This is a very good thing, a very bad thing or a complete and total blunder by someone. The Ubuntu desktop is listed for free download on the Windows marketplace complete with description and user reviews.
Ubuntu is listed under Bios and System Updates on the Windows Marketplace. There doesn’t seem to be any logical reason for it to be listed here. It’s neither a Bios nor system update, unless the purpose of putting it there was to keep it hidden but then that would be silly.
If someone wants to download Ubuntu, I doubt very much they would be searching on the Windows Marketplace.
