Security News > 2021 > November > Microsoft: Windows 10 2004 reaches end of service next month
Microsoft has reminded users today that all editions of Windows 10, version 2004 and Windows Server, version 2004, will reach end of servicing on December 14, 2021.
Customers still using end of service software are advised to upgrade to the latest version of Windows 10 or to Windows 11 as soon as possible to keep their systems secure and bug-free.
Update to Windows 21H1. Starting November 4, Microsoft designated Windows 10 21H1 for broad deployment, thus making it available to everyone via Windows Update.
Microsoft officially started rolling out Windows 10 21H1 in May 2020, but it hasn't been offered to all those checking for updates via Windows Update until now.
Redmond started auto-updating Windows 10 2004 devices to Windows 10 21H1 on June 5 and announced they have begun auto-upgrading a larger number of Windows 10 devices nearing the end of life to Windows 10 21H1 on June 22.
Microsoft released Windows 11 on October 5 for systems with compatible hardware running Windows 10 2004 or higher and had installed at least the September 2021 updates.
