Windows 10 2004 optimization/defrag bug

Hi all

I've just completed the Windows 10 2004 upgrade and I have noticed 2 issues.

  1. When I manually trim my SSD in the drive defrag/optimize tool in windows and I reboot it says 'never optimized' when i go back. I heard this was a bug in insider preview which they obviously didn't fix. 
  2. I happened to have the defrag/optimize tool open at the same time as Control Panel\All Control Panel Items\Security and Maintenance, I initiated a manual maintenance and I caught windows defragging my SSD and then it trimmed it straight afterwards. If i click the optimize button in defrag/optimize tool it only trims it and not defrag.

This seem to only happen when Control Panel\All Control Panel Items\Security and Maintenance initiates its automatic maintenance or if I select start maintenance.

This is concerning as it should never attempt to defrag an SSD.

My laptop is only a few months old and came with a PCIe SSD and Windows 10 1909 so there is no compatibility or lack of trim support issues obviously.

I have disabled scheduled weekly optimizations in the defrag/optimize tool which prevents it from attempting to defrag when the control penal maintenance attempts its maintenance when the computer is idle.

I want to let everyone know that this is happening so others are aware. My other computers that have the latest update are also doing it.

    I've also installed the preview update, and yes, things do look a lot better.

    I do however have a large capacity FAT32 formatted conventional drive which is still giving a problem.

    It does the first opimising pass fine, although it takes ages, and then moves on to the "consolidating" phase.

    This remains stuck on 1%. I've left it for hours, and it never moves on.

    Anyone else seeing this? I don't know if it's because it's a FAT32 drive, but if it can optimise it, it should surely be able to complete the process!

    Cheers, Dave.

    Was that always the case with version 2004 or just since the update?

    Can you download any utility from the manufacturer to check the disk or run chkdsk /r command on the drive.

    I'm not sure if the problem was there before the 2004 update, I never really paid much attention to it until I became aware of the recent issue with the defrag/TRIM system.

    After a reboot it did say that the drive was 0% fragmented, so I supposed that was a good sign.

    It passed chkdsk fine, that's the first thing I checked to make sure there was no corruption on the drive!

    I have a dual boot system, with Windows 10 and Windows XP, and I've tried running the Windows XP defragger on the drive, and it said it was still quite fragmented, so I guess the Windows 10 one didn't actually do its job.

    The Windows XP defragger is now defragmenting it (taking ages) and when it's finished I will try running the Windows 10 one again to see if the result is any different now the drive should actually be defragmented.

    Thanks, Dave.

    seems that the last optional update solved the problem, i tested a few times and no problem anymore.
