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.

    Only windows system restore snapshots only should get defragged but drive optimization triggered by maintenance task or schedule defrags whole SSD for almos an hour.

    Yep I've noticed that too. I disabled automatic drive optimisation on all my PC and I just run a manual trim once a week or so.

    yes you are right. I know it. and it seems that when Idle 10 Minutes for example I do not find any suspicious Process in Task Manager or Bitsum Process Lasso (yes I use Process Lasso so that the CPU Cycle is not 100% CPU usage).

    related to Defrag.

    anyways i check it manually once a week (Analyze command). And when Above 11% (Need Optimization) for example. I defrag my HDD.

    I do not know why. My Laptop device is not affected after restart. because I still use HDD as storage media. unless Optimize Drive says: Never Run.

    that never run, is the problem, if you run, and after the restart it say again that never run, you have the problem

    when you are not watching and the windows maintanance starts, it will run again, dont matter if past one day, or 30 days, and if you have a SSD would defrag too for somereason

    i dont see any problem to defrag a SSD, but if done everyday that will degrade the SDD a lot sooner than planned
