Microsoft: Windows 10 21H1 reaches end of service next month
Microsoft has reminded customers today that all editions of Windows 10 21H1 (also known as the May 2021 Update) are reaching the end of service (EOS) next month.

Today's reminder comes after two other warnings issued since September that this Windows version will reach its retirement date on December 13, 2022.

Windows customers should upgrade to the latest release as soon as possible to avoid exposing their devices to attacks exploiting unpatched security vulnerabilities since Windows 10 21H1 will no longer receive security updates.

"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 end of servicing," Microsoft said.

"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."
