Mine did upgrade to 17763.1, no key needed, mine was HWID activated. I used the consumer iso, the pro index will upgrade PfW.
Sorry if this is a dumb question, but when Windows 10 1809 is officially released to the public, will SVF files be available to generate full installation images from a base installation image?
