Hello @Cheol-Hwan Park
Microsoft is not forcing any Windows 10 users to upgrade to Windows 11. The workaround around this time to Block the Windows 11 Update is using Registry Editor.
In the Run box, type the following and press Enter.
regedit
When the Registry Editor opens, from the sidebar to the left, navigate to the following directory:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Here you can edit the registry as per the above article and stop the update. You can keep following this thread so that you can get updated if there are any new methods to stop the update.
Hope this resolves your Query!!
