Windows 10 version 20H2 is now neck-and-neck with its predecessor, Windows 10 version 2004, with roughly 40 percent usage share.
“[Windows 10 version 20H2] added another 10 percent to its share over the month of April and is now on more than 40 percent of Windows 10 PCs,” AdDuplex notes in its latest report, citing a survey of over 70,000 Windows 10 PCs. Windows 10 version 20H2 now has 40.1 percent usage share, compared to 40.6 percent for Windows 10 version 2004.
Last month, Windows 10 version 20H2 was at 30 percent usage share, and looking at the numbers, it appears that its biggest gains came from those upgrading from Windows 10 versions 1903 and 1909, and not 2004. Last month, Windows 10 version 2004 had 42.1 percent usage share, so its losses this month were minimal.
With Windows 10 version 21H1 expected by the end of May, 20H2 has one more month before it has any new competition, and I suspect we’ll see 20H2 take the top spot in May regardless. Windows 10 versions 2004, 20H2, and 21H1 are all essentially the same codebase, making upgrading between any of them a relatively simple and safe process when compared to a full feature update.
