Microsoft released Windows 11 KB5102558, KB5095615 Setup and Recovery updates

These updates deliver improvements like those to the setup files and also help in recovery of the OS.

This past week Microsoft released the newest preview update (C-release) under KB5095093. Alongside those, Microsoft also released new dynamic updates.

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 both recovery and setup updates were released for Windows 11. The company writes:
