Windows 8.x has not, and never will be, adopted by the enterprise and small and medium businesses. The only reason it has sold at all is because it has been foisted on a hapless and ignorant public by big-box retailers beholden to Microsoft.
The primary offerings of business class PCs from Dell, HP, Panasonic and Lenovo still offer Windows 7 Pro as the default OS option. Windows 8.x consumer PC sales for Dell were so abysmal that Dell was forced to re-offer Windows 7 on most of their consumer models.
Windows 8.x has still not achieved the penetration at this same time period as Vista did at its equivalent release point, Vista being one of the worst operating systems (until Windows 8.x) ever released by Microsoft
Windows 8.x has been a significant factor in the plummeting of PC sales since its release, and because of the monumental disaster of Windows 8.x for all PC vendors, they are currently desperately searching for alternatives to Microsoft products (such as dual-boot Android/Windows 8.x devices), having lost faith in both Microsoft’s management and Microsoft’s products.
Bullshit! It will be adopted, after they recover from having to deploy Win 7 and can justify the cap/nix to run multi-million dollar projects. That doesn't happen overnight and will not be seen in stats about Win 8 usage for years.
"Windows 8.x has been a significant factor in the plummeting of PC sales since its release,"
Not true, the biggest driver of lack of sales of PCs is tablets, smartphones, cheap price ($39 at rollout) and compatibility of this OS with older hardware (you don't need a new PC like you would for Win 7).
"Last week, Gartner issued a report titled "Windows 8.1 Could Become What Windows 8 Should Have Been," which concluded that Windows 8.1 will fix many of the problems with the troubled operating system."
... "Most importantly, it recommends that any business that was only considering Windows 8 for touch devices, should also look at Windows 8.1 "for broader deployment," in other words, on traditional PCs as well."
"and traditional computers -- will decline only slightly over that time, because of an uptake in Windows-based smartphones, tablets, and ultraportables."
