Microsoft has identified an issue where some attempts to reset or recover Windows devices might fail. This issue is observed after installing the August 2025 Windows security update on some client versions of Windows.

Microsoft has introduced a hardening change to strengthen the Microsoft RPC Netlogon protocol by blocking RPC anonymous requests used to locate domain controllers.
