8:49PM EST November 27. 2012 - SAN FRANCISCO — Microsoft has stepped up to prove naysayers wrong on early Windows 8 adoption.
Tami Reller, the software giant's new co-chief of the Windows division, told a Credit Suisse investor conference in Arizona on Tuesday that Window 8 upgrades are outpacing Windows 7 in its first month.
"The journey is just beginning, but I am pleased to announce today that we have sold 40 million Windows 8 licenses so far," she said in a presentation.
Microsoft's long-term outlook as operating system leader has come into question as PC sales slacken amid a consumer frenzy over tablets and smartphones from the likes of Apple, Samsung, Google and Amazon.com.
Windows 8 became available Oct. 26, but doubts about its extreme makeover raised uncertainty about its commercial appeal to big businesses. The Window 8 debut has required a major overhaul of both the software and company in a bid for mobile relevance.
This month, Microsoft reorganized its Windows unit that resulted in the departure of long-time veteran and Windows chief Steven Sinofsky.
Microsoft executives Reller and Julies Larson-Green were tapped to lead the division.
