All around the world, Windows users are discovering a new icon in their notification trays — an offer to reserve a free copy of Windows 10. Sounds too good to be true, yes? Except Windows 10 actually is a free upgrade, and this really does appear to be the way you’ll get it.
Click on that icon, and up pops a description of how the upgrade process will work. (Were you hoping you’d get to download Windows 10 today? Sorry, this is just the reservation process.) Give Microsoft your email address — or not — and then Windows 10 will automatically download to your computer once Microsoft pulls the trigger.
Update: Windows 10 is coming on July 29.
