Which services in the Win 7 system cannot be banned

Win 7 system lends powerful functions and beautiful interface. It has replaced XP as the most operating system in the world. I believe many of my friends have used Win 7. In order to speed up the running speed of Win 7, many friends have chosen to prohibit some services running in Win 7 system, but in fact not all services can be banned, the following will introduce you to the Win 7 system which services can not be banned?
1. DNS Clientz: The DNS Client Service (dnscache) caches the Domain Name System (DNS) name and registers the full computer name of the computer. If the service is stopped, the DNS name will continue to be resolved. However, the query results for the DNS name will not be cached and the computer name will not be registered. If you stop this service, your computer will not be able to interpret the DNS information and cannot log in to the website with a domain name.
2. Network Connections: Manage the objects in the "Network and Dial-up Connections" folder where you can view LAN and remote connections. If you stop this service, you can't configure the network, you can't create a network link, and you can't go online.
3. Plug and Play: Enables the computer to recognize and adapt to hardware changes with little or no user input. Terminating or disabling this service can cause system instability.
4. Remote Procedure Call (RPC): The RPCSS service is the service control manager for COM and DCOM servers. It performs object activation requests for COM and DCOM servers, object exporter parsing, and distributed garbage collection. If this service is disabled or disabled, programs that use COM or DCOM will not work properly. It is highly recommended that you let the RPCSS service run. If you disable it, then we can't start the system.
5. Workstation: Use the SMB protocol to create and maintain a connection between the client network and the remote server. If this service is stopped, these connections will not be available. If this service is disabled, any services that explicitly depend on it will not be able to start. As the name implies, it is forbidden, your computer will disappear on the intranet, and don't even want to use media to play Microsoft's network resources.
6. Network Location Awareness (NLA): collects and stores configuration information of the network and notifies the program when this information is modified. If you stop this service, the configuration information may not be available; if you disable this service, all services that depend on this service will not start. This is a wireless network link, but it is forbidden to have a series of problems.
7. DHCP Client: Register and update the IP address for this computer. If this service is stopped, the computer will not be able to receive dynamic IP addresses and DNS updates. If this service is disabled, all services that explicitly depend on it will not be able to start. DHCP service is forbidden, you only have to set the IP manually.
8. Anti-virus software service: Of course, the security of our system also needs to be protected by anti-virus software at any time, so please do not turn off your anti-virus software service without special circumstances.
