The latest users that are under the microscope from Microsoft are those running Windows 10 1803 users, which is better known as the April 2018 Update. However, that version of the operating system has now reached end-of-life, which means that after this week's Patch Tuesday, it will no longer receive updates from Microsoft.
As a result, these customers will soon be automatically upgraded to Windows 10 1903, aka the May 2019 Update. This applies to both Home and Pro version of Windows 10 1803, and Microsoft indicates that it will give these users a "convenient time" to schedule the install of the major feature update. The company began the training process for these forced upgrades back in June.
"Keeping those devices supported and receiving the monthly updates that are critical to device security and ecosystem health," Microsoft writes. "If a device is out of service, it is no longer receiving quality updates from Microsoft and may become more vulnerable to security risks and viruses,” the company explained over the summer. "A single exploited device can reveal other devices on a network, revealing otherwise secure information or spreading malware to other computers in the network."
The latest version of Windows 10 is the November 2019 Update (version 1909), and it was first released to the public on Tuesday. However, it is only available to what Microsoft's describes as "seekers" that actively go to Windows Update and hit the "Check for updates" button.
