如何知道 UWF 是启用还是禁用

Question

How do I know if the UWF is enabled or disabled? I'm making an application with C # so I need to know for that language.

Thank you

There are few things to keep in mind when considering whether UWF is enabled or disabled:

1. Protection is not enabled when UWF is enabled, you need to exlicitly turn it ON by making use of Protect method in UWF_Volume class.
2. A system reboot is required after enabling or disabling of UWF in order to apply the changes. UWF_Filter class provides methods for enable/disable and for performing reboot/shutdown of the system.

The C# code below demonstrates the use of CurrentEnabled property of UWF_Filter class:

public static bool IsEnabled()
    {
        try
        {
            //root\standardcimv2\embedded
            ManagementScope scope = new ManagementScope(@"root\standardcimv2\embedded");
            using (ManagementClass mc = new ManagementClass(scope.Path.Path, "UWF_Filter",
            null))
            {
                ManagementObjectCollection moc = mc.GetInstances();

                foreach (ManagementObject mo in moc)
                {
                    // Please make use of NextEnabled property in case you have enabled the UWF_Filter in the current session. 
                    //The value in CurrentEnabled is populated only when the UWF_Filter was enabled on system boot.
                    return (bool)mo.GetPropertyValue("CurrentEnabled");
                }
            }


        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
            throw;
        }
        return false;
    }
