If you are to believe Microsoft's chief Steve Ballmer, then all is A-OK so far.
"We're seeing preliminary demand well above where we were with Windows 7, which is gratifying," Ballmer said during an event to unveil Windows Phone 8, on Monday.
"Over the weekend we saw an incredible response around the globe to Windows 8 and the Microsoft Surface."
Seeing stronger demand for Windows 8, if true, is a great sign for Microsoft, given that Windows 7 has been its best selling Windows revision in its history. More than 670 million Windows 7 licenses have been sold by Microsoft in the three years that the operating system has been available.
