(Update: This post was updated to clarify that the change was Enabled by Default on Windows Server 2025 in May 2025 and to add information about how to configure this change.) Microsoft has introduced a hardening change to strengthen the Microsoft RPC Netlogon protocol by blocking RPC anonymous requests used to locate domain controllers. This change was Enabled by Default in the May 2025 Windows security update for Windows Server 2025, and in the July 2025 Windows security update for all supported versions from Windows Server 2008 SP2 through Windows Server 2022. This change is configurable by policy after installing the August 2025 Windows security update. See the article, KB5066014—Netlogon RPC Hardening (CVE-2025-49716), for details.

Windows PowerShell 2.0 is removed from Windows 11, version 24H2 starting with the August 2025 non-security update. It’s also removed from Windows Server 2025 starting with the September 2025 security update. Windows Insider preview builds already reflect this change as of July 2025. Windows PowerShell 2.0 is over 14 years old, lacks many security enhancements of the later versions, and has been deprecated since 2017. By using the newer and supported PowerShell 7 or PowerShell 5.1, you can help ensure that scripts run safer. If you have legacy scripts or software that explicitly depend on PowerShell 2.0, you’ll need to either update them or use a workaround to prevent disruptions. When will this happen: 2017: PowerShell 2.0 was deprecated. July 2025: PowerShell 2.0 is removed from Windows Insider preview builds. August 2025 Windows non-security update: PowerShell 2.0 is removed from Windo
