Microsoft has released today the June 2021 Patch Tuesday updates for all supported versions of Windows 10, including the freshly-released version 21H1 of the OS. The same KB5003637 patch is available for Windows 10 users already running Windows 10 version 21H1 (that includes Windows Insiders in the Beta and Release Preview channels), as well as users still on the older versions 20H2 and 2004 of the OS.
The detailed releases notes for this KB5003637 patch are not available yet on Microsoft's support website, but the post on the Windows Insider blog mentioned the following improvements:
Security updates to the Microsoft Scripting Engine, Windows App Platform and Frameworks, Windows Input and Composition, Windows Management, Windows Cloud Infrastructure, Windows Authentication, Windows Fundamentals, Windows Virtualization, Windows Kernel, Windows HTML Platform and Windows Storage and Filesystems.
If you have to see the option to install Windows 10 version 21H1 on your PC, don't worry as Microsoft is still throttling up availability to ensure a reliable download experience for all users. However, the company recently noted on its Windows 10 Health Dashboard that it has started pushing the update to some PCs running Windows 10 version 2004.
"We also started the first phase in our rollout for machine learning (ML) training, targeting devices on Windows 10, version 2004 to update automatically to Windows 10, version 21H1. We will continue to train our machine learning through all phases to intelligently rollout new versions of Windows 10 and deliver a smooth update experience," the company explained.
If Windows 10 version 21H1 was a pretty minor update that only brought improvements for Windows Hello and Windows Defender Application Guard, Microsoft is expected to reveal the next generation of Windows on June 24 during an event featuring CEO Satya Nadella and Chief Product Officer. It remains to be seen if a Windows 11 announcement is in the cards, but we're looking forward to seeing the company clarify what's in the pipeline for Windows 10 users.
