一、新建一个TXT文本文档，将以下内容复制进去，保存为SuperHidden.vbs，放入C:\Windows目录下
Dim WSHShell
Set WSHShell = WScript.CreateObject("WScript.Shell")
sTitle1 = "SSH=0"
sTitle2 = "SSH=1"

if WshSHell.RegRead("HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt") = 0 then

WshSHell.RegWrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt", "1", "REG_DWORD"

WshSHell.SendKeys "{F5}+{F10}e"
else

WshSHell.RegWrite "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt", "0", "REG_DWORD"

WshSHell.SendKeys "{F5}+{F10}e"
end if

Set WSHShell = Nothing
WScript.Quit(0)
怎么显示文件的扩展名二、再将以下内容复制到TXT，保存为文件，运行即可
Windows Registry Editor Version 5.00
