:: Developed as an alternative over the manual computer naming of XXXXXX[service tag]
::
:: This batch file will rename the computer using the servivce tag in BIOS.

:: find out what path the batch file is in
:: set batch_path=%~dp0

:: change drive
:: %batch_path:~0,2%

:: crop the last character and cd into it
:: cd %batch_path:~0,-1%

:: clear screen show bitlocker status
:: cls

:: WMIC computersystem where caption=’current_pc_name’ rename new_pc_name

:: pipe machine service tag to serial.txt so that later we can reverse pipe into the variable that used to name the capture file
wmic bios get serialnumber | find /v “SerialNumber” > %temp%/serial.txt

::pipe in serial
set /p serial=<%temp%\serial.txt

:: trim spaces
set serial_temp=%serial: =%

:: store serial
set serial=%serial_temp%

set current_name=%hostname%
