Quote:With the release of Windows 10 version 2004, the Windows Defragger has become a mess as it starts to defrag SSD drives too often, perform trim on non-SSD drives, and forgets when it last optimized a drive.
 
Windows 10 includes an 'Automatic Maintenance' feature under Control Panel ->  System and Security -> Security and Maintenance that performs various maintenance tasks on a scheduled basis. This maintenance includes checking drives to see if they need to be optimized (defragged/trimmed), checking for new updates, security scanning, and other diagnostics.
 
When optimizing drives, Windows 10 should record the last time a drive is optimized so that it does not defrag a drive too often.
 
As noted by the members at WilderSecurity, with the release of Windows 10 2004, the Optimize Drives feature is not correctly recording the last time a drive has been optimized.
 
Due to this, when you go back into the Windows Defragger, you will see that an SSD drive says it 'Needs Optimization' even though automatic maintenance was run this morning, as shown below.
