1. 怎么程序都变成了记事本

Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOTexefile] @="应用程序""EditFlags"=hex:38,07,00,00"TileInfo"="prop:FileDescription;Company;FileVersion""InfoTip"="prop:FileDescription;Company;FileVersion;Create;Size" [HKEY_CLASSES_ROOTexefileDefaultIcon] @="%1" [HKEY_CLASSES_ROOTexefileshell] [HKEY_CLASSES_ROOTexefileshellopen]"EditFlags"=hex:00,00,00,00 [HKEY_CLASSES_ROOTexefileshellopencommand] @=""%1" %*" [HKEY_CLASSES_ROOTexefileshellrunas] [HKEY_CLASSES_ROOTexefileshellrunascommand] @=""%1" %*" [HKEY_CLASSES_ROOTexefileshellex] [HKEY_CLASSES_ROOTexefileshellexDropHandler] @="{86C86720-42A0-1069-A2E8-08002B30309D}" [HKEY_CLASSES_ROOTexefileshellexPropertySheetHandlers] [HKEY_CLASSES_ROOTexefileshellexPropertySheetHandlersPifProps] @="{86F19A00-42A0-1069-A2E9-08002B30309D}" [HKEY_CLASSES_ROOTexefileshellexPropertySheetHandlersShimLayer Property Page] @="{513D916F-2A8E-4F51-AEAB-0CBC76FB1AF8}" [HKEY_CLASSES_ROOTexefileshellexPropertySheetHandlers{B41DB860-8EE4-11D2-9906-E49FADC173CA}] @="" [HKEY_LOCAL_MACHINESOFTWAREClasses.exe] @="exefile""Content Type"="application/x-msdownload" [HKEY_LOCAL_MACHINESOFTWAREClasses.exePersistentHandler] @="{098f2470-bae0-11cd-b579-08002b30bfeb}" [HKEY_LOCAL_MACHINESOFTWAREClassesexefile] @="应用程序""EditFlags"=hex:38,07,00,00"TileInfo"="prop:FileDescription;Company;FileVersion""InfoTip"="prop:FileDescription;Company;FileVersion;Create;Size" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileDefaultIcon] @="%1" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshell] [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellopen]"EditFlags"=hex:00,00,00,00 [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellopencommand] @=""%1" %*" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellrunas] [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellrunascommand] @=""%1" %*" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellex] [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellexDropHandler] @="{86C86720-42A0-1069-A2E8-08002B30309D}" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellexPropertySheetHandlers] [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellexPropertySheetHandlersPifProps] @="{86F19A00-42A0-1069-A2E9-08002B30309D}" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellexPropertySheetHandlersShimLayer Property Page] @="{513D916F-2A8E-4F51-AEAB-0CBC76FB1AF8}" [HKEY_LOCAL_MACHINESOFTWAREClassesexefileshellexPropertySheetHandlers{B41DB860-8EE4-11D2-9906-E49FADC173CA}] @="" 把上面的粘帖复制到记事本，然后另存为***.reg，双击导入确定即可。

2. 我不小把可应用程序的打开方式变成了记事本

新建个记事本文件，输入 ================================ Set wso = CreateObject("Wscript.Shell") gwrite "HKEY_CLASSES_ROOTexefileshellopencommand","%1 %*" msgbox"修复成功！" =============================== 另存为123.vbs 要把扩展名.txt改掉，执行即可 或者新建个记事本文件，输入 REGEDIT4 ；功能：恢复EXE文件打开方式，马上生效 [HKEY_CLASSES_ROOTexefileshellopencommand] @=""%1" %*" 保存，退出后把名字改成 g，主要是把扩展名.txt改成.reg。

执行即可。

3. 应用程序变成了记事本文件怎么还原

新建文本文档，复制以下代码，保存，把.txt改为.bat。运行，然后输入你要还原的文件类型就行了。==========================

@echo off

setlocal enabledelayedexpansion

set /p "v=请输入扩展名（如txt），或者直接回车撤销所有打开方式选择： "

set "v=.!v:.=!"

if "!v!"=="" (

reg delete "HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts" /f

reg delete "HKCUSoftwareClasses" /f

) else (

reg delete "HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts!v!" /f

reg delete "HKCUSoftwareClasses!v!" /f

reg delete "HKCUSoftwareClasses!v:.=!_auto_file" /f

)

taskkill /im explorer.exe /f

start %windir%explorer.exe

pause

goto :eof

复制粘贴的，我刚才就这样搞定的！！！O（∩_∩）O哈哈~
