Which services can be turned off in the Win7 system?

Many services and processes in the Win7 system are not used in normal times. These services and processes not only occupy a large part of the resources, but also affect the speed and security of the system. We can shut down those services and processes that are not commonly used to speed up the system, but for the average user, it may not be clear which ones can be closed and which ones cannot be closed, so let's take a closer look at the Win7 system.
