Preventing Win 10 from Trying to Install Win 11

It's been years, it tries and tries, every few days, it'll say "Downloading Windows 11"

Then, later, "Failed to install Windows 11"

chatG says :

Method 1: Using Group Policy Editor (Windows 10 Pro and above)

1. Press Win + R, type gpedit.msc, and press Enter to open the Group Policy Editor.
2. Navigate to:

   Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update -> Windows Update for Business

3. Find and double-click Select the target Feature Update version.
4. Select Enabled.
5. Under Options, enter Windows 10 in the field for "Target Version for Feature Updates".
6. Click Apply and then OK.

I stumble upon (after I get cannot find gpedit.msc) : 

https://answers.microsoft.com/en-us/windows/forum/all/gpeditmsc-missing/cc1d05b2-457d-4aa6-839f-8136d0eddc35 which says to run a batch file containing (this, below):

@echo off

pushd "%~dp0"

dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientExtensions-Package~3*.mum >List.txt

dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientTools-Package~3*.mum >>List.txt

for /f %%i in ('findstr /i . List.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"

pause

Trying that, in the cmd prompt window, a bunch of stuff - installed, blah blah, finally, done, success, press any key..
