SkypeApp.exe" -ServerName:App.AppXffn3yxqvgawq9fpmnhy90fr3y01d1t5b.mca

 

 

BTW, I have Sophos UTM9 which does a very poor native job of blocking skype, even though skype and SFB are included as blockable items. In fact, my students can run the windows skype easily, while SFB has issues running for staff and teachers...... yeah.

Have you got it working with Sophos Central?

If so, install the client then, go to the console page on Sophos Central and you can go to app control and block Skype out.

I have already selected Skype in application control, it is not stopping it.

Were you creating the AppLocker rule to block the Skype app as a "Packaged App Rule"?

This is what worked for us, can't do anything skypewise as long as sophos is on
