Hi 梓珺 张,
This information is stored in the registry under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation
You can import the support information by creating String Values like this (copy the code below in a text editor, replace the values and save is as .reg for easy install):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation]
"SupportURL"="http://www.TheCoolPCCompany.com"
"Manufacturer"="The Cool PC Company"
"SupportPhone"="+1 000 000 000"
"SupportHours"="9AM - 6PM"
"Model"="Copilot+ PC"
The 'Model' will display on top of the about screen just under the device name, rest of the info will show under support
Hope this helps,
