You don't. Installing the new key removes the previous one.

You can uninstall previous product key, but if it was generic which cannot activate OS, this operation is excessive. New working key will replace the old key, even though it may remain as a line in Registry for historical purpose. Uninstallation of current key has a sense when you want to transfer the activation from one your machine to another one (if the licence allows it), and hand the old machine to other user who should acquire another key for this OS. Otherwise uninstallation of the key can be skipped.

Using Jelly Bean Keyfinder I get this result
..............................
Windows 10 Enterprise
Product Part No.: [TH]X19-9
Installed from 'Full Packaged Product' media.
Product ID: xxxxxxxxxxxxxx match to CD Key data

CD Key: xxxxxxxxxxxxxxxxxx
