Enabling And Disabling Screen Capture In Windows 10

Here are the steps: 

Step 1: Open a blank app and add a Button and a TextBlock either from the toolbox or by copying the following XAML code into your grid.

<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
<Button x:Name="captureButton" Content="Enable Capture" Click="captureButton_Click" />
<TextBlock Name="status" Margin="0,10,0,0"></TextBlock>
</StackPanel>

 

Step 2:

Copy and paste the following code to the cs page which will be called on button click event and will control the ScreenCapture and will show the status also:

private void captureButton_Click(object sender, RoutedEventArgs e)
{
    if (captureButton.Content.ToString() == "Enable Capture")
    {
        captureButton.Content = "Disable Capture";
        status.Text = "Screen Capturing is enabled";
        Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().IsScreenCaptureEnabled = true;
    }
    else
    {
        captureButton.Content = "Enable Capture";
        status.Text = "Screen Capturing is disabled";
        Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().IsScreenCaptureEnabled = false;
    }
}

When the ScreenCapture is disabled you will only get a black screen while trying to capture the same using any tool. 

Step 3: Run your application and test yourself.
