Copy Mac Address into Clipboard help in Windows 7

Question

Given the batch script below. How would I be able to give me a MAC address with no dashes and add a "D" in front of it? So when I go and paste, it has a MAC address that starts with a D and there are no dashes? Possibly even using what I copied to automatically change the computer name with it using newsid?

@ECHO OFF

FOR /f "tokens=12 delims= " %%a IN ('IPCONFIG /all^|FINDSTR "Physical Address"') DO (
    SET PA=%%a
    IF NOT "%PA%"=="." GOTO Done
)

:Done

ECHO %PA%| CLIP
CLS
ECHO The Physical Address has been copied to the clipboard.
ECHO.
PAUSE
EXIT

Answer 1

Use echo D%PA:-=%|clip instead.

Note though, that you're getting the last MAC address on your computer which could really be anything. At least on my machine that doesn't correspond to any phsyical interface.
