To cast to Roku from a PC in Windows 11, make sure that your PC supports Miracast technology and that you have enabled screen mirroring on your Roku device.

Both Windows and Mac have free software to capture video of your screen activity. You just have to know where to look.

Now in Windows 11, the Snipping Tool can record video of your screen, in addition to taking standard screenshots.

Microsoft is finally bringing a native screen recording tool to Windows. The Snipping Tool is being updated in Windows 11 to support screen recording.
