Win8 uses optimized drive to defragment disk

First slide the mouse to the lower right corner of the screen to bring up the Charm bar, then select Settings, then select “Computer Information”. At the bottom left of the "System" window, we are able to see the options for "performance information and tools".
Performance Information and Tools Portal

After entering the performance management interface, you can move your eyes to the "Advanced Tools" on the left. Here we can see a lot of performance management tools, including “ Open Performance Monitor ”, “Open Resource Monitor> and “Open Disk Defragmenter"
Advanced Tools

Click “Open Disk Defragmenter'; then we have entered the "Optimize Drives" interface. Analyze and optimize the disk here, and set the disk to be automatically optimized daily, weekly, or monthly in the “Change Settings” setting. This way we don't have to manually optimize each time.
