Win7 Optimization Documentary 1 - Service Management

        Sometimes it is clear that there is no program running, CPU usage is still high, which is often caused by some Win7 self-starting services. The original intent of these services may be to optimize system performance and increase CPU utilization during idle periods, but in reality, for most users, these services are pits! We need to change to manual start or simply disable according to the actual situation. Here are a few services that once made my CPU usage up to 100%: SSDP Discovery Service Description: "When network devices and services using the SSDP protocol, such as UPnP devices, are discovered, they are also reported to be running on the local computer. SSDP devices and services. If you stop this service, SSDP-based devices will not be discovered. If this service is disabled, any services that depend on this service will not start properly. ” Corresponding process: svchost.exe Suggested processing method: changed from "automatic" to “manual", when the svchost.exe process occupies too high CPU, stop this service. (Because of the dependency, you need to stop the UPnP Device Host service first.) UPnP Device Host Service Description: "Allow the UPnP device to host on this computer." If you stop this service, all hosted UPnP devices will stop working and you cannot add other host devices. If this service is disabled, any services that depend explicitly on it will not be able to start. ” Corresponding process: svchost.exe Suggested processing method: changed from "automatic" to “manual", when the svchost.exe process occupies too high CPU, stop this service.
