I just got it because a previous different Amazon certified died in a week. After I use it more I may revise my review.The keyboard was better than some and is apparently needed to unpack Windows software. My wireless keyboard wasn't recognized. I later installed a Bluetooth keyboard and it working fine. The Windows version included is the latest and is Pro 64 bit. And it was very well packed for shipping.Windows says the CPU isn't good enough for Win 11.So far it seems to run well. But I chose this unit thinking it had the SD card slot as in the photo so that is disappointing. Shipping took over a week.
