The world's largest software maker, Microsoft, has met expectations with its latest profit report.
Net income declined from $US6.6 billion to $US6.4 billion ($6.1 billion), or 76 US cents per share, but that beat analyst forecasts that centred on 74 cents a share in net earnings.
The company's sales rose 2.7 per cent to $US21.5 billion ($20.5 billion), in line with expectations.
Analysts say a mass corporate switch over from the 12-year-old Windows XP operating system - still used by many organisations because of its stability and reliability - to the newer (but not latest) Windows 7 software, because Microsoft is ending support for XP, is helping to boost sales.
"One of the biggest stories in 2013 is the business transition from Windows XP to Windows 7," Bob O'Donnell, an analyst at market research firm IDC Corp, told Bloomberg.
"There are a staggering number of machines still running Windows XP.
The IT guys have to pull the plug on those and upgrade, and most will do that by buying new machines." However, sales were dented by a 10 per cent fall in Microsoft Office revenue, as customers await the release of the latest 2013 version, expected in the next few weeks.
Microsoft shares eased to $27.06 in after-hours trade following the report, after having closed at $27.63 on the Nasdaq.
