Ok so I heard back from them (didn't take too long I haven't had time to response, plus I was fairly stunned by the reply I received:
No explanation, no time frame and not even whether the keyboard Windows 10 will be supported at some point. I almost can't believe this, technical builds of Windows 10 (which Microsoft have stated might be the last full release of Windows for a long time so why wouldn't you get your product to work fully with it) have been available for around a year, how can there not been drivers and software available?
I think this is completely unacceptable, not only are the drivers and software not up to date (it's not like this a product that is very old) but essentially ThermalTake is covering it up by not being open and honest with their customers that they haven't got support for Windows 10.
