How do I completely stop windows 11 to try to install on my windows 10 ?

so i have the last windows 10 update to this date, if you go to registry editor and follow that path to windows update, you should be able to click a drop down arrow and it should show "AU" open it and you should see "file" called NoAutoUpdate" double click it and a new window will open, should give you two boxes that are editable; value data and base, value should be 1, change it to 0, base for me was hexadecimal, i left that alone. now what that did for me was it got rid of the alert at the bottom right corner of the screen but when you check windows update it still offers to update to windows 11, but since were on the last update of 10 this seems like a good enough compromise to me.

Hello, thank you for reaching out to Microsoft Q&A.

To permanently block Windows 11 updates on your Windows 10 PC, follow these steps:

1. Click the Windows + R keys, type Regedit, and click OK.
2. Navigate to the following folder:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

3. In the right pane, double-click 'TargetReleaseVersion' registry key and change its value to 1.

Then, double-click the 'TargetReleaseVersionInfo' registry key, type 22H2, and click OK.

(If your Windows version is 21H2, replace the value data with 21H2).

4. Close the registry editor and restart your computer.
