At my work I set up an imaging script for Windows 8.1 Pro. The OS installs unactivated, then I use OEM-DM to pull the key from firmware, and I activate against it. It's pretty convenient, except I've run into a snag.. We have some older laptops with Win8 Core. If I try my script on these, it pulls the Core key and tries to activate Pro, and of course it fails. The error is kind of ambiguous, it just says the key is "blocked." Is there anything in firmware saying the version of Windows the key is for? It would be nice if I could get that first, and if it's not what I want to see, to skip to an Enterprise 8.1 key routine.
