I know the question sounds confusing. Please let me clarify. The problem: I manage more than 30 PC's currently running Windows 7 (all legit licenses) that apparently quality for Windows 10 upgrade. I want to upgrade them all, but want to do clean installation. So I can upgrade one of them first, after the upgrade Windows 10 will become activated and the PC's hardware signature will be "registered" to the MS activation server. Now I can do a full clean installation and PC will activate automatically because it's already registered. Then I can install and configure all software and drivers. Finally I make a clone image of this system. *However*, if I deploy this image to the other PC's right now, they won't activate, because they have not gone through the "7 to 10 upgrade" process to have their activation registered with MS. This means I have to go through the upgrade process on each of the 30 computers that will take a long time and can be subject to issues (due to certain reasons and limitations I cannot simply have them all upgrade at the same time). So my question is, is there a way to make a Windows 7 PC "register" itself with MS's activation server without going through the full and lengthy upgrade process, so that I can then immediately deploy a cloned clean Windows 10 image and let it self-activate? Does Microsoft's "Reserve Windows 10 Icon" utility actually register the PC's signature in Windows 10's activation server at the time of reservation, or only after full upgrade install is completed? Your advice will be greatly appreciated.
