Over the last couple of weeks,
Microsoft began advertising Windows 10 to existing
Windows 7 and Windows 8.1 users. Those who are regularly up to date via Windows Update should now have the option to reserve a copy of Windows 10 via the system tray, which will put you in for pre-downloading Windows 10 before July 29th. Earlier this week, Microsoft released another update for Windows 8.1 users, which puts reserving Windows 10 at the forefront of Windows, literally during the Windows 8.1 setup process and even before reaching the desktop.
This new update allows users to reserve Windows 10 within the OOBE (out of box experience) when first booting a new install or setting up a newly purchased PC. The ability to reserve comes after you setup your account, but before you even reach the desktop. This means that new users who recently purchased a
Windows 8.1 device simply can't miss the chance to reserve Windows 10. This also appears if you clean install Windows 8.1 with November Update roll-up and are connected to the internet.
