Two days ago, I finally gave up Windows 7. I don't dislike Windows 10, but there's just always been something special about Windows 7. It was svelte. It actually ran faster and took up less hard drive space than its predecessor, the much-maligned Windows Vista. It looked great. We Windows users could finally hold our heads a little higher around Mac users. And, well, I didn't know how well Windows 10 would work on that old Windows 7 laptop, or how much time it would take to make the transition.

But Microsoft forced my hand. Tuesday is the last day that Microsoft will support Windows 7. "If you continue to use Windows 7 after support has ended, your PC will still work, but it will become more vulnerable to security risks and viruses," the company says. In other words, if you don't want to leave your computer open to ransomware and other threats, you better upgrade.
