Windows unrecognized application message

The system might display a Windows Defender SmartScreen message about unrecognized applications at the start of the installation process. The Administrator can either choose to continue with the installation (by selecting Run anyway) or perform specific steps before installation to prevent the message from appearing.


  1. Click the Windows key to display the Start menu.
  2. Enter gpedit.msc, and select the result (which can be Group Policy Editor or gpedit.msc).
  3. Navigate to Computer Configuration > Administrative Templates > Windows Components > File Explorer.
  4. Double-click the policy Configure Windows Defender SmartScreen and set it to Disable.
  5. Click OK to save the change.
