Function Update-WUModule { <# .SYNOPSIS Invoke Get-WUInstall remotely. .DESCRIPTION Use Invoke-WUInstall to invoke Windows Update install remotly. It Based on TaskScheduler because CreateUpdateDownloader() and CreateUpdateInstaller() methods can't be called from a remote computer - E_ACCESSDENIED. Note: Because we do not have the ability to interact, is recommended use -AcceptAll with WUInstall filters in script block. .PARAMETER ComputerName Specify computer name. .PARAMETER PSWUModulePath Destination of PSWindowsUpdate module. Default is C:\Windows\system32\WindowsPowerShell\v1.0\Modules\PSWindowsUpdate .PARAMETER OnlinePSWUSource Link to online source on TechNet Gallery. .PARAMETER LocalPSWUSource Path to local source on your machine. If you cant use [System.IO.Compression.ZipFile] you must manualy unzip source and set path to it. .PARAMETER CheckOnly Only check current version of PSWindowsUpdate module. Don't update it. .EXAMPLE PS C:\> Update-WUModule .EXAMPLE PS C:\> Update-WUModule -LocalPSWUSource "C:\Windows\system32\WindowsPowerShell\v1.0\Modules\PSWindowsUpdate" -ComputerName PC2,PC3,PC4 .NOTES Author: Michal Gajda Blog : http://commandlinegeeks.com/ .LINK Get-WUInstall #> [CmdletBinding( SupportsShouldProcess=$True, ConfirmImpact="High" )] param ( [Parameter(ValueFromPipeline=$True, ValueFromPipelineByPropertyName=$True)] [String[]]$ComputerName = "localhost", [String]$PSWUModulePath = "C:\Windows\system32\WindowsPowerShell\v1.0\Modules\PSWindowsUpdate", [String]$OnlinePSWUSource = "http://gallery.technet.microsoft.com/2d191bcd-3308-4edd-9de2-88dff796b0bc", [String]$SourceFileName = "PSWindowsUpdate.zip", [String]$LocalPSWUSource, [Switch]$CheckOnly, [Switch]$Debuger ) Begin { If($PSBoundParameters['Debuger']) { $DebugPreference = "Continue" } #End If $PSBoundParameters['Debuger'] $User = [Security.Principal.WindowsIdentity]::GetCurrent() $Role = (New-Object Security.Principal.WindowsPrincipal $user).IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator) if(!$Role) { Write-Warning "To perform some operations you must run an elevated Windows PowerShell console." } #End If !$Role if($LocalPSWUSource -eq "") { Write-Debug "Prepare temp location" $TEMPDentination = [environment]::GetEnvironmentVariable("Temp") #$SourceFileName = $OnlinePSWUSource.Substring($OnlinePSWUSource.LastIndexOf("/")+1) $ZipedSource = Join-Path -Path $TEMPDentination -ChildPath $SourceFileName $TEMPSource = Join-Path -Path $TEMPDentination -ChildPath "PSWindowsUpdate" Try { $WebClient = New-Object System.Net.WebClient $WebSite = $WebClient.DownloadString($OnlinePSWUSource) $WebSite -match "/file/41459/\d*/PSWindowsUpdate.zip" | Out-Null $OnlinePSWUSourceFile = $OnlinePSWUSource + $matches[0] Write-Debug "Download latest PSWindowsUpdate module from website: $OnlinePSWUSourceFile" #Start-BitsTransfer -Source $OnlinePSWUSource -Destination $TEMPDentination $WebClient.DownloadFile($OnlinePSWUSourceFile,$ZipedSource) } #End Try catch { Write-Error "Can't download the latest PSWindowsUpdate module from website: $OnlinePSWUSourceFile" -ErrorAction Stop } #End Catch Try { if(Test-Path $TEMPSource) { Write-Debug "Cleanup old PSWindowsUpdate source" Remove-Item -Path $TEMPSource -Force -Recurse } #End If Test-Path $TEMPSource Write-Debug "Unzip the latest PSWindowsUpdate module" [Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem") | Out-Null [System.IO.Compression.ZipFile]::ExtractToDirectory($ZipedSource,$TEMPDentination) $LocalPSWUSource = Join-Path -Path $TEMPDentination -ChildPath "PSWindowsUpdate" } #End Try catch { Write-Error "Can't unzip the latest PSWindowsUpdate module" -ErrorAction Stop } #End Catch Write-Debug "Unblock the latest PSWindowsUpdate module" Get-ChildItem -Path $LocalPSWUSource | Unblock-File } #End If $LocalPSWUSource -eq "" $ManifestPath = Join-Path -Path $LocalPSWUSource -ChildPath "PSWindowsUpdate.psd1" $TheLatestVersion = (Test-ModuleManifest -Path $ManifestPath).Version Write-Verbose "The latest version of PSWindowsUpdate module is $TheLatestVersion" } Process { ForEach($Computer in $ComputerName) { if($Computer -eq [environment]::GetEnvironmentVariable("COMPUTERNAME") -or $Computer -eq ".") { $Computer = "localhost" } #End If $Computer -eq [environment]::GetEnvironmentVariable("COMPUTERNAME") -or $Computer -eq "." if($Computer -eq "localhost") { $ModuleTest = Get-Module -ListAvailable -Name PSWindowsUpdate } #End if $Computer -eq "localhost" else { if(Test-Connection $Computer -Quiet) { Write-Debug "Check if PSWindowsUpdate module exist on $Computer" Try { $ModuleTest = Invoke-Command -ComputerName $Computer -ScriptBlock {Get-Module -ListAvailable -Name PSWindowsUpdate} -ErrorAction Stop } #End Try Catch { Write-Warning "Can't access to machine $Computer.
