Hello,
Do you want to change the publisher name?
The publisher specified in the subject field of the signing certificate used to sign the package. This is a string that contains a comma-delimited X.500 distinguished name.
If you want to change it, you should change the certificate. Also you can create a test certificate with another name.
Double click Package.appxmanifest->Packaging->Publisher->Choose Certificate
In this dialog you can choose Certificate from file or create a test Certificate.

Best regards,
