Batch Script to obtain the OEM License key on a Windows computer
None really, I made this script in my spare time
This script retrieves the OEM Product Key from a computer, OEM Keys are those used on devices sold by manufactuers (example: Dell, Asus, HP, Lenovo, etc.), these keys are usually stored in the UEFI, and will always reactivate the computer in the event you need to reinstall windows, however they cannot be transferred, and they die when the computer dies.
As per what the script is doing to retrieve it, it uses WMIC and VBScript, WMIC to retrieve the key and VBScript to create the text box to display the key
This is the WMIC Command normally used to retireve the key wmic path softwarelicensingservice get OA3xOriginalProductKey /value
And this command creates the VBScript to show it set "vbscript=%temp%\popup.vbs" echo msgbox "%message%",0,"OEM Windows Key" > %vbscript% cscript /nologo %vbscript% del %vbscript%
No, that is not the intention of this script, it simply exists to show the key stored in the UEFI, it does not have any capability to send data. Don't believe me? This is what VirusTotal code insights says
"The code snippet is a batch script that retrieves the OEM Windows key from the system and displays it in an input box. It uses the wmic command to get the key and then checks if the key is empty or contains only spaces. If the key is valid, it displays the key in an input box using a VBScript script. Finally, it cleans up and exits.
The code does not contain any obfuscated code or remote file downloads. It does not pose any security risks or recommendations."
Additonally you can always look at the code if you're THAT paranoid.
No, this command does not work with retail keys since they aren't stored in the UEFI, these keys also don't die, as they can be transferred.
