When the Admin Approval Mode is enabled, the local administrator account functions like a standard user account, but it has the ability to elevate privileges without logging on by using a different account. In this mode, any operation that requires elevation of privilege displays a prompt that allows the administrator to permit or deny the elevation of privilege. If Admin Approval Mode is not enabled, the built-in Administrator account runs all applications by default with full administrative privileges. By default, Admin Approval Mode is set to disabled.docs.microsoft.com
