Excel VBA to read registry key RRS feed

  • Question

  • I use Excel to perform various queries against a list of servers and drop the results in the adjacent columns (i.e. ping, OS version, Uptimes, etc). All works fine doing WMI calls etc. I am trying to read a registry key now so that I can populate the cell with the value of a specific key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Download\LastSuccessTime ) so I can see the last time Windows Update ran successfully. It works fine as a stand-alone vbs. In excel I am having the issue. I obviously had to modify it a little from the original VBS but here is what I have:

    Function WinUpdate(Host)
    Dim oReg As Object
    Dim strKeyPath As String
    Dim strValueName As String
    Dim strvalue
    Const HKEY_LOCAL_MACHINE = &H80000002
       strComputer = Host
     Set oReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")
    strKeyPath = "SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Download"
    strValueName = "LastSuccessTime"
    oReg.GetStringValue HKEY_LOCAL_MACHINE, strKeyPath, strValueName, strValue
    WinUpdate = strValue
    End Function
    Sub GetWinUpdate()
      Dim Cell As Range
      Dim ipRng As Range
      Dim Result As String
      Dim Wks As Worksheet
    Set Wks = Worksheets("Sheet1")
    Set ipRng = Wks.Range("A2")
    Set RngEnd = Wks.Cells(Rows.Count, ipRng.Column).End(xlUp)
    Set ipRng = IIf(RngEnd.Row < ipRng.Row, ipRng, Wks.Range(ipRng, RngEnd))
      For Each Cell In ipRng
        Result3 = WinUpdate(Cell)
        Cell.Offset(0, 4) = Result3
      Next Cell
    End Sub
    (Don't mind all the ipRng references - part of my other tests)

    strValue is never populated.  In all my troubleshooting I created a reg key as a test and I am pretty sure it worked.  What I found as the only difference and pinpointed the problem to be the space in the path of what i am looking for.  Now of course I can not get anything to work (with or without a space).  So I'm either crazy and never got it working or i've been staring at this too long!

    Any help would be greatly appreciated

    It's recommended to download and install Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office programs.
