Disk defragmenter not installed issue

Asked By 200 points N/A Posted on -


I noticed recently that my computer has become slow. So I decided to defragment my hard drive.

When I clicked on the disk defragmenter on my computer, I got an error saying that the disk defragmenter is not installed on my computer.

I think the disk defragmenter was not properly installed on my computer and do not know where and how to reinstall it.

I would like to defrag my hard drive, as soon as possible and would like to know how I can fix this error to get my defragmenter to work.

I looked in Program files, but it did not show up in my list of installed programs.

Thank you!
