IMO, MS does not do anything for free unless there is something big in it for them to do so. I suspect they either want to get some real world guinea pigs to use 10, perhaps it has not been well received and people don't like it or I suppose it could be for another reason.
My old home PC was slowly dying. I went out and bought a new laptop with Windows 8 about 6 months ago. I still hate 8 for various reasons but I have managed to live with it. If I could go back to Windows 7 I would.
Besides trying to locate some people that have it to get feedback, if I were you I would see if MS would agree to upgrade you to 10 but agree to let you go back to 7 or 8 if you don't like it.
