I use my computers built in snipping tool to capture screenshots. I can then use the built in paint tool to write or highlight something on the image. No need for other programs
If you enjoy wasting time, then paint is great. If you do ANY sort of screenshots, then something like SnagIt is the best little program. As part of my daily process, I take screenshots of the entire day w/ my notes over them and no way I would attempt to do this in paint. SnagIt is one of the best programs I use daily in my trading.

I notice you guys focus on a lot of charts. My screen is pretty boring, its 1 chart and mainly the NYSE openbooks and options books.
