According to NevinAs always, the report is based on data collected from 5,000 Microsoft Store apps that are using AdDuplex SDK v.2 or higher. Around 26,000 computers were surveyed and data collected during 26 March.
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.
