Bits started and then stopped

Background Intelligent Transfer Service (BITS) is a service built into Windows that transfers files in the background using idle network bandwidth. It basically acts as a download manager for Windows Update and other services by being able to resume from broken or partial downloads.

If you are having problems with downloading Windows updates because BITS will not start or is giving errors, there are a couple of ways you can try to fix the issue. If you are getting any of these errors, read on:

Background intelligent transfer service did not start properly

Background intelligent transfer service will not start

Background intelligent transfer service has stopped working

If BITS can’t be started for some reason, first make sure it is enabled in the Services control panel applet. Go to Start, Control Panel, Administrative Tools, and click on Services.

Make sure that Background Intelligent Transfer Service is set to Automatic or Manual as the startup type.

If it’s not set to Manual or Automatic, then double-click on it and change the startup type to either one of these. If the service is configured correctly, but BITS will still not start up properly, check to make sure none of the dependent services are disabled.

Again, go through the list of services and make sure all of the following are set to Automatic or Manual:

Terminal Services, Remote Procedure Call (RPC), System Event Notification, Windows Management Instrumentation Driver Extensions, COM+ Event System, DCOM Server Process Launcher

If all of the services are correctly configured, you can try to delete and reset the download queue by deleting the following two files:

%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr0.dat

%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr1.dat

Now try to start the BITS service by going to the command prompt and typing in net start bits. This will reset the BITS transfer queue and hopefully allow the service to start properly. If not, then continue reading!

If you are running Windows Vista and you cannot start the Background Intelligent Transfer Service, you can download the BITS Repair Tool to fix any problems corrupted BITS files. This tool by Microsoft tries three different methods to reset BITS on Vista

You can also check to make sure that a missing DLL file is not preventing BITS from starting properly. Go to Start, Run and type in the following command:

depends.exe %windir%\system32\qmgr.dll

The Windows Dependency Walker will pop up and you will get an error message if any of the required DLLs are missing. You also want to check the DLL dependencies for Windows Update:

depends.exe %windir%\system32\wuauserv.dll

If you simply get a window with a whole bunch of DLLs listed and no error messages that means all the appropriate DLL files for BITS and Windows Update are correctly installed on your system.

sfc /scannow

Afterwards, reboot your machine and hopefully your problem will now be fixed.

If the issue is still not fixed, it can be a very critical problem with your computer affecting your personal data and the Windows Operating System. You will have to chat with our Experts or you can check with your local technician to get the problems fixed with very high priority.
