Look up information for multiple CLSIDs; pipeline input is a work-in-progress

Lookup CLSID in PowerShell

Function Get-Clsid {
    [CmdletBinding()]
    param (
    [Parameter (Mandatory=$true,Position=0,ValueFromPipeline=$true)]
    [Array]$CLSID
    )

    $CLSID_KEY = "HKLM:\SOFTWARE\Classes\CLSID"
    $ErrorActionPreference = 'SilentlyContinue'

    ForEach ($C in $CLSID) {
        If (($C -like "{*}") -or ($C -notlike "*`-*`-*`-*`-*")) {
            $Path = "$CLSID_KEY\$C"
        } Else {
            $Path = "$CLSID_KEY\`{$C`}"
        }
        If (Test-Path $Path) {
            $Name = (Get-ItemProperty -Path $Path).'(default)'
            $DLL = (Get-ItemProperty -Path "$Path\InProcServer32").'(default)'
            If ($null -eq $Name) {
                $Name = "Class name not found."
            }
            If ($null -eq $DLL) {
                $DLL = "DLL info not found."
            }
            $C,$Name,$DLL,''
        } Else {
            "No results found for query: $C`r`n"
        }
    }
}

Summary of changes from the original Gist:
• Renamed to use one of the "approved" verbs, "get"
• Script now allows for multiple CLSIDs
• For typical CLSIDs, script will search both with and without brackets '{}'
• Allows for the existence of atypical values within the CLSID key
• Attempts to account for $false/$null results

ToDo:
• ValueFromPipeline currently only returns results from the last item in the array under some circumstances
• May change line 12 to use regex
