Windows 10 will be released on 29th July, and it’s no secret that it will be a free upgrade from Windows 7 or 8. In fact, a special icon is currently appearing in the system tray, allowing us to reserve our upgrade – possibly to spread out the download rather than have everyone hit the servers on launch day.
When you click on the system tray icon, a small application gives you an overview of what’s coming in Windows 10, and allows you to reserve the upgrade. Below are screenshots of this application (from 3 weeks ago), included here as a historical record. The application is slightly different today, but more or less conveys the same message.
