How to Repair the System Idle Process
System Idle Process is an interesting computer utility that does not harm the computer or use computer resources. It does, however, appear to do so, especially when a computer user checks the currently running processes and sees 99 percent of the CPU being used by System Idle Process. Computers were built to constantly run and process functions. When a computer is idle for several hours, a utility called System Idle Process automatically turns on and keeps the system busy. This, however, does not cause interference with other programs. A computer user repairs System Idle Process by shutting it down in Task Manager. Running programs such as email or anti-virus will keep the process from turning itself on, as the computer is busy running something else in the background.

Click on the "System Idle Process" listing.
Click on the "End Process" button, located to the right. The process will immediately disappear.

Open a computer program such as a Web browser or an anti-virus to give the computer a process to run.
