Microsoft Releases Windows Recovery Updates KB5120999 and KB5121002

Microsoft has released new Windows recovery updates for Windows 11 and Windows 10, bringing fresh Windows Recovery Environment improvements to several supported versions.

The releases arrive shortly after Microsoft pushed Windows 11 26H1 KB5120996 and KB5120998 to the Release Preview Channel.

The new Safe OS Dynamic Updates also accompany the August 2026 Patch Tuesday updates.

Microsoft releases recovery updates for multiple Windows versions

Microsoft has released new recovery updates for Windows 11 26H1, Windows 11 24H2 and 25H2, Windows 11 23H2, and Windows 10 21H2 and 22H2.

This month’s Dynamic Update release includes recovery updates only. Microsoft did not release new Setup updates alongside them.

Dynamic Updates improve the Windows Recovery Environment, or WinRE, as well as components used during Windows deployment and setup.

Microsoft designs these packages so administrators can apply them to existing Windows images before deployment. Dynamic Updates can also preserve Language Packs and Features on Demand during the update process.

Windows 11 version 26H1 receives KB5120999.

The update improves the Windows Recovery Environment and updates WinRE to version 10.0.28000.2703.

Windows 11 24H2 and 25H2 get KB5121002

Microsoft has released KB5121002 for Windows 11 versions 24H2 and 25H2.

The update includes improvements to WinRE and brings the recovery environment to version 10.0.26100.9168.

Windows 11 23H2 gets KB5120250

Windows 11 version 23H2 receives KB5120250.

After installation, the Windows Recovery Environment should report version 10.0.22621.7516.

Windows 10 gets KB5120248

Microsoft is also updating the recovery environment on Windows 10 versions 21H2 and 22H2 through KB5120248.

The update brings WinRE to version 10.0.19041.7660.

The updates install automatically

Microsoft distributes these recovery updates automatically through Windows Update, so most users do not need to download or install them manually.

Dynamic Recovery and Setup updates primarily help keep the Windows recovery and installation environment current before or during operating system servicing.
