and what the hell would you be pasting into word or paint for??
There are much better ways to save a screenshot - use the built in snipping tool in windows or use a 3rd party product, I use faststone capture daily
What exactly do you need the screenshots for? Are you trying to create documentation on how to do something, wanting to document a bug or issue?
So more details of what your project is about, and I am sure we can point you to a more efficient method than print screen and pasting into paint
