Over 300 million PCs have upgraded to Windows 10 version 2004, based on the latest usage data from AdDuplex.

“[Windows 10 version 2004] is now on more than 33 percent of Windows 10 PCs, the latest AdDuplex report notes, adding that its data is based on a survey of almost 150,000 PCs.

As you may recall, Windows 10 version 2004 got off to a slow start this year, thanks to massive compatibility and reliability issues. But usage in the new version doubled last month, from 11.6 percent the previous month to 24.1 percent, indicating that most of the issues had been resolved.

This month, the gains weren’t quite as big—usage jumped from 24.1 percent to 33.7 percent, AdDuplex says. But it’s now neck and neck with the most popular Windows 10 version, 1909, which has 34.5 percent usage. And with its predecessor, Windows 10 version 20H2 now finalized, it still has a few months to reach its usage apex. Maybe more, if 20H2 has issues too.
