　　合理运用注册表能解决一些系统运用方面的问题，下面列举些我常用的注册表设置。将文本用记事本程序存为.reg后缀的文件后双击即可。

改变命令行颜色
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"CompletionChar"=dword:00000009
"DefaultColor"=dword:0000004e
"EnableExtensions"=dword:00000001

取消隐藏系统文件（中毒后无法更改设置时使用）
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\NOHIDDEN]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="@shell32.dll,-30501"
"Type"="radio"
"CheckedValue"=dword:00000002
"ValueName"="Hidden"
"DefaultValue"=dword:00000002
"HKeyRoot"=dword:80000001
"HelpID"="shell.hlp#51104"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="@shell32.dll,-30500"
"Type"="radio"
"CheckedValue"=dword:00000001
"ValueName"="Hidden"
"DefaultValue"=dword:00000002
"HKeyRoot"=dword:80000001
"HelpID"="shell.hlp#51105"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\SuperHidden]
"Type"="checkbox" 
"Text"="@shell32.dll,-30508"
"WarningIfNotDefault"="@shell32.dll,-28964"
"HKeyRoot"=dword:80000001
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"ValueName"="ShowSuperHidden"
"CheckedValue"=dword:00000000
"UncheckedValue"=dword:00000001
"DefaultValue"=dword:00000000
"HelpID"="shell.hlp#51103"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\SuperHidden\Policy]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\SuperHidden\DontShowSuperHidden]@=""

在鼠标右键添加用UE和用记事本打开
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell]
@="open"
[HKEY_CLASSES_ROOT\*\shell\UltraEdit-32]
[HKEY_CLASSES_ROOT\*\shell\UltraEdit-32\command]
@="f:\\Program Files\\UltraEdit-32\\uedit32.exe  \"%1\""
[HKEY_CLASSES_ROOT\*\shell\用记事本打开]
[HKEY_CLASSES_ROOT\*\shell\用记事本打开\command]
@="notepad.exe \"%1\""

顺便加个批处理

重建桌面右下角的图标
reg delete "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TrayNotify"  
/v "IconStreams" /f
ntsd -c q -pn explorer.exe
