After installing Windows update KB3035583, you will notice a Windows logo is now present in the system tray of Windows 7 and 8.1 computers. Clicking it launches a “Get Windows 10” dialog but the tray icon will also remind you periodically until you’ve clicked it.
The dialog explains the steps to upgrading to Windows 10. You are prompted to enter your email address to reserve your free Windows upgrade for the device you are using and then told to wait until the update is ready.
You will be emailed when it is time to upgrade to Windows 10. The dialog also includes a quick overview of some key Windows 10 features and stresses that you are reserving a completely new and totally free edition of Windows, not a trial.
Once you’ve entered your email address you have nothing more to do for now. You will be emailed when more action is required and Windows 10 is ready to be installed.
Joe Belfiore took to Twitter this morning to announce that Windows 10 will be going live on July 29th. Reserving a copy with the dialog will enable you to get it on the first day.
An interesting note is that there is no immediate way to remove the upgrade tray icon. Even after reserving a copy, it lingers around, reminding you of what is around the corner. It can be removed by uninstalling the update that added it, KB3035583, though.
We have known for a couple of months that Microsoft will be aggressively marketing Windows 10 to Windows 7 and 8.1 users. Indeed, the files for this reservation assistant were discovered quite some time ago, tucked away in a Windows system folder and waiting to be activated.
There are still some questions to be answered regarding how exactly the update will be offered. In particular for PC enthusiasts, there is no clear word on whether you will be able to clean install from a CD or if you will have to upgrade from an existing Windows installation. With less than two months until launch, we can expect these questions to be answered pretty soon.
