When I run the OEM Product Key Tool under Windows 10 64 Bit I get this message: "Unable to open MSDM table!"
That just means that you don't have an embedded key.
If your key is hashed in the OS (as it will be if you installed Windows yourself), there are many apps you can find with a web-search, which will un-hash it back to the box key.
OEMs can burn the key into firmware (to avoid having to supply you with a sticky label). That's what this particular app is for.
