Background Intelligent Transfer

ServicesIntroduced in Windows XP and also used in Server 2003, Background Intelligent Transfer Service (BITS) is similar to a download manager. It only tries to download using available bandwidth, functions in the background, and is tolerant of disconnections. BITS can also upload files, and in the Vista version is now capable of doing peer-to-peer. Most notable of the features that use BITS is Windows Update. For a history of BITS, see this page. Most people will not want to disable this service, but if you are on a metered internet connection where you need more control over how much is downloaded and when it happens, you may wish to disable this service (knowing Windows Update and possibly other features may not function properly).

Application Management

ServicesAvailable only in the Business, Enterprise and Ultimate versions of Vista, the Application Management service makes possible the installation of applications through a Group Policy Object (GPO). If your computer is not a member of an Active Directory, or your system administrator doesn’t distribute software via GPO’s, then this service is not needed. Note that because the default startup mode is manual, this service does not use any resources unless called upon, so you won’t gain anything by disabling it.

Application Layer Gateway

ServicesInternet Connection Sharing (ICS) is a way for multiple computers to share one internet connection without using a router. The Application Layer Gateway service helps extend the functionality of ICS by allowing protocol plugins. If you’re not using ICS, you don’t need this service, though because the default startup is manual, it’s not using any resources if ICS isn’t in use, so there is nothing to gain by disabling it.

Application Information

ServicesThe Application Information service (AIS), introduced in Vista, is responsible for creating a new process to run applications with elevated privileges. You’ll typically see this happen when running an administrative application while having UAC turned on. If you disable this service, you won’t be able to run applications with elevated privileges, which means you won’t be able to manage your services to enable it again. If you somehow accidentally disable it, boot into safe mode to get access to your services so you can enable it again. Continue reading “Application Information”

Application Experience

ServicesIntroduced in Windows Server 2003 as Application Experience Lookup Service, Application Experience is basically a database of third-party applications that have problems running properly on Vista. If Vista sees a program from this database, it will alter it’s behavior in some way (create a compatibility shim) to help the program run smoothly. This could be anything from redirecting a registry setting that’s trying to insert itself in the wrong location to assisting with window redraws. Continue reading “Application Experience”
