The main reason for a sluggish computer is unavailability of essential resources. The applications and programs that you wish to open stall often because the resources required by these applications may not be available during the time of need. The windows 7 operating system is designed to efficiently allocate resources, but even the most efficient operating system can handle resource allocation only if sufficient resources are available.

When you purchase a computer or notebook, the manufacturers usually load the system with numerous programs which can start services while the operating system loads. Now, these services are meant to support applications that you may want to use. Many times, the windows 7 services simply run in the background without needed by any application. You can disable these rogue services to free up resources and CPU taken and reserved by those services. This will instantly result in performance boost because the resource hungry applications that you use will get all the necessary resources from the pool.

Some of the services that you can safely disable are Home group listener and provider, group policy client, offline files, portable device enumerator, windows search, software protection, certificate propagation and block level backup engine service. To disable these services, click Start button and type services.msc. Navigate to services and right click to select properties and then select disable. If you have installed security software, you can disable default security center and windows defender to free up even more resources.
