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.

    Sorry. I checked manually via the button "Check for updates" in Windows Update yesterday was the same. Except Definition Update For Microsoft Defender Antivirus. I'm sure it will be released this week or next week.

    FYI: I check for Updates Periodically Everyday Including Microsoft Store And Microsoft Defender Antivirus. And even if I missed Microsoft OneDrive Update for example. I still have PatchMyPC Home Updater running automatically through the Task Scheduler at 7:00 p.m.

    Thanks.

    Microsoft officially announced an update rolling out in late August that will fix this issue. Source (german): https://winfuture.de/news,117684.html

    thanks. It doesn't matter if I read in German. Because there is already a built-in translation in the new Microsoft Edge (based on Chromium).

    My windows is automatically downloaded the update. It turns the function back on. But its still not works properly. After every restart it seems like optimisation never runs.
