To use prior versions of Windows on devices currently running a newer version, it is possible for customers to obtain a license for downgrade rights. These downgrade rights will vary depending on whether the software was acquired via Volume Licensing, Original Equipment Manufacturer (OEM), or Full Packaged Product (FPP). To learn more about these rights, review the downgrade rights licensing brief. Prior versions of Windows have limited support when running on new processors and chipsets from manufacturers like Intel, AMD, NVidia, and Qualcomm. For more information, please see Microsoft Lifecycle Policy. A device may not be able to run prior versions of Windows if the device hardware is incompatible, lacks current drivers, or is otherwise outside of the original equipment manufacturer’s (OEM) support period.
