Hi, I removed all devices from my Microsoft account and now I want to register my gaming PC back. However, it’s displaying no serial number. I used Powershell with the command: Get-WmiObject Win32_BIOS | Select-Object SerialNumber. It was showing the System Serial Number instead. I tried changing the product key, but that didn’t help. Windows recently updated to 25H2. The notebook is working normally, but the PC isn’t showing up. Do I need to reinstall the PC or is there a solution?

As discussed with @cruisetung and @Dubkiss, you should reach out to Microsoft for help. Any more support regarding the serial number or product key issue may breach forum guidelines. This thread will be closed to prevent additional comments.

Use the command prompt to retrieve OA3xOriginalProductKey
or run PowerShell with the query to get it.

At line 1 character 62, there was an unexpected token.
The parser encountered a closing parenthesis where it wasn't properly closed.

Reading back: Check if you're looking for the Product key. For the Product key, paste the following script:
function Get-WindowsKey {
$key = (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
return $key}
ProductKey = Get-WindowsKeyWrite-Output "Your Windows Product Key is: $ProductKey"
