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 have manually installed KB4571744 via the .cab file on Windows 10 20H2 "Release Preview Channel" on August 28, 2020 and the Optimize Drive Problem is correct as it should be after restarting. Of course, I don't forget tomorrow, September 8, 2020 for cumulative updates for Windows 10 Version 20H2. By the way I'm sleepy 😪 I'll take a nap first. Thank you very much everyone. Hopefully your defrag problem is what it should be after restarting.

    Thanks. Bye.

    FWIW ... I got a cumulative update yesterday 26/8, early evening KB4571744 which seems to have solved the defrag bug ... just checking through dfrgui, date and status of last trim seems to stay in place ... 

    I'm on the insider beta channel. Info under "other updates" in update history. 19042.487

    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).
