Hi guys, want to ask about my current windows key. I've upgraded to windows 10 Technical preview from a legit windows 8.1. Previous builts didn't encounter any problem, but the latest built says that my key is blocked, asking me to activate legit windows key. I've checked out windows forum, admins are providing keys for technical builds, will using those keys affect my legit windows 8 key after the official release? Or I can simply use those provided temporarily?
