Preliminary data shows small Windows 10 gains after upgrade offered to older PCs

Gregg Keizer | Feb. 18, 2016
Usage share increases so far are very similar to previous growth spurts

Windows 10 usage has increased since Microsoft began serving the operating system as an automatic upgrade to PCs running Windows 7 or Windows 8.1, according to an analysis of data from two metrics sources.

But the growth in Windows 10's usage share so far this month has been significantly less than late last year, when it soared, probably due to new PCs bought around the holidays and the increased use of Windows 10-powered devices when people were not at work.

Two weeks ago, Microsoft confirmed that it was pushing the Windows 10 upgrade to customers running the older editions, saying at the time that the automatically-delivered bits were being rolled out in a "phased approach."

Although Microsoft declined to answer questions about how the upgrade was being presented to users, most analysts and pundits expected the maneuver to result in a major boost to Windows 10's usage share.

That share has climbed, but not a rate that Computerworld would characterize as either major or significant.

According to Irish analytics vendor StatCounter, Windows 10's global share of all operating systems posted week-over-week gains of around four-tenths of a percentage point in the first week of February, but declined after that.

(Computerworld calculated week-over-week usage share increases, then averaged those over rolling seven-day periods to smooth the irregular results, which contain spikes each weekend as people rely on home PCs — the latter are more likely to run the new OS — rather than their at-work computers.)

From Feb. 8 on — when the seven-day averages included only dates after Microsoft began serving the automatic upgrade — usage share increases averaged just three-tenths of a percentage point. That was far under the eight-tenths-of-a-point gains recorded by Windows 10 on the last two days of 2015.

Another source — the U.S. government's Digital Analytics Program (DAP) — also signaled an increase of the OS's share after Microsoft began positioning the Windows 10 upgrade on customers' PCs. DAP collects and collates visits to more than 4,000 websites on more than 400 different domains maintained by U.S. government agencies, including some, like the U.S. Citizenship and Immigration Services (USCIS), that attract non-U.S. residents. The bulk of the traffic DAP measures, however, is domestic.

By DAP's data, Windows 10's share of all Windows devices — and thus a different metric than StatCounter's, which was of all personal computers, not just those running Windows — jumped from a week-over-week average gain of just three-tenths of a point on Feb. 8 (the first date that included only those dates subsequent to Microsoft's announcement) to seven- and eight-tenths of a point on Monday and Tuesday, respectively.
