What are the Win7 system services?

1. Understand the basics of Windows 7 services. Compared with Windows XP and Windows 2003, compared with more than 70 services, the system has increased to more than 150 services in the Windows 7 era (more than 130 Vista systems). ), this inevitably increases the system resource usage, slows down the system speed, and occupies the system CPU and memory resources. Of course, in each version of Windows 7, the number of services that are loaded by default is significantly different. The most functional version is the Ultimate version (the Ultimate version), which definitely loads the most services. The number of service loads on Windows systems severely affects Win7's boot speed, so optimizing services is even more important. 2, how to set, open, close the various services of the Windows7 system 1) use the Win7 system comes with the service management software: Mode A, in the Win7 system at any time press the Win button + R key shortcut to open the run window, enter Services. Msc carriage return; mode B, click start menu —— enter "ld"; service & rdquo; two Chinese characters in the search box, or enter Services.msc carriage return; mode C, click control panel & mdash; & mdash; management tools & mdash; & mdash The service can also reach the same interface. 3, a comprehensive understanding of the Windows 7 system more than 100 services OK, the above said some guide operations for the primary users, also introduced to the Win7 optimization master comes with a service optimization master, then, the user is most concerned about There are also these problems —— Which services can be disabled in the Windows system? A service knows the name, don't know what it is? Ok, let's take a look at the list below —— In the list below, please note the various colors, service name description best suggestion second suggested service path .NET Runtime Optimization Service v2.0.50215_X86 The operation of technically written programs provides optimization. The default mode of operation for this service is manual and is not recommended for changes. \\\\WINDOWS\\Microsoft.NET\\Framework\\v2.0.50215\\mscorsvw.exe It is estimated that after using this technology, the program written by .Net technology will be more efficient, because the speed of running .Net programs in existing systems is still Some are slow. Application Experience handles application-compatible query requests when the application starts. The default mode of operation for this service is automatic and is not recommended for changes. \\\\WINDOWS\\system32\\svchost.exe -k netsvcs It is estimated that after using this technology, the system will automatically select the corresponding compatibility mode to run when running the old program, in order to get the best results. The Application Host Helper Service provides management services for IIS, such as configuration history and application pool account mapping. If you stop this service, the configuration history will not work, and you will not be able to lock files or directories with application pool-specific access control entries. \\\\Windows\\system32\\svchost.exe -k apphost IIS related stuff, if the average user recommends disabling. Application Information provides information for the operation of the application. The default mode of operation for this service is manual and is not recommended for changes. \\\\WINDOWS\\system32\\svchost.exe -k netsvcs The Application Layer Gateway Service provides support for third-party protocol plug-ins for Internet Connection Sharing. The default operation of the service is manual. If you connect to the network, the service will start automatically and is not recommended. \\\\WINDOWS\\System32\\alg.exe Windows XP also has this service, the role is similar, is the system comes with a firewall and open ICS shared Internet access services, if a third-party firewall is installed and does not need to use ICS to share Internet access, completely Can be disabled. Application Management provides installation, uninstallation, and enumeration of software for Active Directory (IntelliMirror) Group Policy programs for Active Directory. If the service is stopped, users will not be able to install, remove, or enumerate any programs installed using Smart Mirror. If the service is disabled, any other services that depend on the service will not run. The default operation mode of the service is manual. This function is mainly applicable to centralized management in a large enterprise environment, so home users can safely disable the service. \\\\WINDOWS\\system32\\svchost.exe -k netsvcs Background The Intelligent Transfer Service transfers data between the client and the server in the background. If BITS is disabled, some features, such as Windows Update, will not work properly. The default mode of operation of this service is automatic. The main purpose of this service is to use Windows Update or automatic update. It is best not to change this service. \\\\WINDOWS\\System32\\svchost.exe -k netsvcs Base Filtering Engine The Basic Filtering Engine (BFE) is a service that manages firewall and Internet Protocol security (IPsec) policies and implements user mode filtering. Stopping or disabling the BFE service will greatly reduce the security of the system. It will also cause unpredictable behavior in IPsec management and firewall applications. It is recommended to keep the default. \\\\WINDOWS\\system32\\svchost.exe -k LocalServiceNetworkRestricted Also provides dependency services for system firewall, VPN and IPsec, as well as system security services. If you use third-party VPN dial-up software and do not use the system firewall and ICS to share Internet access, System resources, close it, otherwise don't move it. Block Level Backup Engine Service Engine that performs block level backup and recovery. \\\\Windows\\system32\\wbengine.exe is estimated to be a service used for backup and recovery, without any dependencies. The default is manual, and it has never been seen before. Just let it go, don't worry. Certificate Propagation provides certificates for smart cards. The default mode of operation for this service is manual. If you are not using a smart card, you can safely disable the service. \\\\WINDOWS\\system32\\svchost.exe -k netsvcs It is estimated that when Vista is released, the password is not the only credential that can be used to distinguish the user's identity. Maybe smart card, or more convenient biometric technology, such as fingerprint, iris recognition, etc. The application will be more extensive. The CNG Key Isolation CNG key isolation service is hosted in the LSA process. The service provides key process isolation for private keys and associated cryptographic operations as required by general principles. The service stores and uses long-lived keys in a secure process that is consistent with general principles. \\\\Windows\\system32\\lsass.exe If the Wired AutoConfig/WLAN AutoConfig service is turned on and EAP (Extensible Authentication Protocol) is used, then this service will be used. It is recommended not to use automatic wired network configuration and wireless network. Turn it off. The COM+ Event System supports the System Event Notification Service (SENS), which provides automatic distribution of subscription component object model (COM) component events. If you stop this service, SENS will shut down and you will not be able to provide login and logout notifications. If this service is disabled, other services that explicitly depend on this service will not be able to start. A very primitive old service, the default operation mode of the service is automatic, this is an important system service, set to manual will also automatically run, set to disable does not seem to have any effect, but there will be a lot of errors in the log. We better not mess around.
