This is a super useful tool, but most often I paste into mspaint and mark up from there.
Printscreen copies the screen to the clipboard, and is then pasteable. (I just tried the Twitter example and it worked.)
Select a window and Alt + Print Screen captures just that window.
It's not capturing the screen that people are going to miss. It's making changes to those that people are going to miss. Paint just works, and is really quick.
But if you do have One Note, this is much easier than using Paint.
Except now they have a "but it's about keeping the users safe" pretext, so they don't catch as much hate for it.
They're not catching much flack for it, because they're no longer feared as they were in the late 1990s, due to the devaluation of the desktop PC. It's no longer regarded as the center of the tech universe, nor is it regarded as the future economic gateway through which everything will flow (as was commonly believed 20 years ago). Back then, Microsoft stood practically alone as the gorilla of the technology industry, today that's not even remotely the case.
