I recently noticed that whenever my laptop is an idle mode for a prolonged
time, DfrgNtfs.exe comes in. I understand that this Vista’s native Disk
Defragmenter.

Since I am using Raxco’s Disk Defragmentation Utility, which seems to do a
far better (and faster) job then the native Defragmenter, I would like to
turn DfrgNtfs.exe off so that it no longer runs when the system is idle.

The thing is, I can’t find any option in Vista (Ultimate) to do that. I
guess there must be some preset schedule in one of the task management
routines, but I sure can’t find it. Perhaps someone here can point me in the
right direction.

All help and advice would be much appreciated.
