It's probably the free version of Windows 10 for devices with a screen smaller than 9 inches. I have an older version of the PIPO with Win 8 that I use on my TV.I don't know, my spider sense is tingling on this one.

If its Windows 10 S, you aren't going to be able to run any SDR applications on it without converting it to a full blown Windows 10 install, and that will probably eat up a extremely large chunk of that 32GB "ROM", which I'm assuming they mean an eMMC storage block.
