Windows 10 Version 20H2 Hits 40 Percent Usage Share

Posted on April 27, 2021 by Paul Thurrott in Windows 10 with 5 Comments

Windows 10 version 20H2 is now neck-and-neck with its predecessor, Windows 10 version 2004, with roughly 40 percent usage share.

“[Windows 10 version 20H2] added another 10 percent to its share over the month of April and is now on more than 40 percent of Windows 10 PCs,” AdDuplex notes in its latest report, citing a survey of over 70,000 Windows 10 PCs. Windows 10 version 20H2 now has 40.1 percent usage share, compared to 40.6 percent for Windows 10 version 2004.

Last month, Windows 10 version 20H2 was at 30 percent usage share, and looking at the numbers, it appears that its biggest gains came from those upgrading from Windows 10 versions 1903 and 1909, and not 2004. Last month, Windows 10 version 2004 had 42.1 percent usage share, so its losses this month were minimal.

With Windows 10 version 21H1 expected by the end of May, 20H2 has one more month before it has any new competition, and I suspect we’ll see 20H2 take the top spot in May regardless. Windows 10 versions 2004, 20H2, and 21H1 are all essentially the same codebase, making upgrading between any of them a relatively simple and safe process when compared to a full feature update.

    While I was on 1909, 2004 was not offered to me at all. Finally, 20H2 was offered to me on 2021-04-18, just a few days before 1909 would no longer receive support.

    20H2 re-enabled the following telemetry aspects:

    • services DiagTrack, DiagnosticsHub.StandardCollector.Service, dmwappushsvc;
    • tasks Application Experience, Customer Experience Improvement Program, Autochk Proxy;
    • registry DataCollection AllowTelemetry, Diagtrack-Listener;
    • group policies Windows Defender;
    • circumventing firewall rules by placing SystemApps elsewhere.

    If you need to tame dmwappushsvc, create a CMD file and use sc to stop and disable it on each user's logon.

    The more trivial changes affect arrows of desktop icons, a new opt-out (sigh!) advertisement option etc.

    So what you are saying is that Microsoft's version 20H2 of Windows is up to 40% share of the last version of Windows, Windows 10.

    Is that correct?

    The more interesting number in this chart is the amount of users that are out of support or very near out of support:

    FCU, 1803, 1809, 1903

    1.8 + 1.4 + 1 + 3.3 = 7.5%

    The fragmentation of Windows 10 - "the last version of Windows" - continues.

      In reply to crp0908:

      1909 support ends in a few weeks and 2004 ends the end of the year. For a medium and big businesses even the end of the year is close.

      so that’s 18% total out of support by middle of May and another 40% by the end of the year.
