Downgrade rights of Windows 11 Pro
If you use the TOUGHBOOK preinstalled with Windows 10 Pro through downgrade rights of Windows 11 Pro, it can be used only for the period of time when Windows 10 Pro support is provided by Microsoft according to the Microsoft Software License Terms.
After the end of the support period, it is necessary to replace it with Windows 11 Pro licensed to the device. If you wish to continue using Windows 10 Pro after the end of the support period, you will need to acquire a separate license through Microsoft Volume License. However, since the provision of the quality update program including the security update will be ended, we strongly recommend that you migrate to Windows 11 Pro by the end of the support period of Windows 10 Pro.
For more information on Windows 10 end of support date, please see Microsoft’s Windows lifecycle fact sheet.
