Microsoft Confirms RTM Build for First Windows 11 Feature Update

Microsoft has quietly confirmed that the recent Beta channel build 22621 is the final version of Windows 11 22H2. The software giant also indicated that it’s planning to release the first major feature update for Windows 11 in September or October of this year.

In a Tech Community post for hardware partners, Microsoft shared some details regarding the Windows Hardware Compatibility Program (WHCP) requirements for Windows 11 22H2. The company explicitly says that “the minimum acceptable build for Windows 11, version 22H2 certification is RTM build(i.e. 22621).” Microsoft has requested its OEMs to test their drivers with build 22621.

Microsoft indirectly confirmed the release date for the next feature update for the operating system in the post. The firm noted that its OEM partners should submit their drivers before September 5 to ensure the compatibility of their devices with version 22H2. A previous report from Windows Central already points to a September or October release for Windows 11 22H2. And it’s likely that 22H2 will arrive in the same timeframe. We hope that the company will share more details about its rollout plans in the next few weeks.

Microsoft releases ISO files for Windows 11 build 22621

As a reminder, Microsoft released Windows 11 build 22621 to Insiders in the Beta Channel on May 11, with minor fixes for Voice Access, the Taskbar, as well as File Explorer. This release also removed the preview watermark, which indicates that it is an RTM build. Going forward, Beta Channel Insiders will only receive bug fixes and other improvements via cumulative updates rather than full builds.

Microsoft has also released ISO files for Windows 11 Insider build 22621. However, Windows Insiders will need to be signed in with their Microsoft account to download it from the official website.
