这篇文章主要介绍了查询电脑开关机时间的vbs代码,需要的朋友可以参考下
核心代码：

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
Set colLoggedEvents = objWMIService.ExecQuery _
("Select * from Win32_NTLogEvent " _
& "Where Logfile = 'System' And EventCode = '6005' Or EventCode = '6006'")
For Each objEvent In colLoggedEvents
  Flag = Flag + 1
  If Flag = 1 Then
    Wscript.Echo "本次开机时间: " & FormatWMIUTC(objEvent.TimeWritten)
  ElseIf Flag = 2 Then
    Wscript.Echo "上次关机时间: " & FormatWMIUTC(objEvent.TimeWritten)
  ElseIf Flag = 3 Then
    Wscript.Echo "上次开机时间: " & FormatWMIUTC(objEvent.TimeWritten)
    Exit For
  End If
Next
 
'FormatUTC
Function FormatWMIUTC(WMIDateString)
  DS = " // :: "
  FormatWMIUTC = Left(WMIDateString,2)
  For i = 2 To 7
    FormatWMIUTC = FormatWMIUTC & Mid(WMIDateString, i * 2 - 1, 2) & Mid(DS,i,1)
  Next
  'FormatWMIUTC = Mid(WMIDateString, 1, 4) & "年" _
  '      & Mid(WMIDateString, 5, 2) & "月" _
  '      & Mid(WMIDateString, 7, 2) & "日 " _
  '      & Mid (WMIDateString, 9, 2) & ":" _
  '      & Mid(WMIDateString, 11, 2) & ":" _
  '      & Mid(WMIDateString,13, 2)
End Function

将上面的代码保存为vbs后缀的文件，双击运行即可。看到这次的开机时间，上次的开关机时间
