Hi,

Get-HotFix : A positional parameter cannot be found that accepts argument 'kb4562030.msu'.

  • CategoryInfo : InvalidArgument: (:) [Get-HotFix], ParameterBindingException

PowerShell Script:

$UpdatePath = "C:\Updates"

ForEach ($update in $Updates)
{
$UpdateFilePath = $update.FullName
if (Get-Hotfix -Id -eq $update) {
Write-Host " Windows Update Already Installed on Computer "
}
else
{
write-host "Installing Update on Computer $update"
Start-Process -wait wusa -ArgumentList "/update $UpdateFilePath","/quiet","/norestart"

    I haven't run this code but I think it should do what you're trying to accomplish:

    $UpdatePath = "C:\Updates"
    Get-HotFix > "$UpdatePath\Old_HotFix_List.txt"  
    $installed = (Get-HotFix).HotFixID
    Get-ChildItem -Path $UpdatePath -Include *.msu | 
        ForEach-Object{
            if ($_.Name -match "^.+-(kb[^-]+)-"){   # name looks like "windows10.0-kb5003537-x86-ndp48_0f7a496cc7e0dc08f0494e8c9e3c6a83a9175e97.msu"
                $kbid = $matches[1]
                if ($installed -contains $kbid)
                {
                    Write-Host "Windows Update '$kbid' Already Installed on Computer "
                }
                else{
                    $UpdateFilePath = $_.FullName
                    write-host "Installing Update '$kbid' on Computer $update"
                    Start-Process -wait wusa -ArgumentList "/update $UpdateFilePath","/quiet","/norestart"
                }
            }
            else{
                Write-Host "Did not find KB number in the filename '$_'"
            }
        }
    Get-HotFix > "$UpdatePath\New_HotFix_List.txt"
    timeout 5
    shutdown /r
    

    Note that the variable "$update" (which should hold the name of the computer on which to run "wsua") is undefined. You should also check that "wsua" is sufficient to start the process.

    Hi Rich,

    now its working, but still have 01 issue as the if condition "Line No: 6 & 8" not working, the installation process starts didn't prompt any massage as mentioned in script if the update is already installed.
