The Drive Optimizer is one of the useful features built into the Windows 10 system, which improves disk performance with various optimizations. As early as Windows 10 May 2020 (20H1/Version 2004) was in beta, there were user feedback about performance issues with the tool, but this issue has not been properly addressed.
In a preview release in early January, users reported the issue to Microsoft. Then, in a preview released on January 23, Microsoft said it had fixed the problem. But it’s not clear exactly what the specifics are, and the problem remains in the official release of may be released on May 27th.
Themedia then tested the Windows 10 Version 2004 device on which the July cumulative update was installed and found that the diting tool was still not working properly, indicating that the application had not been repaired. The disk defragmentation tool does not report the correct status, or even record whether the scan has been run, warning that the disk is not optimized.
Because the drive optimization tool does not remember when the drive was last optimized, the Windows 10 Automatic Maintenance Tool also optimizes your SSD partition /defrag/TRIM after each restart. By default, Windows automatically maintains the disk every week, running in the background to optimize all of your partitions.
To solve the defragmentation issue, open Windows Search and find the defragmentation and optimize drive application. In the Drive Optimization tool, click Change Settings under Plan Optimization and click “Select” next to Drive. Now, uncheck your SSD drive, press OK, and then press OK.
