I've been running Windows 7 on my computer for ages now. When Microsoft offered the free upgrade program I took advantage of it and absolutely hated Windows 10. There were plenty of issues with hardware and drivers immediately after launched so I rolled back to 7. Apparently because I once had 10 installed, I can still reinstall it. Now that it is a few years later, how good is 10? Is there anything that I am really missing out on by not upgrading? Will I see any better overall performance in day-to-day tasks, heavy workloads, or games? Or is it just a matter of new bells and whistles?
