Well Windows 7 was my first WINDOWS os. I used to use linux as a kid because my mom found an obscure kid-centered distro for my first computer. It was slow as heck and had broken filter software. I don't miss it.
Windows 7 was a great OS. I used to drool over it when it was launched. Although XP was a great OS, I never had a liking towards it. It was Windows 7 that looked so modern and mean.
I believe after the bad decisions during the phase of Windows 8, Microsoft learned a lot and Windows 10 that they launched was an outstanding product. I use Windows 10 as my daily driver both at work as well as at home and it's great.
