PSWindowsUpdate File Not Found Exception


I recently updated PSWindowsUpdate from version to the latest version ( and when I try to run the script:

Write-Host "      Centralized Update"
Write-Host "================================"

ipmo activedirectory
$computers = Get-ADComputer -Filter {enabled -eq $true} -properties * -SearchBase "OU=Workstations, DC=contoso, DC=com" | select name
$Script = {ipmo PSWindowsUpdate; Get-WUInstall -AcceptAll -Install -Verbose}

foreach ($computer in $computers) {
  Write-Host "Running update on:" $
  Invoke-WUJob -ComputerName $ -Script $Script -Confirm:$false -RunNow

Write-Host "================================"

I get the following error:

Invoke-WUJob : The system cannot find the file specified. (Exception from HRESULT: 0x80070002) At C:\Users\Administrator\Desktop\Update_Workstations.ps1:10 char:2 + Invoke-WUJob -ComputerName $ -Script $Script -Confir ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Invoke-WUJob], FileNotFoundException + FullyQualifiedErrorId : System.IO.FileNotFoundException,PSWindowsUpdate.InvokeWUJob

The only edit to the script was to change:

Invoke-WUInstall -ComputerName $ -Script $Script -Confirm:$false


Invoke-WUJob -ComputerName $ -Script $Script -Confirm:$false -RunNow

More details:

  • The version of PowerShell is 5.1 (both client and server side)
  • The list of terminals is correctly extracted from the "Workstations" organizational unit
  • I can connect via "enter-pssession" to all the terminals without problems
  • Using "Invoke-Command" instead of "Invoke-WUJob" run but fails at the time of download with the error "UnauthorizedAccessException"

What's wrong with the code ? before updating to version it works fine
