This is general information about Microsoft's Background Intelligent Transfer Service (BITS). It is used by Windows to distribute updates and is used by Foray ADMAS WAN Connect.

SharpBITS

SharpBITS is a BITS client side job GUI. On Windows 7 it must be run using PsExec (see below) to see jobs created by the System account and even then it won't be able to kill them.

Download the SharpBITS WinApp from: http://sharpbits.codeplex.com/releases

Windows 7

On Windows 7 security makes working with BITS a bit more challenging. To see BITS jobs created by the System account PsExec is required.

Download PsExec from: PsExec http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

View all jobs

Open a Powershell session with Admin privileges
Run: .\PsExec.exe -i -s powershell.exe
This will give you a command prompt for the System account (sort of). Type whoami to see.
import-module bitstransfer
get-bitstransfer -allusers | select *

Run SharpBITS and see jobs for all users

Continue after step 2 above.
& 'C:\Program Files (x86)\SharpBITS\SharpBITS.exe'

Remove BITS jobs owned by System

Stop the Background Intelligent Transfer Service service

The service will automatically restart if the WAN Acquire Service or the Configure WAN Acquire app are running so be sure these are stopped and exited, respectively.
Delete files in: C:\ProgramData\Microsoft\Network\Downloader
Start the service
