The Windows 8 home menu…which might see some big changes.

Windows 9 has not been officially announced, although we expect Microsoft to reveal the next version of their Windows operating system during a widely rumored press event scheduled for tomorrow, September 30. But in the meantime, the president of Microsoft Indonesia has reportedly spilled early details on an upgrade program for current Window 8 users. According to Indonesian site Detik (via PCWorld), Andreas Diantoro confirmed that “Windows 9 will be a free upgrade for all Windows 8 users.”

His full quote, translated by the handy but not entirely perfect Google Translate was: “Easy, when the OS (Windows 9) was launched later, users who have been using Windows 8 just need to do the update via his device. It will be installed automatically.” He reportedly made this comment at the Hotel Mulia in Jakarta.

A US Microsoft representative said that they have nothing to share at this time. But we’ll keep you updated on the further details as they’re made available, as well as what this could mean for PC gaming. On a related note, Microsoft’s Head of Xbox, Phil Spencer, talked about renewing the company’s focus on PC gaming earlier this year at E3.
