When I searched it said that they should be stored in the Registry.
I cannot find them in there.
How else can I reset the input controls please?
Adding a new user account each time is a pita 
Use PlayerPrefs.DeleteKey.

Do you mean that I have to add that somewhere to my project?
Could you just tell me where the pref files is on the PC please, as I would rather do it that way.
Yes, just make a reset preferences function. Many games do this.
There are no files, they’re in the registry somewhere. (I don’t know anything more specific than that since I don’t use Windows.)
