Create a Powershell ListBox Sticky Notes Backup Utility - powershell

Question

I'm building a PowerShell utility that will backup and restore sticky notes using a powershell script to pull the Get-localuser command from a local device into the list box. From list box choose the user profile and it initiates a comand to fetch a file. What im researching is after you select a user in list box, it sends a command to copy a file Thank you.
Example: Admin is the user:
%SystemRoot%\explorer.exe c:\users\Admin\AppData\Local\Packages\Microsoft.MicrosoftStickyNotes_8wekyb3d8bbwe\LocalState\pause copy plum.sqlite-wal cd C:\Users\Admin\Documents\SN Utility

If I understand your question correctly, i believe you want to replace the line
[void] $listBox.Items.AddRange(#("user1", "user2", "user3"))
with
Get-Localuser | select -expand name | foreach {[void] $listbox.Items.Add($_)}
or
$listbox.Items.AddRange((get-localuser | select -expand name))
