This question already has an answer here:

Sometimes when I delete a font through the control panel applet I get a message that it is in use. If I attempt to delete the file in %SYSTEMROOT%\fonts with farmanager it says that its locked by csrss.exe, the windows subsystem process. Obviously, there is some sort of IPC going on between csrss.exe and the process that actualyl uses the font. My question is how do I determine what process has a lock on the font?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
We already have a older topic where it's explained how to remove certain fonts that can't be deleted normally as they are in use. –  Karan Raj Baruah Apr 20 '13 at 14:53
    
@Justin This question wants to identify the process using the fonts, not just to remove them –  Tog Apr 20 '13 at 17:41

@tog If you look in the body of the allgeded duplicate, they wish to identify the process causing the lock as well. –  Justin Dearing Apr 20 '13 at 17:56
    
@justin maybe I'm being obtuse but I don't see a method of identifying the process and the question is marked as answered so it's unlikely to anytime in the future –  Tog Apr 20 '13 at 19:57
    
@Tog: Considering that it was the OP himself who marked his own question as a duplicate, perhaps we should defer to him? After all, I doubt he's all that interested in identifying the process, just as long as he can delete the font somehow. If none of the answers on the dupe help him then perhaps identification might make sense to see if the process can be (forcibly) terminated. –  Karan Apr 20 '13 at 20:37

Unlocker will tell you what is using it. Allow you to unlock, and then rename, move, or delete it. It may require a reboot, but it usually does not.
