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 installed version 2004 (build 19041.450) from scratch plus all Windows updates on a brand new SSD yesterday and noticed the bug.

    Better leave the automatic defrag OFF for SSDs for now.

    Gosh, is this Facebook where none reads the former postings? :-D

    After installation of KB4571744 the problem seems as resolved. 

    You may download the update manually as a CAB file from here:

    https://www.techpowerup.com/forums/threads/download-windows-10-esd.216164/page-31

    Then proceed as followed:

    • Download the CAB Files x86 / X64 depending upon the OS architecture
    • Rename file to KBnumber.сab (for example KB3176931.Cab)
    • Copy to folder C:\
    • Run command-prompt as admin (Right click on Windows icon and choose option). Check the image above.
    • Enter the command “DISM.exe /Online /Add-Package /PackagePath:c:\KBnumber.cab“
    • This installs the CU CAB File. Check the screenshots below for example.
    • Your devices will restart once the installation is over. Else you may need to restart your PC
