Make sure that you are using the latest updates

On the heels of the May 2021 Patch Tuesday release, Microsoft has flagged certain versions of Windows 10 that will no longer receive security updates. These include versions 1803, 1809, and 1909.

If you're currently using any of those, you'll want to update to a later version to continue to take advantage of security updates as they are released.

Given the plethora of Windows 10 variants currently in use, the above is a gross oversimplification.


Here's a breakdown of exactly which versions are impacted

For version 1803, Windows 10 Home and Windows Server 1803 will no longer be supported. Release date April 30, 2018 - Ended support November 12, 2019.

For Version 1809, all editions except Windows 10 Enterprise LTSC 2019 and Windows 10 IoT Core/Enterprise 2019. Release date November 13, 2018 - Ended support November 10, 2020.

For Windows 10, version 1909. Release date November 12, 2019 - Ended support May 11, 2021:

  • Windows 10 Home
  • Windows 10 Pro
  • Windows 10 Pro for Workstations
  • Windows 10 Pro for Education
  • And Windows Server 1909

For their part, Microsoft is seeking to make the transition as simple and seamless as possible.

Older versions still supported:

  • 2004. Release date May 27, 2020 - Ends support December 14, 2020.
  • 20H2. Release date October 20, 2020 - Ends support May 10, 2022.

And the version that is current is 21H1, which was released May 18, 2021, and ends support December 13, 2022.


Microsoft had this to say on the topic

"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. For these devices, you can choose a convenient time for your device to reboot and complete the update. This keeps your device supported and receiving the monthly updates that are critical to security and ecosystem health.

After May 11, 2021, these devices will no longer receive monthly security and quality updates that contain protection from the latest security threats. To continue receiving security and quality updates, Microsoft recommends updating to the latest version of Windows 10."


My perspective

One final point to note here is the fact that the last update for machines running Windows 10 1803 will automatically install the company's Chromium-based Edge browser, whether you want it or not. Just be aware of that fact.
