Since its launch into the public sphere earlier this year, Windows 10 has been gaining users in leaps and bounds. The data we've seen coming out from various sources, such as Net Applications, has been backed up by the US Government's Digital Analytics Program (DAP) which suggests that among Windows users, 12.4% of them are running Windows 10 - up from 8% in August.
The Digital Analytics Program is a custom version of Google Analytics that draws data from visitors accessing 3,800 websites run by the US Government. Interestingly, the DAP also shows which versions of Windows are being hardest hit by by Windows 10. The data shows that Windows 7 has lost 7% of its user share and Windows XP has lost 2.1% of its user share.
Other versions of Windows are on the decline too but they are all negligible drops, for instance Windows Vista lost only 1.6% bringing it down to just 2.3% of the total amount of Windows users visiting the U.S.' government sites. Windows 8.1 dropped to 15.7% in November, down 1.1% since Q1 2015. The data suggests that users who purposefully stuck with older - more popular releases - think that Windows 10 is a good upgrade and have started to jump ship.
