Whether you have opted for the free upgrade or not, Microsoft will download Windows 11 or Windows 10 to your computer. It will do so if you have the automatic updates enabled on your machine. Sure, it will ask you first, if you would like to install it, once the download is completed. But if you would like to, you can stop Windows from automatically downloading Windows 11/10 upgrade files to your computer, by modifying the Registry or Group Policy settings.
Stop automatic downloading of Windows 11/10 upgrade files
If you are a system administrator who wants to prevent Windows 7, Windows 7 for Embedded Systems, Windows 8.1, and Windows Embedded 8.1 Pro clients from downloading Windows 10 and upgrading to it – or upgrading Windows 10 to Windows 11, you can do the following.
Using Group Policy
You will first have to make sure that the Windows Update client mentioned on KB3080351 is installed on your computer.
To suppress the downloading of the Windows 10 Upgrade, press Win+R to open the Run box. Type gpedit.msc and hit Enter to open the Local Group Policy Editor.
Navigate to the following setting:
Computer Configuration/Administrative Templates/Windows Components/Manage end user experience\Windows Update
Double-click on Turn off the upgrade to the latest version of Windows through Windows Update and Enable this policy setting.
Click Apply and exit.
If you are using Windows 11/10, you may not find the aforementioned Group Policy setting. In that case, you need to use the Configure Automatic Updates setting. You must disable this setting in the Local Group Policy Editor.
Using Windows Registry
To suppress the downloading of the Windows 11/10 Upgrade, press Win+R to open the Run box. Type regedit and hit Enter to open the Registry Editor.
Now navigate to the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Give the DWORD DisableOSUpgrade a value of 1. If it does not exist, create it.
If you wish to re-enable the upgrade anytime in the future, change its value from 1 to 2.
PS: You can now decline the free Windows 10 Upgrade offer from the Get Windows 11/10 prompt itself.

How do I stop Windows 11 from automatically downloading?

Why is my PC forcing me to download Windows 11?
Microsoft forces users to download the next version of Windows (in this case, Windows 11) so that they can try more new features and options to improve and increase their productivity. As newer versions come with more features and revamped UI, it is always better to try it on your computer. However, if you do not want to use the latest version, you can stop Windows 11/10 from upgrading your computer automatically.
