This past week Microsoft released the non-security preview (optional) update for Windows 11 under KB5070311. The release brings lots of new features but also has its fair share of bugs, one of which has a fairly simple workaround.
Alongside that, Microsoft also released new dynamic update. For those who may not know, dynamic updates bring improvements to the Windows Recovery process in the form of Windows Recovery Environment (WinRE) updates, which are also called Safe OS updates. The dynamic updates also affect the Setup file binaries in the form of Setup updates.
These Dynamic Update packages are meant to be applied to existing Windows images prior to their deployment. These packages include fixes to Setup.exe binaries, SafeOS updates for Windows Recovery Environment, and more. Dynamic Updates also help preserve Language Pack (LP) and Features on Demand (FODs) content during the upgrade process. VBScript, for example, is currently an FOD on Windows 11 24H2.
This time only recovery updates were released for Windows 11 25H2, 24H2 (version 23H2 recently reached end of support). The updates for 25H2/24H2 also apply to Windows Server 2025. The changelogs are given below:
“KB5071844: Safe OS Dynamic Update for Windows 11, version 24H2 and 25H2, and Windows Server 2025: December 1, 2025
This update makes improvements to the Windows recovery environment (WinRE) in Windows 11, version 24H2, Windows 11, version 25H2 and Windows Server 2025.”
Microsoft notes that both the Recovery updates will be downloaded and installed automatically via the Windows Update channel. You can also avail both of them on Microsoft’s Update Catalog website: KB5071844.
