Get a list of all users who have checked files into a TFS Project

Have you ever wanted to get a list of all the users who have ever checked files into a TFS instance? Here's how to do so from PowerShell:

tf history * /format:detailed /recursive /noprompt | Select-String "User:" | Sort-Object | Get-Unique

Note that if you want this to appear in a GUI window, drop everything starting from "/noprompt".
