Microsoft Releases KB5068164, KB5067017 & More As Final Windows 10 WinRE Updates

Microsoft has released the final set of Windows Recovery Environment (WinRE) updates for Windows 10. The updates, part of October’s Patch Tuesday rollout, have been released under multiple KB identifiers, including KB5068164 and KB5067017, and apply to versions 21H2 and 22H2.

According to Microsoft, these updates automatically install Safe OS Dynamic Update (KB5067017) on a running PC, improving recovery reliability and setup behavior. The changes mainly target the Windows Preinstallation Environment (WinPE), ensuring a smoother recovery experience. If WinPE fails to launch an application, it will now display a message box instead of opening a debug command prompt, which should make troubleshooting less confusing for users.

Alongside these two key updates, Microsoft has shipped additional Safe OS Dynamic Updates for older systems:

• KB5067016: Windows 10 version 1809, Windows Server 2019
• KB5067015: Windows 10 version 1607, Windows Server 2016
• KB5067018: Other supported Windows 10 editions

The updates are part of Microsoft’s routine Dynamic Update packages. These help maintain language packs, Features on Demand, and other content during system upgrades, ensuring consistency for IT admins and enterprise environments.

This release also coincides with Windows 10’s final Patch Tuesday update under KB5066791, which officially ends regular support for all editions of the OS. The Recovery and Dynamic Updates are now available through Windows Update or can be manually downloaded from the Microsoft Update Catalog.
