Can not set a serial number to my VM Windows 10 ARM

Hi,
I try to set a serial number to my VM Windows 10 ARM but it does not seem to works.
I tried to add the parameter devices.smbios.serial="12345678" in boot indicators of my VM or directly modify the section serialnumber in file config.pvs

But in my VM Windows 10 when I execute the command : wmic bios get serialnumber
The serial number displayed is always Parallels-XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX

Any ideas ?
FYI : Actually use Parallels Desktop Pro 16.5 evaluation

 

Hi, please check this link and let us know if it's not that case.

 

I don't think so.
My Windows 10 Pro ARM is activated and my processor is seen as an Apple Silicon in Windows

 

I am having the same issue.
Extracting the Hardware ID for Windows Autopilot is based on the serial number and it does not work. Instead, the resulting serial is Parallels-XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX.
