Perhaps the biggest issue with Windows 8 was that business customers were confused by the dual interface, and they don’t like drastic change.
The odd dual interface of Windows 8: Metro and Desktop In both cases, these operating systems show that the humble PC is still important to both Microsoft and Apple, and by association the entire consumer and enterprise PC industry. In a similar vein, this past summer Apple put OS X Yosemite (now shipping) out as a public beta for the first time in years, perhaps with similar goals. It will enable the company to gather a huge amount of feedback and give a long lead time for end users and IT departments to check out the evolution of the interface. In an effort to right the wrongs of Windows 8 on the desktop, Microsoft has put the Windows 10 Technical Preview out there for anyone to download and use, unusual in that such an early release is typically available only to developers. The new Metro UI alienated and confused traditional desktop users, and many businesses chose to upgrade to Windows 7 instead or not at all. By previous Microsoft OS sales standards, though, it’s not a great success. Unloved does not mean unsold, however, as it has shipped over 250 million licenses due to being bundled on most new PCs and upgrades to the huge installed base. Everyone knows even longtime Windows fanatics do not universally love Windows 8.
