Log yourself off from old TS / RDP sessions. Remote computer name can be passed as a parameter, or on the pipeline. Useful if you have to log out of a lot of machines :)

Exit-TsSession.ps1

function Exit-TsSession {
	[CmdletBinding()]
	param(
		[Parameter(Mandatory=$True,
		ValueFromPipeline=$True)]
		[string[]]$computername
	)
    begin { 
        $username = $env:USERNAME
    }

    process {
        Write-Verbose "Computername: $computername"
        Write-Verbose "Username: $username"
        $session = ((quser /server:$computername | ? { $_ -match $username }) -split ' +')[2]
        Write-Verbose "Session: $session"
        Write-Verbose "Logging $username off from $computername..."
        logoff $session /server:$computername
        Write-Verbose "Done!"
    }
