How to block or allow certain programs in Windows 10

Microsoft’s Windows allows the System Administrator to create multiple user profiles. Still, then if you do want to limit specific applications to the users or block the application, you can make them stay away from those applications. In this post, I will guide you on how to block specific programs on Windows 10.

How to block or allow certain programs in Windows 10

The job of blocking access to specific programs on Windows 10 could be accomplished in a couple of ways. Here’s the list of methods that we will be following in the guide mentioned below:

  1. Group Policy Editor
  2. Windows Registry Editor

Windows 10 Home users can use the Group Policy Method, but they will have to install it. Learn how you can enable Local Group Policy Editor in your version.

1] Group Policy

For users running on Windows 10 Enterprise or Windows 10 Pro editions, the task of blocking access to specific programs could be a lot easier as they could use the Local Group Policy Editor to do so. The Group Policy Editor comes with a slight advantage over the next method of using the Windows Registry, as they won’t need to apply the same settings for different users, they could just change it for all users in a click.

  • Open Registry Editor by typing gpedit.msc in the Run Prompt (Win + R) followed by pressing the Enter key.
  • On the left of the screen, you’ll find two folders, namely the Computer Configuration and User Configuration. Under the User Configuration, navigate and expand Administrative Templates.
  • Under Administrative Templates, navigate, expand and select System. Now, next to the navigation pane, you’ll find a few folders and files listed.
  • From it, Open the policy Don’t run specified Windows applications by making a double click on it. In the menu that pops-up, set the policy to Enabled and then click on the Show button under Options.
  • Now list all the programs that you want the user not to be able to access, in the format such as ‘itunes.exe’,’chrome.exe’, and click on OK.

2] Windows Registry

How to Block Certain Programs on Windows 10 - via Windows  Registry

We could also use the Registry to block certain applications for users, but we do recommend only trying this method if you know what you are getting into. Also, make sure to make a System Restore before you start making any changes in the Registry.

  • Open Registry Editor by typing Regedit in the Run Prompt (Win + R) followed by pressing the Enter key.
  • On the left of the screen, you’ll find multiple folders. Navigate to
  • Now we need to create a new DWORD under the Explorer. To do so, right-click on the space right next to the navigation pane. From the drop-down, select New DWORD (32-bit) Value and name it as RestrictRun.
  • Double click the newly created RestrictRun to open the properties for it. Now change the Value Data from 0 to and click OK.
  • Now make a single right-click on the Explorer Key and move ahead by choosing New Key. Name it as RestrictRun and click OK.
  • Under the newly created RestrictRun key, right-click in the space and create a new string file, name it as “1″. Double-tap and open it and in the Value Data space, enter the name of the file you want to restrict, for example, ‘Notepad.exe’.
  • Carry on Step 6 for as many applications you would like to block, by naming the string files as 1, then 2, then 3 and so on.

Preventive Methods to block app installation in the future

You can use the SmartScreen feature and Microsoft Family settings to block other users from installing a program. That way, you can control which applications to install and which one should be allowed for everyone.

1] Enable SmartScreen via Windows Settings

  1. In the Seach Box, type in App and Browser Control and open the main listed result.
  2. Under Reputation-based protection, navigate and select the menu for Reputation Based Protection Settings.
  3. Make sure that the checkboxes for all the four menu’s (Check Apps and Files, Smartscreen for Microsoft Edge, Potentially Unwanted App Blocking, and Smartscreen for Microsoft Store) and are turned on.

2] Enable SmartScreen via Group Policy Editor

Computer Configuration > Administrative Templates > Windows Components > File Explorer
  •  Double click on Configure Windows Defender SmartScreen policy to open it

3] Microsoft Family method

  • Head over to and login with your Parent’s Microsoft account.
  • Under it, Find your Child’s Name, say, for example, “Raj” and select Content Restrictions.
  • Under the Apps, Games and Media Menu, Switch the toggle for Block inappropriate apps, games & media from Off to On.
