Can I downgrade to Windows® 7?

The Cintiq Companion has been designed and tested for Windows 8.1 Technically, Microsoft allows Windows 8 Pro to be downgraded to Windows® 7 Pro without charge. Customers may do this by themselves, although the assumption is that the customer (usually a company) will have Windows®7 installation disks on hand. Cintiq Companion Intel® Core™ i7 with Intel® vPro™ technology (DTH-W1310E) configuration will have Windows®7 pre-installed. The process to downgrade is somewhat complicated and more information is available here:
