Microsoft is ending support for Windows 10 version 1903 later this year. The company on its support page confirmed Windows 10 1903 will reach the end of service on December 8 2020.

This applies to 1903 versions of Windows 10 Home, Windows 10 Pro, Windows 10 Pro Education, Windows 10 Pro for Workstation, Windows 10 Enterprise, Windows 10 Education, and Windows 10 IoT Enterprise.

The end of service essentially means these versions will no longer receive security updates after December 8. Users who wish to receive an update after this deadline will be directed to the latest version of Windows 10 to remain supported.

Microsoft had released Windows 10 version 1903 in May last year. The version is running on a large number of PCs. According to a survey, about 33.5% of PCs surveyed will still on 1903. The new Windows 2004 version, however, is gaining popularity. The survey said that 24.1% of PCs surveyed had embraced the new version.

Apart from 1903, Microsoft is also ending support for older Windows 10 versions. For instance, Windows 10, version 1809 will reach the end of service on November 10 2020. The Windows 10, version 1709 will stop receiving support by October 13 2020.

Separately, Microsoft is making a major change to how it updates Windows OS. According to a recent report, Windows 10 may receive only one major update in a year. Currently, Microsoft rolls out two big updates each year.

“Feature updates will be released twice a year for Windows 10 via the Semi-Annual Channel, targeting March and September annually. Updates are cumulative, with each update built upon those that preceded it; you should always install the latest feature update (version), before your current version reaches the end of service, to remain supported by Microsoft thru monthly quality updates,” according to the company’s Windows lifecycle fact sheet.
