How to uninstall the Atera agent by Powershell Script <\/p>\n\n\n\n

Regarding your query, what I would recommend, after you rename the PC, make sure to reboot it.\u202f <\/p>\n\n\n\n

After that, I would recommend to run the following script using PowerShell ISE as admin, locally :\u202f <\/p>\n\n\n\n

Once the script is finished, reboot the device again. In order for the registry keys to be removed \/ updated, reboot would be needed.\u202f <\/p>\n\n\n\n

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. <\/p>\n\n\n\n
