Windows 8 will get its official release in October, more than a year since the Developer Preview was first issued.
Computer and equipment makers will get their hands on the final release version in early August in order to be ready for October sales.
General availability of the revamped operating system will start towards the end of October, according to Microsoft.
The company used its Worldwide Partner Conference in Toronto this week to make the announcement.
The event also showcased Windows 8 devices from hardware partners such as Acer, Asus, Lenovo and Sony. Lenovo was again showing off its convertible IdeaPad Yoga tablet and keyboard combo.
It will all make for an interesting autumn in the tech world. Microsoft may have its Surface tablet running Windows out before Christmas. There was reportedly no official word about that at the recent event, however, it would probably have annoyed some of those aforementioned hardware companies. Microsoft has sidestepped them with Surface, which is an in-house development, but it relies on them when it comes to Windows desktop PCs and laptops.
Then there’s Microsoft’s arch-rival Apple, which is about to debut the latest upgrade to Mac OS X, and which will have one or maybe two major new mobile devices to announce around September or October, in time to steal a bit of thunder from Windows.
