No idea about tech support since I haven't needed them. I'm not fond of M$ Windows 10 forcing some kind of account registration initially since I bought this to be a stand alone and not be hooked up to a network. It is going to run a marquee. I did spend a day using it on an internet connection just to see how it would run. No one realized it wasn't a tower system on the desk. Video does start to bog just a bit after a dozen tabs are open in Chrome. Just like everything else no matter what computer, it bogs down in Edge just as fast as a desktop. Very capable wireless. I was impressed. Once I stripped it down to a single user account altered the OS settings to allow a boot without a login it came up to the desktop and launched to startup program I had intended to run. I still need to exercise it a bit more. we have six so far with another four on order.
