Probably the same way as in any other version of Windows (although, given that Microsoft likes to make things more difficult with every release of Windows, I'm not guaranteeing it!):
Press PrtScn. Absolutely nothing will seem to happen but that actually dumps a screenshot into Windows' memory. Open any suitable program that will allow you to paste what's in memory. (If you want to actually print on paper, Word [or similar] will do. If you want to save the result as an image, Paint [or similar] is fine). Right-click within the document and select Paste (or go to Edit > Paste).
