PC gamers forced to upgrade as Valve ends Windows 7 support for Steam

If you've got an old gaming PC that you've been using to do some casual to moderate gaming on, I hate to break it to you, but Valve needs you to change. 

Specifically, Valve needs you to drop Windows 7 and Windows 8 and upgrade to at least Windows 10 if you want to keep using Steam as your one-stop gaming shop after this year.
