Regarding your query, what I would recommend, after you rename the PC, make sure to reboot it.  

After that, I would recommend to run the following script using PowerShell ISE as admin, locally :

Once the script is finished, reboot the device again. In order for the registry keys to be removed / updated, reboot would be needed.  

After this, I would recommend using the CMD installation method instead of .MSI in order to install Atera Agent and assign it to the right customer.
