Windows Update reporting RRS feed

  • Question

  • Good day,

    I have a script I found that I would like to use that creates a CSV file for Windows update status of PC's in a txt file. The script below works exactly how I want the report to show, but I don't want to have to run it manually on each PC. I was playing with using a 'foreach' statement that would call out each PC in the list shown at the end. Any help is appreciated for this PS Noob. 

    #Script name WuaHistory.ps1
    #Convert Wua History ResultCode to a Name # 0, and 5 are not used for history # See https://msdn.microsoft.com/en-us/library/windows/desktop/aa387095(v=vs.85).aspx
    function Convert-WuaResultCodeToName
    param( [Parameter(Mandatory=$true)]
    [int] $ResultCode
    $Result = $ResultCode
    $Result = "Succeeded"
    $Result = "Succeeded With Errors"
    $Result = "Failed"
    return $Result
    function Get-WuaHistory
    #Get a WUA Session
    $session = (New-Object -ComObject 'Microsoft.Update.Session')
    #Query the latest 1000 History starting with the first recordp
    $history = $session.QueryHistory("",0,50) | ForEach-Object {
    $Result = Convert-WuaResultCodeToName -ResultCode $_.ResultCode
    #Make the properties hidden in com properties visible.
    $_ | Add-Member -MemberType NoteProperty -Value $Result -Name Result
    $Product = $_.Categories | Where-Object {$_.Type -eq 'Product'} | Select-Object -First 1 -ExpandProperty Name
    $_ | Add-Member -MemberType NoteProperty -Value $_.UpdateIdentity.UpdateId -Name UpdateId
    $_ | Add-Member -MemberType NoteProperty -Value $_.UpdateIdentity.RevisionNumber -Name RevisionNumber
    $_ | Add-Member -MemberType NoteProperty -Value $Product -Name Product -PassThru
    Write-Output $_
    #Remove null records and only return the fields we want
    $history |
    Where-Object {![String]::IsNullOrWhiteSpace($_.title)} |
    Select-Object Result, Date, Title, SupportUrl, Product, UpdateId, RevisionNumber
    #Get all the update History, formatted as a table
    Get-WuaHistory | Export-Csv -Path .\WuaData.csv -NoTypeInformation

    I was playing with the idea below and using the 'foreach' statement, but am unable to get it to work.

    #Invoke Credentials
    $cred = get-credential 
    #Pull list of computers
    $Computers = get-content -Path ".\list.txt" 
    ForEach ($Computer in $Computers)
    Invoke-Command -ComputerName $Computer -filepath ".\WuaHistory.ps1" -credential $cred 

    Thank you

  • You can download the WU module from the PowerShellGallery and it will have to code needed to do what you ask.

    Install-Module  PSWindowsUpdate

  • Also if you are on Windows 10 the module and commands are already provided:

    Get-Command -Module WindowsUpdateProvider

    The commands that can be remoted accept a computer name.  Most WU commands cannot be remoted even with Invoke.
