Defragment and Optimize Disk won't open in Local Services

Defragment and Optimize Disks service is missing from list of Windows 10 services. It shows up on list of Administrative Tools in the Control Panel, but won't open even when using "Run as Administrator". I have run DISM /Online /Cleanup-Image /RestoreHealth
in the command prompt and it still does not fix the issue. I have uninstalled and reinstalled Defraggler, but still it does not show up on the local services list. I have run Dell Support Assist and no problems are found. All of this makes Norton Security
unable to Optimize Disk. Norton says it is a problem with the defragment app on Windows and were no help at all.

I am running a Dell Inspiron 5379 with 1TB HHD, 8GB ram and the latest updates of Windows 10 installed.

 

disk defragmenting

Sign in to your Windows 10 computer with an administrator account. It is important to use an administrator account because standard account holders cannot defrag the hard disk drive.

Click the Start button.

From the left pane of the Start menu, click File Explorer.

On the opened window, from the navigation pane in the left, expand the This PC tree.

From the expanded list, right-click Local Disk (C: ) or any other partition on which Windows 10 is installed.

From the context menu, click Properties.

On the opened Local Disk (C: ) Properties box, go to the Tools tab.

From the displayed interface, under the Optimize and defragment drive section, click the Optimize button.

On the Optimize Drives box, from the displayed list, ensure that the system drive (C: in this example) is selected.

Click the Analyze button from below the list.

Wait until Windows completes the analysis and displays the percentage of the fragmented files in the selected drive.

Note: If there are no fragmented files in the drive, Windows displays a message box stating that the disk does not need to be defragmented.

After Windows completes the analysis, click the Optimize button to start the defragmentation process on the selected volume.

Wait until Windows defragments the drive successfully, restart the PC, and start using Windows 10 normally.
