A new build of Windows 8.1 got leaked today, confirming that Microsoft continues work on the operating system ahead of its public launch in October.
The company has already revealed that Windows 8.1 is set to reach the RTM development phase this month, but no other specifics have been provided since then.
According to some unconfirmed reports, on the other hand, work on Windows 8.1 RTM is set to be finalized on August 23, so OEMs are very likely to get their hands on it sometime next week.
Word is that Microsoft is planning to continue improving Windows 8.1 even after it reaches RTM, as the company wants to make sure that no bugs or glitches will exist in the OS update.
Windows 8.1 will debut on October 18, but Windows 8 users will be allowed to get it as a free download from the Store a day earlier.
