The information is said to come from Andreas Diantoro, who, according to his LinkedIn profile, is the president of Microsoft Indonesia. According to the source article, Diantoro said that for users upgrading from Windows 8 to Windows 9, the upgrade will be free. Just like we heard back in late June, Microsoft is hoping to move all of its users to its latest platform, and by removing the cost of entry, this should be a big motivator. The comment is said to have come from a meeting that took place on the 25th of September at the Hotel Mulia, Jakarta.
