PowerShell 6 version of Set-Owner

[jzabroski]

Set-Owner does not work on PowerShell 6 due to referencing .NET Framework assembly APIs. .NET Core has refactored these APIs, and they no longer work in PowerShell 6 because the API is not there.

The following is a simpler Set-Owner script:

#
# IMPORTANT: Run with ELEVATION
#

# The target folder.
$folder = 'C:\Temp'

# Specify the new owner, which can be a mere username ('John.Doe'), a well-known
# security principal ('BUILTIN\Administrators'), or a UPN ('John.Doe@example.org')
$newOwner = 'BUILTIN\Administrators'

# Get the current ACL...
$acl = Get-Acl -LiteralPath $folder

# ... and assign the new owner...
$acl.SetOwner([System.Security.Principal.NTAccount] $newOwner)

# ... and set the modified ACL.
Set-Acl -LiteralPath $folder -AclObject $acl

"New owner: $((Get-Acl -LiteralPath $folder).Owner)"

UPDATE:

I realize now that your Set-Owner solves some "un-foreseen issues": https://learn-powershell.net/2014/06/24/changing-ownership-of-file-or-folder-using-powershell/
