Windows 10 usage continues to grow with those purchasing new PCs plus upgrading from prior versions of Windows 7 or 8

One in five Windows-powered devices steered to a host of U.S. government websites in March ran Windows 10, according to preliminary data.  For the first time, Windows 10 accounted for more than one-fifth of the visits to sites tracked by the Digital Analytics Program (DAP), which mines traffic to more than 4,000 websites on over 400 different domains maintained by U.S. government agencies, such as the Internal Revenue Service and the National Weather Service.

Through Thursday, Windows 10 recorded 20.2% of visits in March by Windows PCs, smartphones and tablets. That was a one-percentage point increase from February and more than two percentage points above January’s.  Microsoft has just over four months left to boost Windows 10 adoption by pushing the free upgrade to eligible Windows 7 and 8.1 devices. That deal is set to expire July 29, on the one-year anniversary of Windows 10’s launch.
