There’s been a lot of coverage in the Windows trade press around Windows 10’s tenth birthday. It made its debut on July 29, 2015. As I’m pondering Windows 10 turns 10 — and its upcoming EOS on October 14 — I asked myself “How does a 10-year lifespan compare to other Windows versions?” Obligingly enough, Copilot provided me with a text-based histogram that lays things out as far back as Windows 1.x versions. It serves as the lead-in graphic for this post.

Pondering Window 10 Turns 10: Lifespans Compared

Here’s what I see when I look at that chart:

• Only two versions have had longer runs than Windows 10 — namely, Windows XP (13 years) and Windows 7 (11 years). Both are arguably the Windows champs as far as versions go, and I used the heck out of them during their heydays.
• I’d have to say that a life span of under 7 years pretty clearly separates winning Windows avatars from losing ones. That group includes Windows 1.x, 2.x, 95, ME, Vista, 8 and 8.1. Of those, Windows 95 is the only one I remember fondly, but I moved to 98 long before it got close to EOL.
• Over this set, the distribution is pretty scattered and broad. The min is 2 years, the max is 13 years, the mean is 7.25 years, and the median is 6 years. Given my preceding observation about lifespans under 7 years, does that mean Windows is rather less than more successful? Interesting question, but I don’t think the answer is “Yes.” Arguably, Windows 7 persisted because neither 8 nor 8.1 could really pick up and run with the ball.

It’s interesting to step back and look at how many versions have come and gone and how each one has had its own lifecycle. My gut feel is that Windows 10 deserves to be in the same cohort as XP and 7. I’d argue further that Windows 11 could be in the same company — but of course it’s too early to say just yet. After all, it’s only just a bit over 4 years old.
