Quick answer: For most Windows users, the built-in Optimize Drives tool is the right choice. Windows can defragment a traditional hard disk (HDD) and run the appropriate optimization, including TRIM, for a solid-state drive (SSD). Do not install an old “defrag booster” or repeatedly defragment an SSD.
What to know first
- Defragmentation rearranges scattered file data on HDDs; it does not repair bad sectors or recover files.
- SSDs do not need traditional defragmentation. Windows schedules drive optimization and uses TRIM where supported.
- Before troubleshooting a drive that is clicking, disappearing, or reporting errors, back up important files. Defragging a failing drive can add stress.
- Many utilities named in older versions of this article target Windows XP/Vista and are not current recommendations.
When should you optimize a Windows drive?
On a mechanical HDD, fragmentation can make routine reads less efficient, especially when the drive is heavily used or nearly full. Windows generally schedules optimization automatically, so manual runs are usually only useful when the schedule is disabled or Windows reports that optimization is overdue.
For an SSD, the Optimize Drives app performs the maintenance Windows considers appropriate. The process is not the same as repeatedly moving file fragments around as on an HDD. Leave the Windows schedule enabled unless a hardware or storage vendor has given you a specific reason to change it.
How to use Windows Optimize Drives
- Open Start, type Defragment and Optimize Drives, and launch the Windows tool.
- Check the Media type column to confirm whether the selected drive is a hard disk drive or solid-state drive.
- Select the drive and choose Analyze if that option is available. Windows may not offer the same analysis workflow for every drive type.
- Choose Optimize when Windows recommends it. Keep the computer powered on and avoid interrupting the operation.
- Check Change settings to review the automatic schedule. For most users, the default scheduled optimization is appropriate.
Windows’ own guide explains how to defragment and optimize data drives. If the drive reports errors, use Windows diagnostics and make a backup rather than assuming defragmentation will fix the hardware.
Should you use third-party defrag software?
Usually, no. Third-party utilities may offer visual maps or file-level controls, but those extras rarely justify installing an old or unmaintained program for routine maintenance. This older article previously listed tools such as PageDefrag, SpeeDefrag, JKDefrag, and versions of other utilities designed for legacy Windows releases. Compatibility and maintenance status can change, so do not treat that historical list as a current endorsement or download source.
If you have a specific need that Windows does not meet, verify the vendor’s official site, supported Windows versions, update history, and whether the tool behaves correctly for SSDs before installing it. Avoid utilities that promise to “repair bad sectors” or dramatically speed up every PC; software cannot repair failing physical media.
Practical troubleshooting
- Optimization is stuck: Restart Windows, confirm the drive is connected and has free space, then check again. Do not repeatedly force-stop it.
- Drive errors or unusual noises: Copy critical files to another device first. If the drive is failing, minimize writes and consider professional recovery.
- PC feels slow: Check free storage, startup apps, memory pressure, malware protection, and drive health. Defragmentation is not a universal performance fix.

Frequently asked questions
Does Windows 11 need a defrag program?
Most users do not. Windows includes scheduled drive optimization. Check the built-in tool before considering another utility.
Should I defragment an SSD?
Do not run repeated traditional defragmentation on an SSD. Let Windows Optimize Drives handle supported maintenance such as TRIM.
Can defragmentation repair bad sectors?
No. Defragmentation reorganizes data; it does not repair physical disk damage or restore lost files.
Is a third-party defrag utility faster?
There is no universal answer, and speed claims depend on hardware and workload. For ordinary Windows use, the built-in scheduler is the sensible default.
Our take
For routine maintenance, use Windows’ built-in Optimize Drives tool and leave its schedule enabled. The old software list is retained here only as historical context, not as a current download recommendation. We have not independently benchmarked third-party utilities for this update.

Manual and scheduled defragmentation in Windows is a thing of the past. No point in wasting time with something that can be performed more effectively and conveniently, automatically. Automatic defraggers, that function in real-time using idle resources, ensure that fragmentation is minimal at all times, without having to go through the hassles of manual/scheduled defragmentation.
This is a great list of what to use to keep your computer running good. Thanks for the info.
iobit defrag slower than Auslogics Disk Defrag but free and
also has a registry defrag in advance care system 3 also free.
jkdefrag is not the version below
jkdefrag 1.16 version (http://jkdefrag.8qm.de/english.php)
can defrag removable drive (e.g usb). but must be carefully use or else data gone using other option like cleaning hard drive.
Which of the defrag programs you offer will work on the A drive? I find that hard to sort out of the list you show; I do notice that the ones that do seem to list the drives appear not to acknowledge A.
I admit this request is old-fashioned of me, but I like to keep small matters on small devices.
Thank you.

@J Mead,
Try Auslogic Defrag Or Smart Defrag
I believe both this defragmenter software able to defrag floppy drive
