This week Microsoft released new dynamic updates for Windows 11; updates for Windows 10 were not released this time.
For those who may not know, dynamic updates bring improvements to the Windows Recovery in the form of Windows Recovery Environment (WinRE) updates, also called Safe OS updates, as well as to the Setup 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.
Both setup and recovery updates were released but only for version 24H2 and previous versions did not receive them. The updates also applies to Windows Server 2025. The changelogs are given below. First up we have the Setup update:
