Hey guys, got a somewhat unique situation and I'm wondering if anyone has had success with this. In a nutshell, I have a base image for a few work PCs that I have here, which have a bunch of tweaks and preloaded software. This base image has the Win10 Home KMS key installed, which prior to the TH2 10586 update, I would use the GenuineTicket.xml method and the retail upgrade key. This has worked fine, and still works fine. Saying that, I have a few machines here that have issues (bad disks, won't boot etc) and I'd like to be able restore this Win10 image and activate it using the attached Win7 key without installing Win7 first and running the gatherosstate.exe to get my GenuineTicket.xml file. I understand that as of TH2, it will accept (and I presume, convert) Win7/8 keys during the setup wizard, but not after the fact. Running changepk.exe to change my product key after Windows 10 has been installed will return an error saying that this licence is not valid to activate my version of Windows 10 If anyone can shed some light on this, let me know.
