Record screen and audio
ffmpeg -list_devices true -f dshow -i dummy
You will get information on your micro e.g.:

Record screen and convert into gif
Here a small example of how to record your screen, resize the video and create from it a gif.
ffmpeg -f gdigrab -framerate 24 -i desktop screen.mp4
ffmpeg -i screen.mp4 -vcodec libx264 -vbr 3 -vf "scale=640:-2" -preset fast -crf 23 screen640.mp4
ffmpeg -y -i screen640.mp4 -vf palettegen palette.png
ffmpeg -y -i screen640.mp4 -i palette.png -filter_complex paletteuse -r 20 screen640.gif

Add variable to system variable PATH (Windows)
The first version of this batch file was pretty simple:
- ask user which path to add
- add it
The problem is that I realized that it was creating duplicates, and rapidly your system variable PATH is full. I then created a version which would delete duplicated lines.
Version: v04

Right click delete fast a folder (do not have to wait to continue to work)
Copy those lines in a .txt file and save it as a .reg. Run it to add this Registry key. This key will allow you to have a new menu when you right click on a folder to delete it fast. The advantage is that is faster that the normal deleting method from windows and it will keep your explorer free to be used (useful for huge folder).
