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.

When will that be? July is a pretty good bet. If you want Windows 10 on a disc, you can probably expect that to arrive at the end of August.


Update: Windows 10 is coming July 29th.
