How to: Modify Permissions in a Permission Set

Use the .NET Framework Configuration tool (Mscorcfg.msc) to modify a permission in a permission set.

Important noteImportant

Mscorcfg.msc has been removed from the .NET Framework version 4 and later versions. This documentation applies only to earlier versions of the .NET Framework. For more information about security changes in the .NET Framework 4, see Security Changes in the .NET Framework 4.


The .NET Framework includes several built-in permission sets. The only built-in permission set that can be changed is the Everything permission set.

To modify a permission in a permission set using Mscorcfg.msc

  1. Run the .NET Framework Configuration tool (Mscorcfg.msc).

    1. In Control Panel, open Administrative Tools.

    2. Double-click Microsoft .NET Framework <version> Configuration.

    Alternatively, you can run the tool from a command prompt:

    • In the .NET Framework versions 1.0 and 1.1, type the following at the command prompt: %Systemroot%\Microsoft.NET\Framework\versionNumber\Mscorcfg.msc

    • In the .NET Framework 2.0, start the Visual Studio and Windows SDK Command Prompts and type mscorcfg.msc.

  2. Expand the Runtime Security Policy node.

  3. Expand the node for the policy level you want to change the permission for.

  4. Expand the Permission Sets node.

  5. Right-click the permission set whose permission you want to modify and choose Change Permissions.

  6. Select a permission from the Assigned Permissions list and click Properties. The Permission Settings dialog box appears, which contains information about the selected permission. Change the information for that permission and click OK.

  7. Click Finish.
