Microsoft this week has released a new dynamic update for Windows 11 26H1, 25H2, and 24H2, under KB5079463 and KB5079471.
Earlier today, Microsoft released an emergency hotpatch update KB5084597 on Windows 11 25H2 and 24H2 LTSC, which patches a trio of critical network security vulnerabilities. This was released soon after the latest monthly Patch Tuesday update which is said to be causing a variety of issues for users.
Alongside that, Microsoft also released corresponding new dynamic updates for Windows 11. 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. 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 and with the usual generic changelog that does not go into much about what the update has actually done. The company writes:
“KB5079463: Safe OS Dynamic Update for Windows 11, version 26H1: March 10, 2026
This update makes improvements to the Windows recovery environment (WinRE).
KB5079471: Safe OS Dynamic Update for Windows 11, versions 24H2 and 25H2: March 10, 2026
This update makes improvements to the Windows recovery environment (WinRE).”
Microsoft notes that both the Recovery and Setup updates will be downloaded and installed automatically via the Windows Update channel.
