Ready to Bitch-Slap Cortana

I switched to Windows 10. Not that I was particularly unhappy with Windows 8 or 7, which I had on my existing computers. But since I still have an XP computer that is now a door stop since it is no longer supported, I figured I'd upgrade while it was free. What is with their Internet Explorer replacement?

Twice now (at least), it has simply killed every open tab I had. Some stuff was for blogging. Some was for writing. The latter I tend to bookmark so they aren't gone. But the former? Well, how much time am I supposed to devote to finding them again?

Ah, I can feel my Internet experience enhancing as we speak.
