Win7 knowledge: ten essential services

1. Anti-Virus Software
 
2. DNS Client
Official explanation: the name of the DNS Client Service (dnscache) cache Domain Name System (DNS) and the full name of the computer. If the service is stopped, the DNS name will continue to be parsed. However, the query results of DNS names are not cached and computer names are not registered. If you stop this service, your computer will not be able to interpret the DNS information, and you cannot use a domain name to log on to the website.
 
3. Network Connections
Official explanation: Manages objects in the "Network and dial-up connections" folder, where you can view LAN and remote connections.
If you stop this service, you cannot configure the network, create a network connection, or access the internet.
 
4. Plug and Play
Official explanation: enables computers to identify and adapt to hardware changes with minimal or no user input. Terminating or disabling this service may cause system instability.
 
5. Print Spooler
Official explanation: load the file to the memory for printing later. You don't want to keep others' cards without it. This is the printing service.
 
6. Remote Procedure Call (RPC)
Official explanation: RPCSS is the Service Control Manager of COM and DCOM servers. It executes object activation requests for COM and DCOM servers, object Export Program parsing, and distributed garbage collection. If this service is disabled or disabled, programs that use COM or DCOM will not work properly. We strongly recommend that you run the RPCSS Service. This is very important (that is, very important). If you disable it, your system cannot start.
 
7. Workstation
Official explanation: Use the SMB protocol to create and maintain connections between the client network and remote servers. If the service is stopped, these connections cannot be used. If this service is disabled, any service explicitly dependent on it cannot be started. As the name suggests, If you disable it, your computer will disappear from the Intranet. Do not use medie to play with Microsoft's network resources.
 
8. Network Location Awareness (NLA)
Official explanation: Collects and stores network configuration information and sends a notification to the program when the information is modified. If the service is stopped, the configuration information may be unavailable. if the service is disabled, all services explicitly dependent on the service cannot be started.
This is a wireless network connection, but disabling it will cause a lot of problems.
 
9. DHCP Client
Official explanation: Register and update the IP address for this computer. If the service is stopped, the computer cannot receive Dynamic IP addresses and DNS updates. If this service is disabled, all services explicitly dependent on it cannot be started.
Disable the DHCP service. You only need to manually set the IP address.
 
10. Cryptographic Services
Official explanation: four management services are provided: directory database service, which is used to confirm the signatures of Windows files and allow the installation of new programs; Protected Root Services, it is used to add and delete certificates of trusted root certificate authorities from the computer, and the automatic root certificate Update service is used to retrieve root certificates and enable SSL from Windows Update; key service, used to assist in registering this computer to obtain a certificate. If the service is stopped, these management services cannot run properly. If this service is disabled, any service explicitly dependent on it cannot be started.
Disabling this encryption service will cause the computer security index to drop and cannot be automatically updated. ssl cannot be used.
