Windows 7: Built-in Disk Defrag not running scheduled defrags

Built-in Disk Defrag not running scheduled defrags

Built in Win 7 Disk Defragmenter is perfectly fine for my use except it seems to longer work properly, or at least how it did for several years.

I have scheduled defragmentation turned on. Pretty sure it is the default setting. Previously I would look and see that the listed drives, OS (C: ) HP_RECOVERY (D: ) and FreeAgent Drive (F: ) were Last Run on say 7/8/2015 7:00 PM (slight time variances for the three but all analyzed near the set schedule). But for a while now I will see the latter two have been analyzed but OS (C: ) was not. I then will manually analyze OS (C: ) and not think about it for a week or three and then will check and again see that two drives were analyzed on schedule but OS (C: )was not. It will still show the last time I manually analyzed the drive. So it would show 6/25/15 for OS (C: ) while the other two show 7/8/15.

I thought maybe it was because I have disturbed the program during use so I have made sure not to touch the computer around its scheduled time but OS (C: ) still does not get analyzed. It works fine when I manually run it so the program works. It analyzes the other drives on the schedule so it doesn't seem to be a Task Schedule issue. Any thoughts?

FWIW I am not over defragging my computer as even after analyzing I typically won't do anything more. Occasionally OS (C: ) may reach 3% defragmented and then I may let it defragment. I'm just trying to understand why it is not running the scheduled defragmentation for OS (C: ).

Some program of yours interfering and disturbing idle time perhaps? Does the scheduled task run when idle?

What would happen if you normally (not forcefully) shutdown when scheduled defrag is running? Is it okay since it knows it is shutting down? Also, how come processes such as the one for Windows Update after boot up after an update and background defrag process stay even after they are done doing...

Does Scheduled Defrags analyze the disk first?
I have my disk defragmenter set to run every Sunday at 6, yet sometimes I'll go back after 6 and do a disk analysis and I'll see that 1-2% is defragged! Does the scheduled disk defrag program not analyze the disk first? If that's the case it will never defrag anyway, right?
