Microsoft inadvertently displayed the Windows 9 logo Tuesday when it posted a message online on Weibo, a Chinese social media site.

Microsoft China's message, which is the first official reference to the rumored operating system, included a mock-up wallpaper of Windows 9, Microsoft's latest operating system. Readers even asked Weibo if the start menu was returning to the platform.

While Windows 8 and 8.1 increased its market share in August, the adoption of these operating systems has been slow, according to the newest data collected by Internet-tracking company Net Applications.

With its most recently released operating system struggling, Microsoft seems to be gearing-up for the next edition.

Although the Windows 9 message was quickly taken down by Microsoft after it was posted, Cnbeta, a Chinese technology news site, was able to notice and report the story before it disappeared.

Online information company InformationWeek requested a comment about the post from Weibo, but a representative from Microsoft said the computer company has no details to divulge.

With windows 8 and 8.1 still in third place in the race among operating systems, it's easy to see why Microsoft is rushing to finish developing Windows 9. 

The two operating systems had a combined usage of 13.37 percent among computer users in August, increasing by 0.9 percent since its ratings in July, according to Net Applications. The gains could be attributed to a number of inexpensive new Windows-based devices on the market and back-to-school sales.

In spite of its improving status, Windows 8 and 8.1's adoption is even slower than that of Windows Vista that was released many years ago.

Earlier in the year, Microsoft also accidentally referenced a "Surface Mini" when the User Guide of the Surface Pro 3 was released.

The device was anticipated in May but was pulled out at the last minute since the tech company feared it would perform poorly in the market.
