When is Windows 10 version 21H1 going to be released?

Windows 10 version 21H1 is the next feature update for Microsoft's Windows 10 operating system, but when is it going to be released? Short answer: The Windows 10 version 21H1 update was released on May 18, 2021.

While that may be disheartening for users and administrators who are looking for a definite answer, hints and information provided by Microsoft may help pinpoint the release date.

Microsoft calls Windows 10 21H1 the May 2021 Update. If you are new to the Windows world, you may take the May 2021 part as confirmation that the new version will be released in May 2021. While the use of a month is usually a good indicator that the operating system version will be released around that time, the name of the month has not always been the month in which the feature update got released.

The October 2018 Update for Windows 10 was released in November for instance. Usually though, updates do get released in the same month. The May 2020 Update, also known as Windows 10 version 2004, was released on May 27, 2020, and the May 2019 Update on May 21, 2019.

The update in question has the ID KB5000736. It is an enablement package, which means that it will enable the features of the feature update on the system.

The update is already available as MSU files. Most may want to wait for the official release announcement by Microsoft and official release though.

Here are the links:

windows 10 version 21h1 feature update

All information point to a release of Windows 10 version 21H1 in the coming weeks. A May 2021 seems the most likeliest, the second most likeliest is a release on the June 2021 Patch Tuesday. The latter would coincide with a remark by a Microsoft engineer in a Chromium commit in which a a June 2021 release date was mentioned. The commit was edited shortly thereafter though.

Windows 10 version 21H1 is a smaller feature update, one that will install quickly on devices running Windows 10 version 2004 or 20H2. Devices that run older versions will take longer to update though.

The update will be pushed out to devices over time. Microsoft uses the method to pick up potential issues early on and address them while the update is still in the rollout process. Critical issues may stop the distribution of the update until they get fixed.

Now You: do you run Windows 10? Will you install the new update asap?

    I myself prefer to wait a while to see what happened with the installment of 21H1 on other systems. Also, I like the read-up first what the support groups and technological websites like ghacks.net are mentioning about it.
    So it could be that I am waiting a month (Or even longer) or two before I upgrade the o.s.

      I’ll wait until July. There is no rush about upgrading anything as long as my machine is still working as usual.

    Back when XP, Vista and 7 were the most popular Windows versions with Windows 7 being the latest, I used to be excited about updates, now I just hope they don’t break something or ruin Windows 10 even further.

    All I want now is to see what their visual redesign is going to be and will they really put in effort to make it look the same across the board or will it still have that 16-bit color folder Offline Web Pages in C:\Windows\

      I don’t think that’s even 16-bit. Looks more like 8-bit. I remember having a “high color” 16-bit monitor in the late Nineties, and they looked good. The banding wasn’t so glaringly obvious until I’d tried a “true color” 24-bit monitor. 16-bit is hard to distinguish from 24 or 32 at such low resultions. So, realistically, the legacy resources you’re complaining about as being ugly are actually from WinNT and 9x, a quarter century ago.

        That directory is still there in my Windows folder but it is now empty after the 21H1 upgrade. I don’t know if it was empty before.

        It will probably still be there in Windows 50 in the year 2042 and it will probably still look the same while some other parts of the OS look modern and other outdated.

        Bear in mind that Windows 10 is still NT.

    Just updated to Version 21H1 (OS Build 19043.985) via the “Windows 10 version 21H1 via Enablement Package for 64-bit.” Update including reboot took under 60 seconds.

    What are those above provided links for? I installed the x64 one, which is an update of 167 Kb size only, but nothing happened after reboot the system, nor upgrade was offered neither. :[

    John G…. I ran the 64-bit MSU, top one, and checked my system build info which is easy to find on your PC, and it had changed to:

    Edition Windows 10 Pro
    Version 21H1
    Installed on ‎5/‎27/‎2020
    OS build 19043.985
    Experience Windows Feature Experience Pack 120.2212.2020.0

    No flashing lights or horns… just a smooth update.

      I expected something more, however it seems that only this update only changes the version number. Anyway, it’s the easiest upgrade ever done by Microsoft in his history. :[

    I installed that linked update, took literally 20 seconds. Now my coffeemaker broke and it started raining. Coincidence?

    You write:”Windows 10 version 21H1 is a smaller feature update, one that will install quickly on devices running Windows 10 version 2004 or 21H1.”

    I believe you meant to write: “Windows 10 version 21H1 is a smaller feature update, one that will install quickly on devices running Windows 10 version 2004 or 20H2.”

    Aternatively known as pushing updates onto the unsuspecting public and waiting for excreta on whirling metal to indicate a need for code review.

    I am eager that Windows 10 update release earlier but I will wait for more than 5 weeks later to install to my systems because I had a bad experience with Windows 10 crashed my systems. It is better for others to test out first than me having those nightmares.

    Just ran the 32-bit msu on nine Windows 10 32-bit systems (Home and Pro)…
    Like everyone here says…Takes a minute…No issues on any of my older systems…

      I think it means that this enablement pack allows you to receive cumulative updates for 21H1. :]

      Awesome! Curate that keyword experience appropriation narrative trigger! You’re right, no one cares. Drank far too much of the Kool Aid, Fluffy.

    No.

    Btw I am now offended that your are offended by something really superficial no one cares about. Do not patronize for someone else. They can speak for themselves if they really have a problem with such things and do not need you for that.

    Please leave with your agenda. Thank you.

    gee I don’t know why this article about when MS will release 21H1 had to be posted

    the official 21H1 ISOs just came out today 5/18 as noted by this deskmodder article:
    https://www.deskmodder.de/blog/2021/05/18/windows-10-21h1-die-offiziellen-isos-sind-jetzt-da/

    so it seems the 18th is the day

    The ISO’s out:
    https://www.microsoft.com/en-us/software-download/windows10

    The 21H1 ISO being released means almost nothing for 99.99% of Windows users, most of whom maybe only know they have Windows, might be 10, 11, iPhone, who knows?!

    Nothing in it I want, just more junkware to remove, disable or block. Beside Windows we haven’t used any MS software in a decade.
