Once I had some difficulty changing Serial # of one of my ProSticks. I used the Windows software “RTLTool” with success. Use it carefully, see note below.
Go to

Scroll down to “The Files”, under which you will find “hosted on Google Drive Link” where the files are hosted. One of the files on Google Drive is “RTLTool”. Download it.
This software is portable i.e. does not require installation, and runs directly when RTLTool.exe is double-clicked.
IMPORTANT NOTE:
This tool can modify many parameters. Take care while using it that you do NOT modify anything other than the Serial Number. Modifying other parameters, without fully understanding what are you doing, may result in bricking your Dongle.
