The Microsoft Windows 10 release date might have been accidentally "leaked" by Newegg.com. The online retailer, which is accepting pre-orders for the Microsoft operating system, listed Windows 10 pricing at $149 for the professional version, and $109 for the home edition.
This is not the first time Newegg has accepted pre-orders for a Microsoft OS. The company also pre-sold Windows 8 in 2012, according to ZDNET.
Microsoft has done well keeping the Windows 10 rumored release date and price lists a top secret. In March the tech giant announced via Microsoft Vice President Terry Myerson that it would launch its new computer OS sometime this summer.
Last month was Microsoft's Build Developer Conference. Web developers were disappointed that the company made no big announcement about the Windows 10 launch date.
If Newegg's Windows 10 leak is correct, it verifies Myerson's comments about the timeframe of a Windows 10 release. The new OS could be in-hand within three months.
Microsoft has declined an official comment about the possibility of a Windows 10 leak by Newegg. However, a company spokeswoman confirmed the software's planned summer launch.
Windows 10 will be a free upgrade for users of Microsoft 7 and Windows 8.1, according to CNET. It will be compatible with every computing device, ranging from smartphones to desktops.
However, the "free" upgrade to Windows 10 is not crystal clear. For example, there is a big question mark about whether Microsoft will offer it to users without an official license, or if PC builders would qualify for a full package.
PC manufacturers and software developers are waiting in great anticipation of Windows 10, due to declining sales. Intel, the world's biggest microchip maker, reduced its outlook for quarter revenue by almost $1 billion.
Windows 10 will look and function like Windows 7, with a focus on the Start Menu. It will also feature live tiles for email and Skype, as well as social media squares for Facebook and Twitter.
The first ever Microsoft operating system was Windows 1.0, which was released in November 1985. It was officially supported until Dec. 31, 2001.
