Microsoft is now rolling out this year’s second last security update for Windows 10 version 2004 or later. The update is rolling out via Windows Update. Additionally, Microsoft has also published direct download links for Windows 10 KB5007186 offline installers.

KB5007186 is part of the company’s usual Patch Tuesday cycle, which is a popular term for the day when new security updates are released for Windows.

Windows 10 version 2004 reaching the end of support

It’s worth noting that Windows 10 version 2004 will reach the end of service in December 2021 and those still using it will be automatically updated to version 21H1 or 21H2 whether they like it or not.

Early next year, we’re expecting Microsoft to forcibly install Windows 10’s latest updates on devices running certain outdated versions. By early 2021, most users of version 2004 will be required to download and install version 21H1 or newer. If you’re using an unsupported PC, you will be notified of the end of service via a notice on the Windows Update.

November 2021 Update is around the corner

As mentioned at the outset, Windows 10 November 2021 Update (21H2) has cleared the final stage of testing and it is set to land in the production channel in a few weeks.

November 2021 Update isn’t going to be a big update as Microsoft’s focus is entirely on Windows 11. However, you’re actually going to get some new features when you upgrade to version 21H2.

Microsoft says the next feature update for Windows 10 will enable support for the WPA3 H2E standard, which is a new and enhanced Wi-Fi security. Additionally, Microsoft is also bringing a new deployment method called cloud trust to enhance the experience of Windows Hello for Business. This change would result in passwordless deployments.

For consumers and developers, Microsoft is enabling GPU compute support in the Windows Subsystem for Linux (WSL).
