Add Optimize Drives Context Menu in Windows 10

Defrag Icon

Optimizing your PC's internal disk drive is a very important process which improves your PC's performance. In this article, we will see how to add "Optimize Drives" to the drive context menu in Windows 10.

Out of the box, Windows 10 performs disk defragmentation once a week for hard drives and SSD TRIM operation for SSDs. During active use, hard drive performance suffers due to file system fragmentation which notably slows down the access time. SSDs have very fast access times for data stored in any part of the drive and do not need to defragmented but they need to be sent a TRIM command which tells the SSD controller to erase unused blocks which are no longer in use, so that when the time comes to actually write new data to those blocks, performance isn't affected.

  1. Great tip!!
    Would there be a way to automatically trim the SSD when clicking the “optimize drive” command?
    Ya know, right click on the drive or even a blank space on the desktop and click optimize drives and it sends the command to the pc to trim the drive without any other input from the user?
