Windows 8.1 is a free upgrade to Windows 8. It’s what the original Windows 8 should have been, with important improvements for both desktop and tablet users. So why are more people using Windows 8 than Windows 8.1?
It’s hard not to see this as a failure for Microsoft. Windows 8.1 is the first “new version” of Windows they’ve given out for free to existing users and most Windows 8 users aren’t biting.
