Windows 7 on USB key?

[NW2013]

Did MS ever get round to selling Windows 7 in USB key format for us lowly netbook owners?

If not, if I downloaded the ISO from the net could I then buy a legitimate licence key?

I'm aware that you can download from the MS store but I'm worried that my connection will crap out mid-dowload (mobile internet) and I won't receive what I paid for, which I obviously wouldn't be bothered about with a free download.

Once you purchase it, you should get unlimited downloads with the ability to resume broken downloads.

And yes, if you were to download an ISO from some where you get the option to purchase a legit CD key after installing it without one. I would recommend you go for the first option though.

Win 7 will work for 30 days if you leave the cd-key blank

Ah, thanks guys. I'll probably go the MS store route then.
