SET CHARS=abcdefghijklmnopqrstuvwxyz0123456789
SET /A CHAR_LENGTH=26+10
SET /A ALPHA_LENGTH=14
SET HOSTNAME=W

SET LINE=
FOR /L %%a in (1 1 %ALPHA_LENGTH%) do (
    SET /A CHAR_INDEX=!random! %% %CHAR_LENGTH%
    CALL SET EXTRACTED_CHAR=%%CHARS:~!CHAR_INDEX!,1%%
    SET LINE=!LINE!!EXTRACTED_CHAR!
)

SET HOSTNAME=%HOSTNAME%%LINE%

reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ComputerName\ActiveComputerName" /v ComputerName /t reg_sz /d %HOSTNAME% /f
reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ComputerName\ComputerName" /v ComputerName /t reg_sz /d %HOSTNAME% /f
