I originally installed it by updating from Windows 8 on the tablet to Windows 10 during the free period. However, the restore partition that is on it reinstalls Windows 8, so I was hoping to get rid of it at least. Also, as an update to the situation, the media creation tool doesn't seem to work since it says it can't validate the key (even though the product is activated to my account... i'm wondering if maybe it's missing some hardware like a TPMv2 chip or something, but i haven't looked into it). Plus, I've had some blue screens trying to get it into the Insider Program. My next step is going to check the disk/memory for errors, but i just haven't gotten around to it yet.
