XP process Optimization

Evaluation of an operating system, the most commonly used indicators include security, stability, ease of use and operational efficiency. Next, in this order, the service classification for Windows XP systems is described in one way or the other.

I. Services related to system security

The virus is rampant today, system security may be the most concerned about the problem, in addition to viruses. Outside the malicious program, Microsoft defaults to open System services, there are some issues worth rethinking.

1.Portable Media Serial Number Service

Description: Retrieves the serial number of any portable media player connected to this computer. If This service is stopped, protected content might isn't be down loaded to the device.

Process Name: Svchost.exe

This service appears to have only one role to report to Microsoft about the serial number of your Windows Media player player, but we really don't know if it also reports anything else, so I'm determined to disable it, which does not affect the use of WMP to watch online movies. TV.

2.Remote Registry

Process Name: Svchost.exe

When you put a CD or a U disk, the machine will automatically appear in the CD-ROM of the bootstrapper screen or ask what program to open a U disk file, this is the service of hard work results. Whether to turn off the use of personal habits, from a security point of view, I am still accustomed to disable it, so not afraid of CD-ROM from the START program entrainment malicious programs, and will not occupy a large number of system resources to run some unnecessary programs.

Second, related to system stability, convenient service

Today, a variety of widnows XP system optimization methods are countless, under the ghost Baojia, we can fully actively try. If you do not want to do too much of the high-risk test, but also to make their own operating system easy to use. Stable and compatible, do not disable the following services, this is my experience after the N high risk test summary.

1.com+ System Application

Description: Provides the load capability for the DCOM service.

Process Name: Svchost.exe

I don't know what Microsoft is thinking, the description of this important service is so short, and the description of those inexplicable services is so long and difficult to understand. I set it to automatic because it is set to manual and no program will automatically turn on the service when it is needed, and WPS OFFICE 2005 and Disk Management. You need to use it for disk-finishing programs. If you disable it, the system tray's small computer icon that reflects network connectivity will disappear, even if you unplug it. This service does not seem to have any actual connection to any network application, it can still use the local area network normally or use ADSL to dial. GPRS Internet access.

3.Event Log

Description: Enables viewing of event log messages issued by windows-based programs and components in Event Viewer. This service cannot be terminated.

The Security Center is just an interface that prompts this ah that, make people very annoying; System Restore doesn't help me any more. Automatic update upgrade, often appear some inexplicable problems, I do not believe that Microsoft is really doing service, in the eve of Vista launch, XP system, the more rotten, Vista prospects are more optimistic, Perhaps I think too crooked, but I insist that the Microsoft through the patch to deliberately destroy the XP system of this possibility, the user's dissatisfaction can be passed on to the hacker through propaganda. As for the other services can be disabled, think about it, have been streamlined, will be the day-to-day life needed?
