Windows 10 2004 optimization/defrag bug

the defrag / optimization bug is still NOT yet fixed, even with the newly released KB4565503 cumulative update for 2004 in mid-July.  disappointing to say the least :(

guess we'll have to wait for either a future non-security fix later this month or the next cumulative update in August to see if the problem would be fixed then

this is one of the results when MS fired much of their QA team several years ago - quality of new recent Win10 releases have not been good when first released to the public

I agree with you 100 %. BTW I just posted this https://answers.microsoft.com/en-us/windows/forum/all/is-this-it-for-july-2020-patch-tuesday/9b549cc4-9350-441c-9fd4-c632a5d42bbb

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.

Same problem here on 3 PC's with SSDs!

Good point, but the HDD trim  error in event log never occurred until MS messed up Defrag in 2004 update so I'm guessing Windows can identify a hybrid drive that supports trim and only trim hdd's that need it.
