Which operating system is on the device?

Most devices on Back Market show which operating system (OS) is pre-installed. You can find this in the "Technical specifications" or "Everything you ever wanted to know" sections of the product page. Note that this section shows the overall OS only (e.g., iOS, Android, Windows), not the specific version.

Windows makes it easy to check your device for updates. Use Windows Update Manager to check for updates

Microsoft moved Windows 10 into extended support in October 2025. If your laptop doesn’t meet Windows 11 hardware requirements, this change affects software support, not your device’s functionality.

Your refurbished laptop met all requirements at purchase and still works as designed. You can continue using Windows 10, upgrade to Windows 11 if compatible, or install an alternative operating system that suits your needs. Compare operating system options and learn how to install them

Microsoft doesn't exclusively manufacture all Windows computers like Apple does, so compatibility varies by device.
