The consumer Windows PC and tablet market didn’t get the boost it needed from the launch of Microsoft’s Windows 8 in the U.S. Since the Windows 8 launch on October 26, Windows device sales have fallen 21 percent versus the same period last year, according to leading market research company The NPD Group’s Weekly Tracking Service. Notebooks, which have been weak throughout most of 2012, saw that trend continue as they fell 24 percent. Desktop sales have fared better this year, dropping just 9 percent. Since its launch, Windows 8 has captured just over half (58 percent) of Windows computing device unit sales, compared to the 83 percent Windows 7 accounted for four weeks after that launch. Windows 8 tablet sales have been almost non-existent, with unit sales representing less than 1 percent of all Windows 8 device sales to date. Ouch! microsoftwindows8logo

“After just four weeks on the market, it’s still early to place blame on Windows 8 for the ongoing weakness in the PC market,” said Stephen Baker, vice president of industry analysis at NPD. “We still have the whole holiday selling season ahead of us, but clearly Windows 8 did not prove to be the impetus for a sales turnaround some had hoped for.”
