Hi everyone! I apologize if this question has been answered before. I own an HP 8200 Elite that came pre-loaded with Win7 Pro x64 right from factory. I have already "subscribed" to that Windows 10 flag without entering my email credentials, so technically it should be upgrading in the 29th. Seeing that WZOR has released a "RET OEM" file, I was wondering if I can perform an upgrade, verify internet connectivity, and then clean reinstall without losing my activation? Or should I wait for the 29th? Once again, my PC is already pre-activated from factory. Your comments and suggestions are greatly appreciated.
