How I can execute extern Module Commands on a remote Computer in Powershell without install the Module?

Question

I want to execute powershell commands on a remote computer and I use a extern Module on the localhost. I tested it and get the message that I don't can use the command on the remote computer but locally it works.

So I have installed the module on the remote computer via Import-Module and it works.

But this is bad and I want not install the module on every computer in the company.

Here is my PS Script:

$cred = Get-Credential

$isConnect = Test-WSMan edv-004

if($isConnect){

    #Get-WUHistory is from a extern Module and list the Updatehistory of a computer
    Invoke-Command -ComputerName edv-004 -ScriptBlock { Get-WUHistory } -Credential $cred

    Write-Host "Skript wurde auf ausgeführt..."
}

Before I run this script I have do this:

Enable-PSRemoting -Force
Set-Item WSMan:\localhost\Client\TrustedHosts * -Force  #for testing 
Restart-Service WinRM

So how I can execute extern module commands without install it on the remote computer? :/

Answer 1

You can import a module from a shared location (if your execution policy allows it):

Invoke-Command -ComputerName edv-004 -ScriptBlock {
  Import-Module \\server\share\YourModule
  Get-WUHistory
} -Credential $cred

but you can't run a function from a module without importing the module first.
