I solved the issue of Win10 freezing when I chose "Change Product Key"...here's how:
--Open Settings and in the Search bar type "UAC"...open the resulting "User Account Control Settings"
--Change the UAC settings to "Always Notify" (you can change this back when we're finished)
--Go back to the "Change Product Key" button....viola! Win10 UAC prompts you about making changes, but the proper Change Product Key pane is displayed
This worked for me; I toggled my UAC settings back to custom when finished :)
