If you're looking to buy a Windows laptop or computer, there is a 99.99999% chance that the device will boot up with Windows 10 out-of-the-box — Windows 98, Windows XP, Windows Vista, Windows 7 (we miss you), and Windows 8 are long gone.
Users can retroactively install these versions but it is not at all recommended to go back to an older OS version due to security reasons and lack of support.
With the release of Windows 11 on October 5, 2021, Windows 10 support will end October 14, 2025, but for now, Windows 10 remains the most popular Windows OS version.
We do not guarantee that a Windows laptop or computer will come with Windows 10 Pro.
