I went to the Microsoft linkHow to reserve your free upgrade to Windows 10
That article advised you had to have KB3035583 update so I clicked on the link provided and then went to my Windows Update and it was there. I installed it . Article said after installation I should see pop up in notification area of taskbar to get Windows 10 (see screenshot).
Nothing happened. I did not get this pop up, so how do I reserve a copy of Windows 10?
