Meanwhile, the 2004 version topped the table, although the growth rate was only modest, with 42.1% of Windows 10 PCs slightly higher than 41.8% in February. The strongest was in the November 2019 update (or 1909). It was only 18.4% PCs, down from 26.8% PCs in the previous month.
Other older versions have also decreased but not significantly. The May 2019 update, or 1903, fell from 5.8% to 4.6%, while version 1809 dropped from 1.4% to 1.2% and from 1803 to 1.7% to 1, 4%. All previous versions accounted for 1.9% of Windows 10 PCs, down from 2.1% combined. On the other hand, the number of users running Insider instances increased from 0.3% to 0.5%, which can stem from the more widely available 21H1 version, both as an ISO and upon first release.
