I hit Ctrl+Alt+Del and looked at my running processes and it showed “System Idle Processes” at 90%. What does that mean?
When you click on the Processes tab in Windows Task Manager you’ll see a column marked CPU. This tells what percentage of your RAM is being used. The value of this column must always add up to 100%.
Don’t worry though; System Idle Process is simply a placeholder process that lets you know how much space is not being used by other processes.
