The four background services that the win7 system can't close are too important for

1. DNSClient Service

This is parsing DNS, in simple terms. If you disable this process, you can't access this website by entering www.355189.com. It can only be accessed by finding the IP address of this website. This will cause a lot of trouble for your daily use, so you can't disable it.

2. NetworkConnections Service

This service is for managing the network. Disabling this service will result in you not being able to access the Internet. I believe that you dare not disable it.

3. DHCPClient Service

The computer needs the service required for dynamic IP. If it is disabled, you will only be able to manually set the IP address. It is not recommended to disable it. Otherwise, it may cause you to be unable to access the Internet.

4. NetworkLocationAwareness(NLA) Service

Some configuration for collecting computer networks. If you disable configuration information for your network, it may not be available. There is a big probability that you can't get online.
