While the rumors are on regarding the release of Windows 11, Intel Corporation now added extra sugar to it by referring to "Microsoft Windows* 11-64 - October 2021 Update (21H2)" in one of its driver documentation hosted here.
As this is marked as "October 2021 Update (21H2)", it's quite expectable that Microsoft is going to RTM the all-new Windows 11 Operating System in the month of October 2021. Once released, it will be offered to Windows 10 users as a free upgrade if they meet the minimum hardware requirements.
