Powershell: Set registry key

The New-Item CmdLet is used to create a registry key normally:
New-Item -Type String "HKLM:\Software\Example"

This works fine but that can be a roundabout way if you need to create a key whose subkeys are not existing:
New-Item -Type String "HKLM:\Software\Example"
New-Item -Type String "HKLM:\Software\Example\Sub1"
New-Item -Type String "HKLM:\Software\Example\Sub1\NewKey"

Last but not least, you have to set the value:

Set-ItemProperty "HKLM:\Software\Example\Sub1\NewKey" "Name" -value "John Doe" -type String

With the following function you are able to set an registry key and its value:

Function New-RegistryKey([string]$key,[string]$Name,[string]$type,[string]$value)
{

    #Split the registry path into its single keys and save

    #them in an array, use \ as delimiter:
    $subkeys = $key.split("\")

    

      #Do this for all elements in the array:

    foreach ($subkey in $subkeys)
    {

        #Extend $currentkey with the current element of

        #the array:
        $currentkey += ($subkey + '\')

        #Check if $currentkey already exists in the registry
        if (!(Test-Path $currentkey))
        {

            #If no, create it and send Powershell output

            #to null (don't show it)
            New-Item -Type String $currentkey | Out-Null
        }

     }

     #Set (or change if alreday exists) the value for $currentkey

      Set-ItemProperty $CurrentKey $Name -value $Value -type $type 
}
Function Call:
New-RegistryKey "<PATH>" "<NAME>" "<DATATYPE>" "<VALUE>"

Datatypes:

• String
• ExpandString (for use with environment variables)
• Binary
• DWord
• Multistring
• QWord

Example:
New-RegistryKey "HKLM:\Software\Vendor\MySoftware\2012\Example\Another\Key\StopHere" "Name" "STRING" "John Doe"

NO GUARANTEE THAT THIS FUNCTION WORKS WITHOUT ANY ERRORS IN YOUR ENVIRONMENT - PLEASE TEST IT FIRST!
