So I'm in the business of selling laptops, and I can't activate 1703 while in audit mode. I never had any of the following problems with 1607. The general process I have, starts with a fresh VM install of 1703, then that install gets generalized and saved as my master image. That image gets deployed to a laptop-type, for drivers and software. Then it's shutdown to audit mode (not generalized again) , that final image gets deployed to that laptop-type, where it gets a functional test and activated. Trying to activate machines using Win 7 keys I get a mix of two errors - 0xC004F055 and 0xC0EA000A. Using machines with Win8+ keys in the bios, I get errors 0xc03f6504 and 8007007B. The crazy part of this, is that booting them into OOBE mode, registering a user, and then activating - absolutely no issues. Having the end-user handle activation is out of the question, I was hoping someone here might have some ideas.
