Over time, a drive (both SSD and HDD) can begin to operate
with less efficiency. To speed up your drive, Windows 10 allows
you to defrag and optimize it using a built-in tool called
The Optimize Drives window presents a list of all of the drives
in your system that are eligible for optimization. If the disk
needs optimization, you’ll be able to click on ‘Optimize’
button and you will see a percentage complete progress
indicator somewhere in the Optimize Drives window.
Once done, Windows will tell you that your drive is optimized
and running without any problems.
Until May, Windows 10 correctly reported the status of your
drives, but with the May 2020 Update (version 2004), Microsoft
broke the tool and the
Drive Optimizer has been failing to log the status and history
of its scans.
Therefore, if you open the tool and check its history, you may
see warnings that your drive is due for optimization. In
addition, Windows 10 also tried to optimize your SSD drives too
often because it was unable to detect the history of the scans.
This could happen even when your storage is already optimized.
Earlier this month,
Microsoft told us that they were of the problem and a fix
is scheduled to arrive with August optional update.
Today, Microsoft has published a new update for testers in the
Beta Channel and it includes the fix for the defragmentation
According to the changelog of Build 19042.487, this issue has
now been resolved in Windows 10 20H2. After beta testing the
patch with Insiders, Microsoft plans to roll out the same
update to those with Windows 10 May 2020 Update (2004) later
this week or before September 1.
You’ll also receive these fixes if you skip the optional update
and install the September 2020 Patch Tuesday update instead.
