What is a good free screen recorder for PC that will, not only, record the screen as well as the audio, but can also record the audio from a microphone?

I searched and searched for a good one, and the best (absolutely free) one I found was Lolio Game Recorder. No watermark, unlimited time, microphone recording, as well as system audio.

Note that this is a GAME Recording software, meaning that it will only record one program. If you are doing a tutorial video, or something of that nature, where you will need more than one program recorded, I recommend Screencast O Matic or Bandicam. Both have limited time recording and a watermark, but they are the best I have found in this category of screen recorders.

You can use a free online tool, Videograbber. I can use it to download videos, record screen, and convert videos.

Hey! Check thisscreen recorder It records audio from mic and system sound in 2 separate tracks or mixes them together. It's up to you. It has many other useful functions to like LIVE streaming options, fast export and upload to YouTube and Facebook and much more. I love it for its great performance and ease of use. Definitely wroth to try. And it has nice interface too. Have a look
