Capture Screen with ffmpeg / screencast

On Windows you can record your screen to an .mp4 file using ffmpeg:

  • Download ffmpeg for Windows from
  • Run e.g. with following command: ffmpeg -f gdigrab -framerate 30 -show_region 1 -i desktop out.mp4

(the capture devices




did not work for me on my Windows 10 machine, they were not even listed in the available video devices.)

For details see ffmpeg's

On Windows 10, you can also try to use Windows' Screen Recording to record a window. Just press Win+G and check Yes, this is a game. Afterwards you get a Record button. Your recordings will be saved to %HOMEPATH%\Videos\Captures

Start an application with the debugger attached

You can automatically attach the Visual Studio Just-In-Time debugger when a process is started on Windows. The steps are simple:

  • Open the Registry Editor
  • navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
  • Select the application you want to debug:
    • Either it already exists as subkey, then use that one
    • Or, you have to create a new key in Image File Execution Options with the name of the application (e.g. chrome.exe)
  • Create a new string value with name debugger and name vsjitdebugger.exe
