You could always try to torrent a program haha

I use Camtasia Studio myself, it works really nice, plus it has a built-in editor!

I use Fraps and it's pretty good. If you're looking for a FREE recorder, that may be difficult. They all have their downsides. Bandicam is good, but it has branding and watermark, and a max of 10 minutes of recording. hypercam has horrible watermark, Fraps only allows 10 seconds of recording, but no watermark... It just depends on what you're trying to do. I would really recommend buying Fraps, although it is a bit pricey ($39.99). I bought that and I don't regret it.

i agree with Namechange

But depends on your preference really i prefer Fraps tbh i love the amazing quality it provides and when used with sony vegas for editing the file size reduces a lot with out any quality loss.

OBS or shadowplay
