Windows Resource Monitor is a tool to help you see your system resources are and find out what processes and services are using them. The resources are monitored in real time; making it easy to see what’s going on as it happens. Resource Monitor can help you analyze unresponsive processes, identify which applications are using files, and control processes and services. Windows Resource Monitor allows you to end or suspend processes and start, stop, or restart services. Be careful when doing this since some services can rely on other services to run properly.
To start Resource Monitor click on Start, click in the Start, then go to All Programs, click on System Tools and then Resource Monitor .Resource Monitor has 5 tabs: Overview, CPU, Memory, Disk, and Network.
