Microsoft is planning an event to showcase Windows 9 on September 30th in San Francisco. The technical preview should be available soon after the event for people to check out. Should be interesting to see what Microsoft has in store for us other than UI changes.
Additional changes are expected to be pushed regularly to Windows Technical Preview users until the operating system is complete and ready for release next year. We understand Microsoft is planning more UI changes to the desktop, and a number of those improvements aren’t ready for the preview just yet.
