如何使用命令终止上次打开的Internet Explorer窗口?

IE已经支持自动化,没有必要寻找和终止正确的过程:

Set IE = CreateObject("InternetExplorer.Application")
IE.visible=true
IE.navigate "http://stackoverflow.com/"
while IE.Busy
 WScript.Sleep 555
 wend
IE.Quit

另存为.vbs(并使用父程序/批处理文件中的wscript.exe运行)

使用VBScript

Set objFS=CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
strProcess = objArgs(0) 'argument, which is the process name
strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
' call WMI service Win32_Process 
Set colProcessList = objWMIService.ExecQuery("Select * from Win32_Process Where Name = '"&strProcess&"'")
t=0
For Each objProcess in colProcessList
    ' do some fine tuning on the process creation date to get rid of "." and "+"
    s = Replace( objProcess.CreationDate ,".","")
    s = Replace( objProcess.CreationDate ,"+","")
    ' Find the greatest value of creation date
    If s > t Then
        t=s
        strLatestPid = objProcess.ProcessID
    End If    
Next
WScript.Echo "latest: " & t , strLatestPid
'Call WMI to terminate the process using the found process id above
Set colProcess = objWMIService.ExecQuery("Select * from Win32_Process where ProcessId =" & strLatestPid)
For Each objProcess in colProcess
    objProcess.Terminate()
Next

用途:

c:\test>cscript //nologo kill.vbs "iexplore.exe"
