Defrag has no Association

[Starla]

I try to use my defrag and i get an error "This file does not have a program
associated with it for performing this action. Create an association in the
Folder Options control panel" I have an emachine and it did not come with
Windows CD, it just gave me a serial number for it. I do not know how to get
this associated file.
Any options besides getting a new computer? Thanks

Click Start, Run and type:

mmc.exe dfrg.msc

Does that work?
