The world’s largest software company had earlier said Windows 10 would be released this “summer.”
Touch-friendly Windows 10, which features the return of the Start menu and will run across PCs, tablets, and smartphones, is Microsoft’s latest attempt to win over mobile users and features a new browser called “Edge.”
It will be offered as a free upgrade to users of Windows 7 and 8.1, a strategy announced in January designed to capture as many users as possible.
Microsoft also said new PCs and tablets running Windows 10 would go on sale July 29, while Windows 10 for other devices such as smartphones would be available later this year.
This weekend, the software reseller Newegg leaked pricing details for OEM copies of Windows 10 and Windows 10 Pro — and even started taking preorders. The listing said these copies — for computer manufacturers and companies that build computer systems — would go on sale on August 31.
ZNet discovered two OEM System Builder packages for sale, with Windows 10 being offered for $109.99 (about £72) and Windows 10 Pro for $149.99 (£99).
