For a user that is only on the computer a few hours a week and does not do much file saving and deleting. You rarely install and uninstall programs.

Hello Kev, and welcome to Vista Forums.

Yeah, I hear you. That's why I use the free Auslogics Disk Defrag when I do a manual defrag. You might see how you like it. :)

New here, When i used DF it took over 5 hours (its was a new laptop) and it took some of my GB off (this was before i had to wipe out my whole laptop and reinstall everything). Is this meant to happen? I haven't used it since.

Hello Moviefan, and welcome to Vista Forums.

I do not see how Disk Defragmenter could delete anything. It just reorganizes the hard drive to get rid file fragmentation.

For a faster alternative that includes a progress graph, you can might try the free Auslogics Disk Defrag.

My disk defrag is not running as scheduled. I have changed my scheduled time, but when I went to Task Scheduler to fix it where it would wake the computer to defrag, my Task Scheduler Library is empty. I can't find any reference to an empty library anywhere in the forums.

I can't get Disk Defragmenter to start. I've tried 4 times - once by typing dfrgui.exe into the Start Search box, twice by choosing Disk Defragmenter in Accessories>System Tools, and once by going to C:\Windows\System32\dfrgui.exe in Windows Explorer. In Task Manager, I can see that it starts for 1 second and disappears.

Hello Andy,

You might see if running a SFC /SCANNOW command may help if the file is corrupted. :)

I had just run an SFC before attempting to run Defrag. I also rebooted since posting. It still doesn't work.

I don't want to run it, but I want to see if it's running on a schedule or if it's off. There are plenty of utilities that will defrag, but they sometimes conflict with Windows Defrag. I'd hate to be defragging back and forth.

Sir, that is the link to page one of this discussion. This discussion is why I posted my "defragmenter won't open" post.

I tried reinstalling it by loading dfrg.inf, but it is not where it should be. I do have Auslogics Disk Defragmenter installed. Could that have removed the built-in defragmenter?

No, Auslogics wouldn't affect it. I'd say run the SFC scan a few times with a restart between each time to see if it may restore the file.

Andy-

Based on other problems you have had, such as the "default programs won't load", I have a suspicion that either you have some malware/virus or your Vista installation is corrupt. Please don't get mad at me for making such a statement but you've had problems with so many other Windows functions, it just begs the question about those things. I certainly can't reproduce these problems on two different installations of Vista, SP2.

Wither, I don't get mad at such statements. I just don't see how it helps me. I know that the system is not infected to a 99% certainty. Could I have had a previous infection that damaged Windows? Possibly. Have I run registry cleaners at times in the past 12 years? Yes, but I've also defragmented in that time using the built-in tool. I've also used third-party tools that I like better because they show graphically where I stand in the process. However, those tools also conflict with the built-in defragmenter. I could defrag with Windows then check with the third-party tool and be told that my disk got even more fragmented.

I was following along one of the tutorials for improving system performance and one of the steps was to defragment the drive. I was trying to follow the advice in this thread about defragmenting and getting it to run. It isn't working.

Internet searches found results that said third-party defragmenters could take over for the built-in. I also found that Task Scheduler had to be running for defrag to work. I went to Task Scheduler and it is running, but I got a persistent error. As soon as I open Task Scheduler, I get a dialog box that says:

"The task image is corrupt or has been tampered with.ManualDefrag"

When I click OK, I am let into Task Scheduler and it appears to work fine. Until I choose to look at the schedule for Windows Defrag and I get the error again. When I click OK, I am let into that schedule too. When I got into the schedule, it said it was last run November 2012. I selected to Run the task and it completed without telling me anything other than changing the last run to the current date. There was no dialog box at all to tell me it was running. Another search result said I can reinstall defrag using the dfrgui.inf file, but that is not on my INF folder. I have found a DfrgUI.exe.mui file, but I don't know if that will install Defrag or do something else.

Over the weekend, I ran a CHKDSK /r on each of my drives and several SFCs. No problems have been found except a non-writeable backup boot sector on a drive I don't boot from and will be removed shortly.

###########################################
EDIT: I GOT IT FIXED!! I followed the advice to repair Task Scheduler here: https://support.microsoft.com/en-us/kb/2305420

The Defrag User Interface now opens and it is defragmenting. I also happened to find that it is not automatically defragmenting because the trigger on the Scheduled Task is disabled even though the task itself is enabled.
