Microsoft Announces That Windows 10 21H2 Support Will End in June

Microsoft declared today that when the Enterprise and Education editions approach the end of service in June, it would stop supporting Windows 10 21H2.

Systems running Windows 10 21H2 (also known as the Windows 10 November 2021 Update) will no longer get monthly quality updates that include bug fixes or patches for recently discovered security vulnerabilities after the end-of-service date.

Customers are therefore urged to upgrade to Windows 11 or the most recent version of Windows 10 as soon as possible to protect their systems from attacks that take advantage of unpatched security flaws.

“These editions will no longer receive security updates after June 11, 2024. Customers who contact Microsoft Support after this date will be directed to update their device to the latest version of Windows 10 or upgrade to Windows 11 to remain supported.” In a Monday Lifecycle Policy statement, Microsoft issued a warning.

The following is a list of all Windows 10 21H2 editions that will no longer be supported as of June 11, 2024:

  1. Windows 10 Enterprise, version 21H2
  2. Windows 10 Enterprise multi-session, version 21H2
  3. Windows 10 Education, version 21H2
  4. Windows 10 IoT Enterprise, version 21H2

During the June 2023 Patch Tuesday, the Windows 10 21H2 Home, Pro, Pro Education, and Pro for Workstations editions also hit End of Service (EoS).

Windows 11 23H2 and Windows 10 22H2 in Wide Distribution

November 2022 saw the widespread deployment of the Windows 10 2022 Update, which is currently being distributed to all users via Windows Update. Updates that are compatible with Windows 10 20H2 or later are available for eligible devices as long as they are not set up to delay feature updates.

On consumer and unmanaged corporate Windows 10 devices, however, Microsoft will mandate the installation of the Windows 10 2022 Update until the devices are no longer supported.

"To help keep you protected and productive, Windows Update will automatically initiate a feature update for Windows 10 consumer devices and non-managed business devices that are at, or within several months of reaching the end of servicing. This keeps your device supported and receiving monthly updates that are critical to security and ecosystem health. For these devices, you will be able to choose a convenient time for your device to restart and complete the update.” Microsoft stated.

Additionally, Microsoft has begun forcibly installing Windows 11 23H2 on qualified devices that are either nearing or have already passed their end-of-service date. This occurs after computers running Windows 11 21H2 were updated to Windows 11 22H2 automatically before their end-of-service date of October 11, 2024.

One month after releasing Windows 11 23H2 (also known as the Windows 11 2023 Update) to Windows Insiders in the Release Preview Channel for enterprise testing, the firm announced on October 31.

An Enablement Package (eKB), which is part of the update process, will activate features that were provided in earlier 22H2 versions but haven't yet been enabled. You can utilize a guided walkthrough or a Windows help manual to troubleshoot any issues or faults you may run into when updating.
