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.

    should be like you say, but because of this is defraging my SSD, my 2 new SSD have already 6 times it capacity write to them....

    There are several issues in the past, which causes a permanent write to SSD, not just this, for example a bug in Spotify, or Chrome for example, causing a write of 50GB or even more per day.

    Windows defrags ssds once a month ....with the new technology of ssds ....defragging once a month does nothing but keep the life of the ssd. Please do some research on ssds and windows. The only bug is that windows defrag wont retain the defrag history. You should set  auto maintenance to once a month is you have an ssd. Manual maintenance is in case of need to.

    Yes because windows is silly. Mac os x. Android. Linux. And virtually every other OS don't defrag ssds as its literally worthless. 

    This is nonsense..... people are just retards not knowing, that the Windows "defrag" tool has 2 functions:

    • defrag if it is a HDD
    • trim if it is a SSD

    Defrag tool wont ever defrag a SSD, it will send trim commands every week or so.

    the Defrag.exe, dfrgui.exe & defragsvc.dll files are still v10.0.19041.84 from the 2004 insider preview release from early 2020 and have not been updated for several months, while defragproxy.dll & defragres.dll files are still 19041.1.

    MS should issue newer versions of most of these defrag exe & dll files in future cumulative updates for 2004
