Find your key from inside Windows (windows 10 找序號的方法)

Find your key from inside Windows

Windows 找序號方法：

以系統管理員身分執行 命令提示字元(command prompt(CMD))或PowerShell

Entering the following lines into an admin Command Prompt or PowerShell worked to display the OEM key embedded in our system's UEFI/BIOS. However, these commands didn't return any keys on other two machines we used for testing despite Windows 10 being activated.

 輸入下面指令可得到Windows 10的序號：

wmic path softwarelicensingservice get OA3xOriginalProductKey

or (或使用PowerShell輸入下面指令：)

powershell "(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey"
