Add column to an output

Hi,

For a single additional column, you can just cram it into the Select-Object as shown below.

If you were going to work with multiple new or existing columns, you'd probably branch out into a dedicated hash table.

Invoke-Command -ComputerName $server -ScriptBlock {
    # Get the last boot time. Getting it here up front once rather than many times within the loop is more efficient.
    $LastBootTime = (Get-CimInstance -ClassName Win32_OperatingSystem).LastBootUpTime;

    # Same principle for the cutoff date. No reason to have this in the loop.
    $CutoffDate = [datetime]::Today.AddDays(-10);

    # Loopy-da-loop time.
    Get-HotFix |
        Where-Object { $_.InstalledOn -gt $CutoffDate; } |
            Select-Object -Property @{name="LastBootUpTime"; expression={ $LastBootTime }}, CSName, Description, HotFixID, InstalledBy, InstalledOn;
}

Which gives you:

Note that the real variable name for Source is CSName. You can re-brand that if you like back to Source using the same approach as for the new LastBootUpTime column but I haven't bothered doing so in this example.

Cheers,
