It's crazy easy to find warezed copies of Windows 10 on U.S. Amazon ($12 for somebody to burn a DVD of their bittorrent download, $15 to add a key).
By contrast, searches on AliExpress for Windows OS in any form dead-end hard. And it's not for lack of consumer interest either; Enter "Windows" and autocomplete suggests all possible combinations of "Windows", "10", "7", "OEM", "Key", etc.
I hadn't spent too long at this because it was out of idle curiosity rather than desire. YMMV.
Within the U.S., legit (albeit greymarket) OEM Windows start at $80 on Amazon.
Taobao shows less restraint w/r/t Windows 10 warezing. US$70 buys you an OEM key, but for US$1.50 you can have somebody unlock your Win 10 installation by remote administration.
Google Translate leaves service descriptions ambiguous, so don't put a lot of trust in the above.
Ebay wins for market madness, internat'l sales of Win 10 keys and downloads are a riot of prices. US$3 and up. Mostly via UK and Canada.

Huh. I wonder if that means that MS is now mostly going after system builders.
It makes sense. You can't pirate Windows if it already came with your PC.
@suetanvil Legit OEM copies have long been a staple on the grey market. Microsoft does not approve

...but seems to abide it, or at least isn't bothered enough to come down on the vendors. After all, they're legit copies meant to be bundled with new hardware sales rather than sold separately; Microsoft is still getting revenue, albeit a little less.
Anything below that threshold (key sales, "recovery" disks, etc.) is the steep slippery slope.
