This issue might occur because of the corrupt installation of third party defragmenter, or because the defragmenter isn’t compatible with Windows 10. To solve this problem, try some of the following solutions from this article:

Perform sfc/scannow

Sfc/scannow is useful Windows’ command which scans your computer for errors and provides you with appropriate solution. Performing this command could also solve the defragmentation problem. To perform sfc/scannow command, do the following:

  1. Go to Search, type cmd, and open Command Prompt with administrative rights
  2. Enter the following line and press Enter: sfc/scannow
  3. Wait until the scan is finished

If System File Checker found an error it will give you the solution (if available). If not, you might try with these other solutions listed below.

Check if Disk Defragmenter service is running properly

Maybe your Disk Defragmenter service is not running properly. This service is required for performing disk defragmentation, and if it’s disable, you won’t be able to run a defrag tool. Follow these steps to make sure that the Disk Defragmenter service is running properly:

  1. Go to Search, type services.msc and hit Enter
  2. Make sure that Disk Defragmenter service is set to manual
  3. Also, make sure that following services are set to Automatic:
    • Remote Procedure Call (RPC)
    • DCOM Server Process Launcher
