Windows 10 2004 optimization/defrag bug

Yours is one more addition to the list of problems with Windows 10 version 2004. I have had similar problems.

I do not have any solution to the problem yet.

Until then roll back to the previous version of Windows 10.

Here is how you do it:

Open Start Menu > Settings > Update & Security > Recovery. Here you will see Go back to an earlier build section, with a Get started button. Click on it. The process to revert your Windows 10 back will commence.

I dont think I can go back to the previous build as I removed my windows.old folder as I wasnt expecting any problems. 
In future I’ll keep the windows.old folder.  I usualky fo keep it but the 1 time I removed it is when I need it. 
I just disabled the automatic drive optimization and I’ll trim them manually one a week for now. 

I have the same issue with defrag. It's a bug that many insiders reported to Microsoft, even before 2004 was rolled out to the general public.  

There is not much you can do at the moment, just hope that they will fix it soon.  Do not carry out a manual maintenance, because, as you noticed, your SSD will be defragged, which is bad for SSDs.

So it only does it if I go to maintenance in control panel>security & maintenance and perform a manual maintenance? If I leave windows to do it's own thing it doesn't defrag in error?

I'll leave disk optimizer set to its weekly default setting and simply 'do not' do a manual maintenance? When windows does it's auto maintenance

It doesn't do the defrag error?

we can tell when Windows has done an auto maintenance as it shows up in control panel>security & maintenance.

It doesn't appear to be shown in known issue, so we'll have to wait and see.

feedback submitted. I had to condense it to make it fit, however I included a screenshot

I've reported it via the feedback hub, perhaps you could report it also. The more that report it the better.

I have never had this issue before build 2004, I'm on the insiders list but staying on retail builds. I've also not seen that using "dfrgui" the defrag window is actually trying to defragment the SSD. When I use manually use "optimize" it says "n% trimmed" but the status is not kept, right after that when leaving and restarting dfrgui it says "needs optimization". 
I got build 19041.264 installed on April 17th ... I mentioned this problem (and a few others) in the feedback hub, without getting feedback :-) 

I'm only seeing this issue if I go to Control Panel>Security and Maintenance and run the maintenance manually.

If you run the maintenance Control Panel>Security and Maintenance while also having the Optimize drives (defrag/optimize drives) open you will see it defrag then trim right in front of you.

You will only see it of you have both open at same time and do manual maintenance via Control Panel>Security and Maintenance. You will catch Windows doing it. Open Control Panel>Security and Maintenance and Optimize drives side by side and run manual maintenance (Control Panel>Security and Maintenance) and you will see it defrag briefly and then trim.

If you just open 'Optimize drives' only and select optimize then it will just trim it only.

You are actually saying that "defrag" on an SSD takes less time than a trim operation? 

Edit: Indeed when passing through "Security & Maintenance" it is doing a full defrag operation but it is anything but a brief message, it it going through the "full-all passes procedure" ... weird and worrying
