Windows 10 may have reached 110 million devices in little over two months, but its launch has done little to halt the decline in the PC hardware market, according to Digital Spy.
Figures from industry analyst IDC suggest that desktop and laptop sales slumped by 10.8% during the third quarter of 2015, right after the OS made its debut.
Another market tracker Gartner pegs the decline at 7.7% year-on-year, which is still one of the sharpest downturns the industry has seen of late.
Factors behind the recent slump include the rejuvenated US dollar driving up prices in other territories, and the transition away from Windows 8.
Current machines that ship with the software are usually older computers that have returned to market with the latest operating system on board.
Windows 10 could give hardware sales a shot in the arm when the world's leading PC makers launch their autumn lineup with the OS preloaded.
