How to disable DfrgNtfs.exe?

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.

Go to Control Panel, search on defrag, click on the option presented under
Administrative tools, elevate as needed, and untic Run on a Schedule. Ok
out.

The open task scheduler from Control Panel. In the left pane drill down
through Task Scheduler Library | Microsoft | Windows | Defrag. Disable one
or both of the two tasks for Defrag.

Hi Rock;

Thanks for that.

I did delete it from the task schedules before, but DfrgNtfs.exe came back
running when idle after the next system reboot.

Deleting it from the admin tools option fixed that problem - at least so far
I haven't seen it coming back.

You're welcome. Also note that at least one poster has reported that
although he disabled it through Administrative tools and disabled both tasks
in scheduled tasks, opening the defrag GUI in Administrative tools, caused
the system to scan all disks checking on their fragmentation status. This
slowed things to a crawl.

It doesn't happen on my system, and I never saw if he was able to resolve
that problem. Just FYI.
