After Microsoft gave all customers control over when they upgrade Windows 10, the majority of users decided they didn't need a twice-annual refresh, data shows.According to metrics vendor AdDuplex, once Microsoft let users of Windows 10 Home and Windows 10 Pro determine the cadence of OS upgrades, each upgrade's increase siphoned more users from the version of 12 months before than it did from the upgrade's immediate predecessor.For example, Windows 10 version 1903 climbed from 11.4% of all versions in July 2019 to 33% in August.
Of the 21.6-percentage point increase, 20.6 points — representing 95% of the total — came at the expense of Windows 10 1803, the feature upgrade issued a year earlier.
Just 1 percentage point, or about 5%, of the declines that fueled the increase of Windows 10 1903 originated with Windows 10 1809.
