    The high CPU usage in Windows 7 will lead to so many problems. Some program in the computer might start automatically, when you start your computer. This program would prevent you to perform the other tasks in the computer. The speed and performance of the computer will decrease automatically. Some of these programs will create memory leak and it would not return to the Operating System resources when you quit.
    You will be able to see the current running processes in the Task Manager. You can open Task Manager by pressing ‘Ctrl’ + ‘Alt’ + ‘Delete’ keys. The Task Manager will show the CPU usage of all processes in the computer. You can see CPU usage history in the performance tab of the task manager. The Task Manager would help you to eliminate the opening applications in the computer.

    Your disk drives can be fragmented. In other words, the data stored in a single file is divided into multiple parts; thereby increasing the time required to load the file contents. Defragment it using the Disk Defragmenter.
    Click Start -> All Programs -> Accessories -> System Tools -> Disk Defragmenter. Select the disk drive and click “Defragment Disk” button.
    Similarly, the data stored in your system registry can also be fragmented. You need to defragment it using a third party registry defrag tool. Download Reginout registry defrag. Run it, close all other running programs, click Analyze button. If it shows that your registry is fragmented, then click the Defragment Registry button.
