In all versions of Windows you should have at a minimum 15% of the drive you are defragmenting free. The more space you have the more efficiently MS can handle the defragment.
The reason for this is during a defrag your OS is moving files around for more efficient access. I have come tp find if you have at least 30% free it will go A LOT faster! Defragment often and you will have a much speedier system. There are great ways for automating your defragementing like this article from AskTheAdmin.

Hi Roc2581. When you post a question on ITKE, please use tag(s) that best categorize your question. Your tag of “Rocky” has nothing to do with your question about defragging. I’ll change your tag to something that matches your question. Thanks for your cooperation in the future.

The built in requires about 15% but some third party utilities do it with leser free space. However its always a good idea to prevent fragmentation from growing beyond a certain level since it can take sluggishness to severe slowdowns and also cause freezes or lockups in advanced stages.
