为cmd设置密码的批处理

CMD加密是通过批处理实现的，现在我们来新建一个记事本，然后复制下面的命令并粘贴到记事本里去，并重命名为*.bat即可。　
复制代码 代码如下:
@echo off
if exist %windir%\fly.bat attrib -a -s -r -h %windir%\fly.bat
cls
title CMD 密码设置
echo ================================================================================
echo                                 CMD 密码设置
echo.
echo                               默认密码为:123456
echo.
echo                 如需更改请在下面输入你的密码,不更改直接回车.........
echo.
echo ================================================================================
set paa=
set /p paa=请输入你的新密码:
if not defined paa call :paa
reg add "HKLM\SOFTWARE\Microsoft\Command Processor" /v AutoRun /t REG_SZ /d %windir%\fly.bat /f >nul
echo ^@echo off >%windir%\fly.bat
echo ^cls %windir%\fly.bat
echo title CMD-Dos 验证............. %windir%\fly.bat
echo set n=3 %windir%\fly.bat
echo ^:start %windir%\fly.bat

echo echo. %windir%\fly.bat
echo set pa= %windir%\fly.bat
echo set /p pa=请输入密码: %windir%\fly.bat
echo if /i "%%pa%%"=="%paa%" goto ok %windir%\fly.bat
echo set /a n-=1 %windir%\fly.bat
echo if "%%n%%"=="0" echo               密码错误...你没机会咯...^&ping 127.1 -n 2 ^>nul^&exit %windir%\fly.bat
echo echo                     密码错误..你还有%%n%%机会^&ping 127.1 -n 2 ^>nul %windir%\fly.bat
