Windows 10: How to block all applications / programs except few

Hi,


When it comes to Web browsing there is a great option in the Content restrictions section to only allow specific websites.


But how about only allowing specific applications/programs and all other applications/programs should be blocked by default?


Is this possible to setup?


Of course I can use the "Always block" but this means that I constantly need to block all newly installed applications on the PC.


Thank you.

:)

 

blocked applications

Hi Eileen,

Windows Defender or another antivirus software will sometimes block a certain app or file from running or being installed. With this, you can check the
quarantine section of the antivirus program you are using to see which program is being blocked. To better assist you, we need the answers to the following questions:

• What is the exact error message did you receive after launching or running the app?
• Which antivirus program are you using?

In the meantime, we suggest disabling the Windows Defender SmartScreen and see if the app will run. To do this, simply follow the steps below:

• Type Windows Defender on the search box and click on the first option.
• On the left side of the window, click on the Window icon (App & browser control).
• On the SmartScreen for Windows
  Store apps column, select Off.

We are looking forward to your response.

 

FIREWALL IS BLOCKING CERTAIN PROGRAMS

Hi Joseph,

Thank you for posting on Microsoft Communities.

I will be glad to help you with the issue you have with the computer. I understand the frustration when things don't work the way it should.

One of the most common problems when using a network firewall is that it sometimes blocks network traffic that you want to allow.

Please follow the below step to troubleshoot with the issue:

• Open the “Control Panel“.
• Select “System and Security.
• In the Windows Firewall section, select “Allow a program through Windows Firewall“.
• Unchecking the box to the left of the application name disallows it from accessing network resources, while checking it allows access.
• If the program you wish to block or unblock is not listed, you can click the “Allow another program…” button to add it. Choose the application in the list and select “Add“. If the program is not in this list, use the “Browse…”
  button to select the program file manually.

Hope this information is helpful. Please post in case you have any further issues, I will be glad to help you further.

Thank you.

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
