PowerShell Orphan share remover Tool (Update)



I needed to clean some Orphan Shares on our servers,
but when I did lookup the MSH script, I make last year I found that the stats did not work anymore in PowerShell, also it had a boolean parameter, since we have a Switch argument now in PowerShell that would be better,

So I Updated the MSH Orphan share remover Tool To PowerShell,
I changed the $doChange Bool to a [Switch], (new in powerShell RC1
see PowerShell AD site Finder) also the -eq behavour when checking an array changed,
so I needed to change the to -contains (for the example I did leave them in but I switched also to keeping count in the script)

The Update script looks like this :

# OrphanShares.PS1
# Checks / Removes Orphan Shares
# /\/\o\/\/ 2005
# V2 updated to PowerShell RC1

param (
  [string] $Computer = ".",   
  [Switch] $Remove
)

# Connect to registry

$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $Computer)
$key = $Reg.OpenSubKey("SYSTEM\CurrentControlSet\Services\LanmanServer\Shares", $True)

# get shares in Registry :

$Regshares = $Key.GetValueNames()

# get Existing shares :

$shares = @();get-WMIObject -computer $Computer win32_share | foreach {$shares += $_.name}

# Compare the Lists :

$Exist = 0
$Orphan = 0
$deleted = 0

$RegShares | foreach {
  if ($shares -eq $_) {

    "$_ Exists"
    $Exists += 1

  }Else {

    "$_ is an Orphan"
    $Orphan += 1

    # Only if DoChange is True Delete The Orphan Share

    if ($Remove.IsPresent) {$Key.DeleteValue($_);"$_ Deleted !!";$deleted +=1}
  }
}

# show some statistics :

"Existing : $Exists"
"Orphan   : $Orphan"
"Deleted   : $Deleted"

# changed -eq to -contains but not used anymore 

# "Orphan   : ";($RegShares | foreach {"$_ $($shares -contains $_)"} | findstr "False" | measure-object).count
# "Existing : ";($RegShares | foreach {"$_ $($shares -contains $_)"} | findstr "True" | measure-object).count



For more information about Orphan shares and the script see the old post,
Enjoy,
