CPU usage is a measure of how much of a computer’s processor is being used at any given time. It is typically expressed as a percentage, with 0% indicating that the processor is idle and 100% indicating that the processor is fully utilized. Checking CPU usage can be useful for identifying performance bottlenecks and troubleshooting computer problems.
There are several ways to check CPU usage in Windows Vista. One way is to use the Task Manager. To open the Task Manager, press Ctrl+Shift+Esc. In the Task Manager, click on the “Performance” tab and then select “CPU” from the left-hand menu. This will display a graph of CPU usage over time.
