Migration watch: In October, Microsoft's most popular OS continued to be Windows 7; it powered 51.4% of all Windows machines. Meanwhile, Windows 10 ran 32.8% of Windows PCs.
Windows 7 surrendered a few more users last month as its share of the overall Windows universe slipped a bit closer to 50%.
The continued weakening of Windows 7's user share - five months of declines and counting - is a promising sign, as the operating systems faces a deadline: Microsoft has set Windows 7's retirement for Jan. 14, 2020, now little more than 26 months away. The faster Windows 7 relinquishes its user share, the less the chance that businesses will find themselves running unpatched, and thus, vulnerable, machines. No one wants a repeat of the panicky last few months of Windows XP's lifespan, when companies blew through IT budgets scrambling to purge the obsolete OS.
Yet Windows 7 remains behind the pace set by XP . With 26 months to go before its April 2014 retirement, XP accounted for 49.4% of all Windows PCs, or two points lower than Windows 7's share in October. Things could be worse: In August, Windows 7 was three points behind XP's tempo. But the lack of progress in matching XP's slide toward irrelevance must be disheartening to Microsoft, which continues to sing Windows 10's praises, and even assert that Windows 7 is not only old and tired, but simply not up to the tasks required of it.
