The latest AdDuplex report shows that Windows 11 is now in use on 19.3 percent of all supported PCs running Windows 10 or 11.

“While the data in the chart is real, it doesn’t really matter today,” the report notes, citing current events. “What matters is helping Ukraine in the fight for its future. Please, donate here or help in any other way you can. Thank you!”

Windows 11 is now in use on 19.3 percent of all Windows 10/11 PCs, up from the 16.1 percent it obtained in January.

Windows 10 version 21H1 is still the most-used supported version of Windows, with 27.5 percent usage, down slightly from 28.6 percent usage last month. But there was a huge change at the number two spot. Now, Windows 10 version 21H2 is the second-most-used Windows version, with 21 percent usage (up from just 12.1 percent a month ago). And usage in Windows 10 version 20H2 has fallen dramatically, from 26.3 percent a month ago to 17.9 percent.
