I thought it would be valuable to summarize and compare the given answers.

</ul>

<h2>Comparison</h2>

@Kevin Panko's comment on @Mark Seemann's answer deals with choosing one of the categories over the other:

<blockquote>
 [The Windows access token approach] is the most secure answer, because $env:USERNAME can be altered by the user, but this will not be fooled by doing that.
</blockquote>

In short, the environment variable option is more succinct, and the Windows access token option is more dependable.

I've had to use @Mark Seemann's Windows access token approach in a PowerShell script that I was running from a C# application with impersonation.

The C# application is run with my user account, and it runs the PowerShell script as a service account. Because of a limitation of the way I'm running the PowerShell script from C#, the PowerShell instance uses my user account's environment variables, even though it is run as the service account user.

In this setup, the environment variable options return my account name, and the Windows access token option returns the service account name (which is what I wanted), and the logged in user option returns my account name.

<hr>

<h2>Testing</h2>

Also, if you want to compare the options yourself, here is a script you can use to run a script as another user. You need to use the Get-Credential cmdlet to get a credential object, and then run this script with the script to run as another user as argument 1, and the credential object as argument 2.

Usage:

<pre><code>$cred = Get-Credential UserTo.RunAs
Run-AsUser.ps1 "whoami; pause" $cred
Run-AsUser.ps1 "[System.Security.Principal.WindowsIdentity]::GetCurrent().Name; pause" $cred
</code></pre>

Contents of Run-AsUser.ps1 script:

<pre><code>param(
 [Parameter(Mandatory=$true)]
 [string]$script,
 [Parameter(Mandatory=$true)]
 [System.Management.Automation.PsCredential]$cred
)

Start-Process -Credential $cred -FilePath 'powershell.exe' -ArgumentList 'noprofile','-Command',"$script"
</code></pre>

I have used <code>$env:username</code> in the past, but a colleague pointed out it's an environment variable and can be changed by the user and therefore, if you really want to get the current user's username, you shouldn't trust it.

I'd upvote Mark Seemann's answer:
 [System.Security.Principal.WindowsIdentity]::GetCurrent().Name

But I'm not allowed to. With Mark's answer, if you need just the username, you may have to parse it out since on my system, it returns <code>hostname\username</code> and on domain joined machines with domain accounts it will return <code>domain\username</code>.

I would not use <code>whoami.exe</code> since it's not present on all versions of Windows, and it's a call out to another binary and may give some security teams fits.
