Microsoft has announced that the successor to its Windows 7 operating system, Windows 8, will be released by the end of 2012.
In a blog post on its Dutch website, a Microsoft blogger mistakenly said that it had started work on Windows 8 and that it would be released in the next two years.
The posting was first spotted by Winrumors and, so far, the company has released any comments concerning the announcement.
The company had no intentions of revealing this information and the blog post was edited within hours of Winrumors reporting it.
Microsoft has remained unusually quiet about the successor to Windows 7, which was launched two and a half years after release of Windows Vista.
The post has been edited to say that the company is working on the first service pack of Windows 7 and that the first update to the newly launched Windows Live Essentials for Windows 7 will be released in June next year.
