Optimize Drives, previously called Disk Defragmenter, helps to optimize the different types of drives that PCs use today. No matter which type of drive your PC uses, Windows automatically chooses the optimization that’s right for your drive.
By default, Optimize Drives runsautomatically on a weekly schedule during the time you have set for automatic maintenance. You can also optimize drives on your PC manually any time you like.
This tutorial will show you how to add or remove Optimize Drive from the context menu of all drives to make it easier to defrag a HDD and TRIM a SSD at will in Windows 8 and 8.1.
