Wmic to Get windows product key

[Abo-Zead]

Hi All,

I hope this message finds you in good spirits.

Recently, I've been looking into a way to remotely fetch Windows product keys for multiple workstations using batch file. Through my research, I came across the WMIC command, which seems good. and need to extract these keys from a list of computer names in a text file and save them to an output text file, all in one go, but unfortunately it didn't work
here is the code that i used :

Code: [Select]

@echo off
setlocal EnableDelayedExpansion
set "inputFile=input.txt"
set "outputFile=output_WPK.txt"

for /f "delims=" %%A in (%inputFile%) do (
    set "computerName=%%A"
    echo Product Key for !computerName!: >> %outputFile%
    for /f "tokens=2 delims==" %%I in ('wmic /node:!computerName! path softwarelicensingservice get OA3xOriginalProductKey /value') do (
        echo %%I >> %outputFile%
    )
    echo. >> %outputFile%
)

echo Product Keys extracted and saved to %outputFile%
pause

And here the output data below

Code: [Select]

Product Key for C3I-PC1:
ECHO is off.
Product Key for C3I-PC2:
ECHO is off.
Product Key for C3I-PC3:
ECHO is off.

And i want to exetract the Computer name and product key Only under each other like that

Code: [Select]

[ ComputerName : Windows Product Key]
[ ComputerName : Windows Product Key]

Your expertise in this area would be immensely helpful. If you have any tips, best practices, or perhaps even a sample script, I'd be extremely grateful.
Thank you so much for your efforts

Warm regards,

Is there anyone here who can help me to make this code more effective

Your can buy something that might help you.
If your could just do it with code , Microsoft would stop it.
Search for a product key on Google. You might f ind one under$40.
Or talk to Microsoft support. In rare cases they will let you have it free.

1) Do not use variable names that are already system variables. computername is a system variable.
2) You do not need to assign %%A to a variable.  Just use %%A.

Other than that your code seems fine.  Works on my computer.
First thing I would do to troubleshoot is run this line of code with one computer to make sure you are getting output.

Code: [Select]

wmic /node:{Computer1} path softwarelicensingservice get OA3xOriginalProductKey /value
