Thanks, but I'm not inclined to spend $49.95 for Snagit.
If I remember, it had the option to check for updates automatically during the installation, which I didn't choose...if memory serves. That is something that I do with most programs, even though it might be more convenient to let it do so.
I am using Printkey2000 for both Win 7 and Win 8. It's a portable app (no need to install). Try it. I attached it here.
Tip: if you want to capture a portion of your screen, use the RECTANGLE mode and then save it as jpeg or print it right away.
My setup is to notify me for update.
Open Picpick > File > Program options > About > under Preference > Check for program updates > OK.
Not sure, because with that enabled, it still keeps calling home.
