Vista: how to adjust services on the postponed autostart?
For what services with the postponed autostart are intended
the User of Vista who executed login right after its start faces some delay (sometimes quite long!) before control of the Desktop will come to the end and it will be possible to interact freely both with a cover of system, and with the started applications.
It occurs from - for the fact that during user login the dispatcher of management of services starts a set of the services Windows which are adjusted as services with automatic start and activated in the course of loading of system. These services at initialization intensively consume both computing resources of the processor, and resources of random access memory that brings to very noticeable (in comparison with the Windows XP) to delay of process of user login.
For fight against this problem the new type of start of services - the postponed automatic start is entered into Windows Vista OS . This mode can be applied to services which do not need to be active right after loading of system.
the Dispatcher of management of services starts the services which are adjusted on the postponed automatic start only after completion of start of all services which are adjusted on automatic start. To an initial stream of these services THREAD_PRIORITY_LOWEST priority (the lowest priority of a stream) is established. Installation of such priority leads to the fact that all operations of input-output which are carried out by a stream are carried out with a priority of Very Low (very low). When the service finishes initialization, the dispatcher of management of services establishes it a priority of Normal (usual).
leads the Combination of the postponed automatic start, a low priority of use of the central microprocessor and memory, and also a background priority of disk operations to essential decrease in impact of start of such services on process of user login, i.e. actually allows to accelerate user login a little.
