Microsoft revealed earlier this month that Windows 10 is now installed on half a billion active devices around the world. Indeed, some variant of Microsoft's Windows operating system is likely what you'll find running on the average computer user's PC.

With this week's open forum, we're curious - what version of Windows are you running? Or, given that this is a tech-focused community, it's much more likely that you aren't running Windows. Perhaps it's your favorite distribution of Linux or something else entirely?
