Windows 10 Defrag Not Working

My hard drive says that it is 22% fragmented and needs optimization, but when I run Windows Defrag, the fragmentation does not go down even though it goes to completion.

There is a possibility that this is due to corrupted files. Let's isolate the issue by performing the methods below:

The methods are listed in order, so start with the first one, see if that fixes the problem, and then continue to the next one if it doesn’t.

Method 1:
Perform a clean boot to eliminate software conflicts.

Method 2:
Run System File Checker to check for any file corruption.

Feel free to post back for the results.
