Yes I know you must first upgrade your current legit Windows install to Win 10 to be able to do a clean install. However I cant find any info on how the clean installs will work. Will M$ require you to have a MSA account so they can email you a new key tied to your hardware? Will there be generic iso's available to download like DigitalRiver with Win7? Will it be like "Media Creation Tool" where M$ will create a modified ISO with your key embedded? Is there a possibility you won't be able to do a clean install on July 29 since M$ said they aren't going to release Win10 all at once and some will have to wait a little longer to get their copy?
