How to Decrease CPU Usage in Vista

In a typical setup of Windows Vista a number of services, software features and viewing enhancements are installed by default. While these may offer the user some nice options, many are not absolutely essential for operation of the system. However, each one may consume part of the CPU power resulting in incremental decreases in performance. At some point, these may well cause unwanted slowdowns in computer operation. If you can live without some of these goodies, then CPU utilization can be improved.

Step

Press “Ctrl+Alt+Del” and select “Start Task Manager. “ Click on the “Processes” tab where you can get an idea of processes currently running and how much memory they consume. End ones you don’t really need like the Sidebar to decrease CPU usage.

Open the Control Panel and select the “Power Options.” If the Preferred Plan is not “Power Saver” chose this setting. Fine tune these settings by selecting “Change Plan Settings” and then “Change Advanced Power Settings.”
