If you are often finding yourself opening Notepad, pasting content, and copying them again just for the sake to remove all the formatting, then PureText is a right tool for you. It does all that but in a single step.
With PureText installed, just copy the content of your choice, then upon pasting press Windows+V (instead the usual Ctrl + V) — and you can alter this shortcut to your liking as well. It’s also very light at 13 Kb.
