After a less than dramatic start last month, usage of the latest version of Windows 10 grew even more slowly this past month.

“[Windows 10 version 2004] adds about 4.6 percent to its share this month,” the latest AdDuplex report notes. “This is less than the 7 percent it gained in its debut month.” AdDuplex surveyed almost 134,000 Windows 10 PCs to obtain this data.

With just 11.6 percent usage share now, Windows 10 version 2004 is officially off to a very slow start, which makes sense given all the upgrade blockers that are still in place. It still trails Windows 10 version 1909 (36.8 percent usage) and Windows 10 version 1903 (43.6 percent) by very wide margins.

Comparing the past two months, it’s clear too that version 2004’s gains are coming mostly at the expense of the two previous versions, which are essentially the same version and combine for 80 percent of all Windows 10 versions in use. Or, as AdDuplex notes, “As is now common, the growth in the latest update’s numbers comes primarily not from its predecessor but a version before that.”
