How do you capture a screenshot on a PC?

Press the PRTSCN key (or hold the control key and tap prtscn, depending on the system).

It saves a copy of the screen at that instant in the system clipboard.

Then open Paint or some other image/photo editor and use the edt/paste option to transfer the captured image to that.

And then save the image as a jpg or png etc., whatever format you want.

You can crop it before saving if you only want part of the screen.
