Windows 10, the latest incarnation of Microsoft's popular operating system will be released in late July, one of the company's key partners has accidentally revealed.
Lisa Su, the chief executive of computer chipset maker AMD, revealed the launch date on 20 April during an earnings call with investors.
In response to a question posed by an investor, she said: "With the Windows 10 launch at the end of July, we are watching sort of the impact of that on the back-to-school season, and expect that it might have a bit of a delay to the normal back-to-school season inventory build-up."
Excitement for Windows 10 has been building for the past 12 months, particularly since the Metro user interface in Windows 8 and Windows 8.1 has been so unpopular with consumers and businesses alike.
Microsoft revealed in November 2014 that only 200 million Windows 8 licences were sold in the first 15 months after it was launched, a sharp contrast when compared with its predecessor Windows 7, which sold 240 million in just the first 12 months.
Originally codenamed "Threshold", Microsoft unveiled details about Windows 10 in September 2014 together with the technical preview of the new operating system. More details targeted specifically at consumers were revealed in January, including the Spartan web browser, holographic virtual reality headset HoloLens and the Cortana personal assistant.
Su's comments are in line with Microsoft's previous comments, which have stated that Windows 10 would be out at some point in mid-2015.
So if you are looking for a new computer or have been dying to get rid of your Windows 8 PC, you have less than 71 days to wait.
