Windows

Police officers monitor CCTV screens in the control room at New Scotland Yard in London.

by Gaius PubliusIf you're like me and work on a Windows-based system, you get these popups from time to time offering to "upgrade" you to Windows 10, Microsoft's latest and greatest, for free. Normally these upgrades cost $100 or so. Me, I'm still on Windows 7, since like many I consider Windows 8 both half-baked for professional use and a data-suck for entertainment use.
