Windows 11 trying to sneak onto Windows 10 system?
Solution 1
How do I update to Windows 10 21H2 without Windows 11 sneaking in?
When notified that your device is compatible with Windows 11, simply choose the option, to stay on Windows 10. At this point, you will have to manually elect to upgrade to Windows 11.
How would you go about it?
When prompted to upgrade to Windows 11 decline the upgrade. It’s unnecessary to disable TPM support to block Windows 11. At this time Windows 11 is still an optional upgrade and Windows 10 is fully supported until 2025 so there is no reason that will change.
If you really want to make it impossible for Windows 11 to be installed. You can configure the Select the target Feature Update version
group policy to 21H2
. The first field should be set to Windows 10
while the second field should be set to 21H2
. This policy will prevent Windows Update from installing Windows 11.
Registry Key:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
"ProductVersion"="Windows 10"
"TargetReleaseVersion"=dword:00000001
"TargetReleaseVersionInfo"="21H2"
Solution 2
I have used Windows Update to upgrade to Windows 10 21H2, and Windows 11 didn't sneak in.
If Windows Update proposes "Feature update to Windows 10, version 21H2", then you are good to go.
If it doesn't, you may still download directly the upgrade from Microsoft's page of Download Windows 10, where you can choose between doing the upgrade from there, or to create a Windows 10 installation media and use it instead.
Solution 3
I used gpedit.msc to disable automatic updates and select the target feature update version, 21H2. I also set AUOptions in the registry to 2 so the system will notify me before downloading updates.

Mokubai over 2 yearsDowngrading your processor to an unsupported one worked for me...
-
Jeff Zeitlin over 2 yearsWhen it was offered to me on one of my laptops, I had the option to decline for now.
-
Hong Ooi over 2 yearsYou tell it not to install Windows 11. Seriously people

Corey Ogburn over 2 years@Mokubai When I tried to do this exact thing, it didn't work for me: pbs.twimg.com/media/FE05V8NVgAIQCvs?format=jpg&name=large

Ramhound over 2 years@CoreyOgburn - Sounds like you have a completely different question.
-
fraxinus over 2 years@HongOoi "you tell it" + "Windows" sometimes goes with "It does whatever it wants anyway". The question is pretty much reasonable.
-
Hong Ooi over 2 years@fraxinus paranoia is always reasonable to the paranoid
-
Corey Ogburn over 2 years@Ramhound, Nope, I joined the Beta preview channel because I wanted to reach the minimum build number that supported WSL+GUI and Windows 11 got installed. My processor is marked as incompatible but it installed Win 11 anyway. To be fair, it's been pretty stable.
-
Ramhound over 2 years@CoreyOgburn - Installing Windows 11 Insider Preview and the stable Windows 11 build are two very different things. You still opted into installing Windows 11, otherwise, it wouldn't have been installed. You most definitely have a entirely different question though. I also suspect
AllowUpgradesWithUnsupportedTPMOrCPU
is set to1
on your machine. My answer does not apply if you manually opted into the Insider Preview program and, elect to install Windows 11. It's also possible if you were already elected into the Beta channel thats the reason the requirements were ignored. -

Harper - Reinstate Ukraine over 2 years@HongOoi paranoia is always reasonable when Microsoft is involved. Windows has a vast history of user complaints of being slammed with major version upgrades they didn't want or expect. There has been a long running battle between manufacturers pushing updates and users not wanting their stuff broken, even with Apple - it takes constant vigilance to stop devices from auto updating. Heck, Windows would try to auto-vaccinate its users if that were technically possible.
-
Hong Ooi over 2 years@Harper-ReinstateMonica did you try to tell it not to install Win 11?
-
Carl Kevinson over 2 years@HongOoi You're missing the point. If telling Windows not to install 10 wasn't sufficient to prevent 10 from being installed, why should we trust Microsoft to honor our requests now? Maybe asking nicely not to install 11 works today, but Microsoft's history tells us they won't honor that for long.
-
Hong Ooi over 2 years@CarlKevinson when MS starts forcing Win 11 on you in 2030 or whatever, feel free to post an appropriate answer then

user253751 over 2 years@HongOoi Didn't work for people who had Windows 7.
-
Hong Ooi over 2 years@user253751 hint: support expiry date
-
user253751 over 2 years@HongOoi microsoft was secretly pushing windows 10 onto windows 7 users before support expired. People would wake up in the morning to find their computer suddenly had windows 10
-
Hong Ooi over 2 years@user253751 nonsense. people didn't know how to drive their computers

Hong Ooi over 2 yearsThis is a terrible suggestion
-
Apache over 2 years@HongOoi - Yeah I added a note to cover that. Sorry. I've (falsely) assumed most people had it disabled by the factory because that was just my experience. HP ZBook, Lenovo ThinkPad, desktop motherboards (B450, X570), all came with TPM disabled in BIOS. So in these cases, I had to enable TPM by hand only to experience the disappointment that is Windows 11.

Ramhound over 2 yearsThe upgrade to Windows 11 isn't forced.
-
Dev over 2 years@Ramhound ALL updates are forced. Windows Update will fight you to the death.
-
Ramhound over 2 yearsYet the upgrade to Windows 11 can easily be prevented
-
Hong Ooi over 2 years@dev all updates to Windows 10 are forced. Upgrading to Win11 is not. This question is based on nonsense.
-
At0mic over 2 years@HongOoi I don't think so, considering how Microsoft has forced updates to Win10, it's not unreasonable for people to be weary of it happening again. Turns out when you violate people's trust, they don't trust you.

Hong Ooi over 2 years@At0mic did you try to tell it not to install Windows 11?
