Windows 11 is Now on Almost 9 Percent of PCs

Posted on November 30, 2021 by Paul Thurrott in Windows 10, Windows 11 with 20 Comments

The latest report from AdDuplex shows that Windows 11 has been installed on almost 9 percent of PCs out in the world, up from nearly 5 percent a month earlier.

“There are two Windows versions named 21H2 on the market now,” the latest AdDuplex report notes of this milestone. “One is from the Windows 10 branch while the other is Windows 11. The Windows 10 variant is already on 3.7 percent of modern PCs, and Windows 11 has grown to 8.6 percent since last month.”

AdDuplex also noted another interesting milestone: “This is the first time in modern history when an ‘older’ version of the OS (Windows 10 21H2) enters the market later than a newer one (Windows 11 21H2).” That’s true: Windows 11 launched in October while Windows 11 version 21H2 didn’t arrive until November.

AdDuplex surveyed about 60,000 Windows 10 and 11 PCs to obtain this data.

    Kind of shocking to be honest. Some of that is new PC's and some is upgrades.

    I can't imagine it going to grow super-fast past some point. As in I think it will hit 15% or whatever and stagnate. It has too many factors against it. It has excluded lots of hardware. Business won't be in any hurry and Windows 10 still has 3 years of support.

    My gaming PC could personally run it but I do not want to blow it away to run a buggy new version of Windows any time soon. There is nothing it will do for my gaming right now.

    I wonder if adoption is going to be somewhat slower simply because going from 10 to 11 is a harder transition, since there is a pretty radical UI change. I have three personal PCs that I use: a laptop that is my main "general use" computer, a Surface Go 2 with LTE that I use for portability, and a desktop that is mainly a workhorse for managing media and hosting VMs for development. I have done the upgrade on the Surface Go 2 and the laptop is relatively new so I just installed Windows 11 immediately after opening the box.

    Even though I'm usually an early adopter, I've been putting off doing the upgrade on the desktop since the upgrade on the SG2 was such a hassle. The main issue is the Start menu. I don't understand at all why Microsoft thought the best choice was to completely reset the Start menu on an upgrade. Even with the significant change to the UI, simply keeping everything that was pinned to the Windows 10 menu pinned to the Windows 11 menu would have made an enormous difference.

      I'm deliberately not updating my SB 2 (which qualifies) as have an old (but perfectly useable) desktop and Surface Go which can't be upgraded. Suspect quite a few in the same position

    I have 1 PC running windows 11 out of the 4 in the house. It's my new laptop that I use for remote logging into my work machine. Everything runs fine so far, giving it a month or two for some updates to come out and then plan to push all the others to 11.

    I suspect many people are used to the upgrades every 6 months and the upgrade rate will surge at some point. This is still basically windows 10, why would it not become the dominant system within a year like most of the rest have?

    Folks, the survey was only amongst Windows 10 and 11 PCs - it does not include ALL Windows PCs!

    So there is about 1billion windows 10 devices and the average number of PCs sold each year is 275million according to statistica. Let’s assume the sales rate is constant (to make the math easy). That would be about 70million pcs each quarter which is 7% of the install base. So if you extrapolate from the Ad Duplex it is saying that there are about 90 million windows 11 devices in the wild.

    the question becomes what is the sales rate of machines with windows 11 vs windows 10? My hunch is that the majority of the install base comes from new purchases and very few have decided to upgrade their current hardware. It wouldn’t surprise me if next year Microsoft starts and aggressive windows 11 upgrade push to goose the numbers.

    My personal statistics: Windows 11 is now installed on

    • 20% of all the Windows-based devices in our household (including those that can never run Windows 11)
    • 50% of all the eligible devices in our household
    • 100% of all the devices in our household on which the Windows Update offered to install it

    Unbelievable that this garbage has any market share.

    "Windows 11 launched in October while Windows 11 version 21H2 didn’t arrive until November."

    Should that be "Windows 11 launched in October while Windows 10 version 21H2 didn’t arrive until November."

  9. navarac

    Less than 9% of about 60,000. Very vague as most statistics tend to be. Doesn't mean 'squat' as usual.

    It would be interesting to see the break out of what the Windows 11 installs actually are - I wonder how many of these are 10 to 11 upgrades offered via Windows Update. I've seen that on one PC (and declined.)

  11. mikegalos

    An odd statistic since it is neither a report on new installs nor one on installed base,

    All of my machines, including my work laptop, have been upgraded to Windows 11. Loving it so far!
