Microsoft is usually tight-lipped when it comes to releases dates. This is a way of creating maximum flexibility in case development or launch dates are missed.
While Redmond tried to be vague with the dates for Windows 11, there have been hints, rumors and suggestions that Windows 11 will launch in October.
Intel just added some fuel to that fire.
Researchers noticed that release notes for some Intel Windows 11-compatible graphics drivers refer to a potential release date and month.
Just as Windows 10 version 2004 is also referred to in the release notes as the May 2020 Update and Windows 20H1, so Windows 11 is referred to as “October 2021 Update”.
Take a look in the OS Reference section of the release notes for Intel Graphics – Windows DCH Drivers:
Supported OS versions
Microsoft Windows® 10-64 – October 2018 Updated (1809)(RS5)
Microsoft Windows 10-64 – May 2019 Update (1903)(19H1)
Microsoft Windows 10-64 – November 2019 Update (1909)(19H2)
Microsoft Windows 10-64 – May 2020 Update (2004)(20H1)
Microsoft Windows 10-64 – October 2020 Update (20H2)
Microsoft Windows 10-64 – May 2021 Update (21H1)
Microsoft Windows 11 – October 2021 Update
Now of course this isn’t official but it strongly points to an October 2021 release.
