改成这样会快些吧：

@echo off
setlocal enabledelayedexpansion
set num=0
set str=abcdefghijklmnopqrstuvwxyz
:start
if %num%==10000 goto :eof
set /a a=%random%%%26
set /a b=%random%%%10
set /a c=%random%%%26
set /a d=%random%%%10
set /a e=%random%%%26
echo !str:~%a%,1!%b%!str:~%c%,1!%d%!str:~%e%,1!.163.COM>>ID.txt
set /a num+=1
goto :start
