|Downgrade rights of Windows 10 Pro|
If you use the TOUGHBOOK preinstalled with Windows 7 Professional through downgrade rights of Windows 10 Pro, it can be used only for the period of time when Windows 7 Professional 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 10 Pro licensed to the device. If you wish to continue using Windows 7 Professional 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 10 Pro by the end of the support period of Windows 7 Professional.
For more information on Windows 7 end of support date, please see Microsoft’s Windows lifecycle fact sheet.
