Go to ‘Settings’ from the Windows Start menu.
Select “Privacy and safety” then “ Windows safety “
In the following window, click on “Open Windows Security“
This will open the Windows security settings page. In this window, select ‘App & browser control’
Next, select ‘Reputation-based protection settings’.
Deselect the option ‘Check apps and files’.
