DAP's measurement of Windows 10 growth this month, however, was, like StatCounter's, paltry compared to the end of 2015, when average gains hovered around the 3-point mark, four or more times that of more recently.
In fact, the small increases in usage this month — based on the data from both StatCounter and DAP — were indistinguishable from the other periods of growth that Windows 10 has experienced since its July debut.
It's unclear, then, if the latest gains were due to the appearance of the Windows 10 upgrade on older PCs, or attributable to the operating system's organic ups and downs.
There are several possible reasons for the lack of usage share increases by Windows 10 since the beginning of the month. Microsoft could be serving the upgrade to a small number of Windows 7 and Windows 8.1 PCs as it takes its "phased" approach; users might be rejecting the upgrade offer; or if they do install Windows 10, they may be taking advantage of the month-long opportunity to roll back to their previous version of Windows.
Thus far, the only certainty is that the upgrade offer through Windows Update hasn't substantially moved the Windows 10 needle.
Computerworld will regularly revisit the data from analytics firms to determine if there is outside evidence of the strategy's success.
Preliminary data shows that Microsoft's effort to get Windows 7 and 8.1 customers onto Windows 10 by offering the upgrade through Windows Update was accompanied by small gains in usage share. However, that growth was similar to, or even less than, other periods of Windows 10 usage increase.
