PowerShell 2.0 removal in Windows

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.
