How to Run Defrag on Windows Vista, XP, 2000, ME, 98 & 95
The best way to start Defrag is to double click on “My Computer”, then right click on the “C:” drive and select properties from the list that appears…
From the next menu select “Tools” and then “Defragment Now”
The Disk Defragmenter screen will now appear, Click on Analyze. This will check your drives and will only take a few seconds. If your result shows a lot of red like mine (see picture below) then click on "Defragment" to continue) Be warned this may take several hours, so don’t run it, if you are going to need the computer in a rush. Some people tend to run it over night or before they go to work.
Once completed, shut down and use your computer.
