General Information
This service is used to transfer asynchronous data via HTTP 1.1 servers. BITS “continues” a download when you log back in after you log off or shutdown the system during a download. You may require this service for some, Windows Live Messenger, Windows Media Player or future .NET or Live functions.
Windows 8
Default Description
Transfers files in the background using idle network bandwidth. If the service is disabled, then any applications that depend on BITS, such as Windows Update or MSN Explorer, will be unable to automatically download programs and other information.
Additional Information
This service is used to transfer asynchronous data via HTTP 1.1 servers. BITS “continues” a download when you log back in after you log off or shutdown the system during a download. You may require this service for some, Windows Live Messenger, Windows Media Player or future .NET or Live functions.
Automatic Update still requires Windows Update, Cryptographic Services, Background Intelligent Transfer Service, and Windows Event Log to be running. Place all four in automatic if you do not wish to update manually. In addition, I recommend that you change the default time of 3 AM, for the automatic checking of updates, to a time when the system is “normally” on. Otherwise, Windows Update will check upon boot which may slow down the boot process.

With Windows Vista Retail, this service incorrectly listed Remote Procedure Call (RPC) needing BITS as a dependency. This has been corrected with Service Pack 1.

Windows XP Pro x64
Default Description
Transfers files in the background using idle network bandwidth. If the service is stopped, features such as Windows Update, and MSN Explorer will be unable to automatically download programs and other information. If this service is disabled, any services that explicitly depend on it may fail to transfer files if they do not have a fail safe mechanism to transfer files directly through IE in case BITS has been disabled.
Additional Information
This service is used to transfer asynchronous data via http1.1 servers. According to Microsoft’s site, Windows Update uses this “feature.” It “continues” a download if you log off or shutdown the system (that is, when you log back in). You may require this service for some MSN Explorer, Windows Messenger, Windows Media Player or future .NET functions.
It is very important that if you decide to disable this service, you check the Windows Update Version 6 web site often to ensure the latest patches install properly.
Take note: Manual updates via Windows Update Version 6 web site still requires Automatic Updates, Background Intelligent Transfer Service, COM+ Event System, Cryptographic Services, and Event Log to be running. Place all in automatic if you do not wish to update manually. In addition, I recommend that you change the default time of 3AM, for the automatic checking of updates, to a time when the system is “normally” on. Otherwise, Windows Update will check upon boot which may slow down the boot process.
