  • Windows 11 officially released on October 5, 2021.
  • AdDuplex has been releasing monthly reports showing survey results of how many PCs are making the jump to the new operating system, based on a sample size of approximately 60,000 computers.
  • As of November 2021, a little under 9% of said PCs have transitioned to Windows 11.

AdDuplex has been keeping a keen eye on Windows 11's market share. Before the operating system had even formally launched, the network had figures on roughly 60,000 PCs and were able to report that over 1% of them were on W11 ahead of October 5. Then, by the end of October, AdDuplex had new figures based on the same 60,000 sampling size. As of the end of launch month, Windows 11 had made it onto over 5% of surveyed PCs.

Now, the numbers for the end of November are available, and we can see that, based on AdDuplex's latest report, a little under 9% of PCs are now on Windows 11.

Normal Windows 11 controls 8.6% of the action, with Windows 11 Insiders constituting 0.3%. Windows 10 21H2 users make up 3.7% of the approximately 60,000s studied, while Windows 10 21H1 and 20H2 still control the lion's share of the market.

These numbers aren't luck-driven; Microsoft has made a concerted effort to get PC users up to speed on the fact Windows 11 exists and is ready to be downloaded. Beyond just about every PC manufacturer under the sun advertising their machine as having the new operating system onboard, the Redmond-based tech giant itself has also flexed its advertising muscles a bit to get people's attention. Though, for many, its Windows 11 marketing stunts still don't compare to what the company funded for Forza Horizon 5's promotional efforts.

  • I have an i-7, but it's not on the cpu list to get the Win11 upgrade, even though I was in the Windows Insider program and got an earlier version (and then reverted back to Win10 because it screwed up MS-Word). Now I can't get it again. Is there a way to force Win11 (assuming it is more polished now)?
  • The i7 is now 12 generations in. Only a small handful of 7th gen made the cut, so if it's 7th gen or older, you're not officially supported.
    If it's not on the supported list, it's not on the supported list, and it's a list made for a reason. Microsoft does have methods to install on "unsupported" systems though. You cannot upgrade from W10 to W11 on unsupported hardware. But here, isn't the place to be asking or getting help with that. Hit up the forums around here. Lots of info.
  • My Surface pro 2017 didn't make that cut. These numbers shouldn't be too surprising to anyone as I have no intention of upgrading, although I did buy a surface pro 8 that has it. Between hardware restictions on and secure boot I will be riding windows 10 out into the sunset on my desktop.
  • I thought Windows 11 was going to be an optional update. In our organization we had a number of Surface Pro devices that automatically upgraded over the Thanksgiving holidays without any prompting. I also thought there was supposed to be a 10-day rollback period, but that option is greyed out and unavailable. Very disappointed as it has made some of the devices incompatible with older printers we are using and now I've got to do a fresh install of Windows 10 to get them back to where they were.
