Hi, I have been waiting awhile and have deemed it safe to upgrade to windows 10 from windows 7 on my desktop after using it on my laptop, and the upgrade is still unavailable, I'd think by september 15th, the demand wouldn't be big enough for my free upgrade to still be "on its way". I don't have a dvd drive or a 4 gig thumb drive (I do however have a few extra hard drives I'm willing to use to mimic a dvd drive if all else fails), but I was wondering if I'm doing something wrong here or if someone else is experiencing the same issue.
