    Hilariously enough I lost my legit product key and have no idea how to recover that from M$, anyways long story short used a KMS and I have no idea how to upgrade to 8.1. I've searched everywhere and can't find any thing. I was thinking perhaps I could download a 8.1 disc and do the upgrade with that like you'd upgrade to basic windows to professional. Any incite on how to upgrade without doing a fresh install?

    You can check Windows Store and upgrade to 8.1.

    Upgrading from an activated retail copy of 8 won't require your product key. If your setup is using KMS then you have to activate and upgrade using an ISO. You can find the ISO easily in this forum. And as for activation.... well, shoot off a mail to M$ and tell them the whole issue. You're sure to get back your key. VL/MAK copies are harder to crack and frankly, it makes no sense to move from a legit copy to a pirated one.
