Microsoft released today a new KB5007253 patch for Release Preview Insiders running Windows 10 21H1 and 21H2 builds. This new patch follows the release of the previous KB5007253 update two days ago, and it brings a single fix for an issue affecting Windows Hello for Business.

“We fixed an issue that might affect devices that use Windows Hello for Business and are joined to Azure Active Directory (AD). These devices might experience issues when they access on-premises resources, such as file shares or websites,” the Windows Insider team explained in the release notes. Today’s patch should be available for non-Insiders before the end of the month.

In case you missed it, Microsoft has now started rolling out Windows 10 version 21H2 to users running Windows 10 version 2004 or newer. The update will appear as an optional update in Windows Update, but users with eligible PCs may also choose to upgrade to Windows 11 directly.

Windows 10 version 21H2 only brings a couple of new features including enhanced WiFi security with support for WPA3 H2E standards, as well as simplified passwordless deployment models for Windows Hello for Business. Going forward, Windows 10 will only receive new major updates once a year, just like Windows 11.
