Windows 10 21H2 enters the market as Windows 11 upgrades continue.
Windows 10, 11 OS Worldwide (PCs)
There are two Windows versions named 21H2 on the market now. One is from the Windows 10 branch while the other is Windows 11. The Windows 10 variant is already on 3.7% of modern PCs, and Windows 11 has grown to 8.6% since last month.
Around 60,000 Windows 10, 11 PCs were surveyed.
Windows 10, 11 OS Worldwide History (PCs)
This is the first time in modern history when an "older" version of the OS (Windows 10 21H2) enters the market later than a newer one (Windows 11 21H2).
Note: we don't have the data for the initial rollout of the first update to Windows 10 (1511, also known as Threshold 2). So it's a straight line from 0 to the first data point we have on August 22nd, 2016.
