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.
  1. <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">         
  2. <Button x:Name="captureButton" Content="Enable Capture" Click="captureButton_Click" />  
  3. <TextBlock Name="status" Margin="0,10,0,0"></TextBlock>  
  4. </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:

  1. private void captureButton_Click(object sender, RoutedEventArgs e)  
  2. {  
  3.     if (captureButton.Content.ToString() == "Enable Capture")  
  4.     {  
  5.         captureButton.Content = "Disable Capture";  
  6.         status.Text = "Screen Capturing is enabled";  
  7.         Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().IsScreenCaptureEnabled = true;  
  8.     }  
  9.     else  
  10.     {  
  11.         captureButton.Content = "Enable Capture";  
  12.         status.Text = "Screen Capturing is disabled";  
  13.         Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().IsScreenCaptureEnabled = false;  
  14.     }  
  15. }  

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.
