The case for biannual Windows 10 feature updates Aug 4, 2020 08:00 EDT · Hot! with 19 comments Windows 10 turned five years old this week, and after going through each feature update for the OS, I got to thinking about how Windows as a service has evolved over the years. When the OS first shipped, we didn't even know what the next update would be called; some speculated Windows 10.1. It was a couple of years before Microsoft decided on its biannual spring/fall schedule, and that was so it would align with Office 365 ProPlus. There have been 10 versions of Windows 10, and a number of them have been problematic, some more than others. However, version 1809 was the biggest disaster of them all, and it inspired some significant changes to the process. Starting with version 1903, users were no longer forced to take automatic feature updates, and then version 1909 arrived in the form of a cumulative update with no notable features.
