The optimization of the services of Windows 7

A service is a Windows executable program that performs specific tasks and that, normally, is designed to not having any user intervention.
Usually services can also be used to form an intermediate layer on which application software can rely on to carry out specific functions.

Consider, for example, a service that offers X connectivity to the network interface and API specifications. Would it be possible to create an application that, based on the service, to connect to the network to perform specific operations (eg update the system date and time).

In other words, the services can costuitire an application layer on which other services and / or programs may base their operation.

Starting services

The windows services can be started in two ways:

• Automatically (at boot)
• Manually (by users - GUI or Shell - or other applications / services)

When a service starts, it normally runs (in the background) until the Windows operating system is booted. On shutdown or reboot of the system is shutting down active services. For those of you who are fond of Linux we can conceptually compare the services with daemons.

Different types of services

Before diving into the analysis of the services of Windows 7, a short introduction: in a Windows operating system there are three types of services:

• native services of the Operating System (Microsoft);
• services added as a result of an application (Microsoft or third party);
• services may be created by us (if we are programmers and we are able to do so).

It can often happen that the services installed by third-party applications are not actually necessary and that, therefore, in order to optimize performarce system, it is necessary to verify the behavior of these services.

The utility services

It is often said that a "service is futile": this is not true! Each service was created for one purpose and offer the features.
The fact that a service would be beneficial or not depends on your use of the operating system and applications but, in itself, there are no unnecessary services.

Access Services Manager

There are several ways to access the windows services manager. There mention three:

1) On the Run
Click the "Start", type "services.msc" and press Enter.
The screen below shows the Windows Services Manager.

2) Using the Control Panel
From Control Panel, click "Administrative Tools" (see below), then "Services". 3) From the Command Line - CMD
Using the command "sc query", you can see from the Windows shell (text mode) detailing all the services on the system.
