If you’re reading these words on a Windows PC, congratulations! You are not alone. Although other OSes have grabbed some market in recent years, Microsoft still owns the place, with 90 percent of PCs running some version of Windows.

Support for Windows XP is officially dead, and it’s finally time for those who were scared off by the disaster that was Windows Vista to upgrade. If you’re lucky, you can still snag a machine running the popular and well-regarded Windows 7. Microsoft would like it if you upgraded to Windows 8, though, so much so that it keeps updating Windows 8 to be more like the last one. You know, the one people liked.

But that’s just the recent news. Chances are you’ve been using Windows since long before anyone was wondering what “XP” was supposed to mean. Windows has been through a lot of forms over the years, all of them good and bad and weird in their own ways.
