Fujitsu said the company will miss its annual shipment target for personal computers and it is blaming the fact that Windows 8 is not selling.
Fujitsu President Masami Yamamoto, 58, told reporters in Tokyo that interest in the software was weak.
He said that sales of devices running Windows fell 21 per cent from a year earlier in the four weeks after Microsoft released Windows 8 on October 26. The decrease has been fuelled by a 24 per cent drop in sales of notebook computers.
"Fujitsu doesn't plan to join its competitors that are discounting" to sustain sales, Yamamoto said. The company needs to strengthen its services in overseas markets, shifting from a product-focused approach.
But the announcement means that hopes that the release of Windows 8 helping PC sales to grow have proven groundless. Traditionally the release of new version of Windows has resulted in a boom in hardware. This is because the new software would require better hardware to run.
However with the last two versions of Windows that has not been the case. The software runs on more or less the same spec as the old hardware.
This means that people do not need a better computer to run Windows 8. In fact many of them can run it nicely on their old machines and squeeze out another few years of life.
To make matters worse for hardware makers, Windows 8 is more efficient at using hardware than Windows 7. It actually improves the older machine. If you bought a Windows 7 machine, all you need to do to make it better is move to Windows 8.
Does this mean that Windows 8 is a success? No, it most certainly doesn't. But it does mean that we should be looking a little askance at those claiming that sluggish hardware sales are as a result of a Windows 8 failure. This time really is different for Microsoft: you don't have to buy new kit in order to be able to run the software. Thus the success or not of Windows 8 just isn't going to be reflected in hardware sales in the same way as previous releases of the OS.
