A:Answer The manual does state you can downgrade it to windows 7, however the driver/software install can be the issue. I believe the manual stated (but you'd have to check the vendor site) that they have drivers for the Win 7 OS. I would assume as plug and play windows 7 is, you 'should' be ok....however, like normal, if the hardware is newer than the plug and play drivers, and the vendor site does not have them online....you'll be combing the hardware manufacturer for their software/drivers to try to get them to work on your systems. And that could lead to other issues if it's not compatible with other drivers/DLL files on the system.
Good luck
