Free recording program laptop?

I would like to film things on my laptop, but I can't find a free recording program.

If you know one, please write me.

Ocam - free, screen and game recording possible, good quality, unfortunately with advertising if you want to close the program.

Thanks

If you want it easy, press Windows + G and start recording. Afterwards, crop photos. Or you use OBS for which I would watch a little tutorial first

I would (and do) do it with OBS.

Then edit with Shotcut or DaVinci Resolve
