AdDuplex: Nearly 10 percent of PCs are running Windows 11

Microsoft officially released Windows 11 for the general public on October 5, and even before we jump to December, Microsoft’s latest desktop OS has gained a sizeable market share, according to a survey by AdDuplex.

AdDuplex has released the numbers for November 2021, providing us an insight into the market share of different versions of Windows desktop OS. According to the latest AdDuplex data, Windows 11 now claims 8.6 percent(vs 4.8 percent in September) of the total Windows OS market share, while 0.3% of users are on the Windows 11 Insider Builds. Simply put, Windows 11 claims a total of 8.9% usage share.

Windows 10 21H1 update is the most popular version of the OS with a market share of 36.3%.

A close second is the Windows 10 20H2 update with a 31.8% market share. The 20H2 is followed by Windows 10 May 2020 update which is currently running on 11% of Windows 10 PCs. Windows 10 November 2021 update, on the other hand, claims a decent 3.7% usage share, while Windows 10 1909 claims a market share of 3.6%.

It’s worth noting that the AdDuplex data is based on close to 80,000 PCs running UWP store apps, therefore, it doesn’t paint the whole picture.
