If you want to change the automatic optimize schedule, click on Change settings. As I’ve written before, you shouldn’t defragment a SSD because it can reduce the life span of the device.
It’s worth noting that Windows can tell if the drive is a regular hard drive or an SSD and will defragment appropriately.
You can also click the Analyze button to quickly update the percent fragmented value. This will start the defrag process manually and you’ll see that Windows 8/10 does two passes to relocate fragmented data on the hard drive. You can manually optimize or defragment a drive in Windows 8/10 by selecting it and then clicking on the Optimize button. In Windows 8/10, the drives are automatically scheduled for optimization on a weekly basis. This will bring up the Optimize Drives dialog box where you will see a list of your drives and their current status (% fragmented).
