What O&O Defrag Professional actually does
O&O Defrag Professional goes well beyond the “Optimize” button built into Windows. The standout capability is boot-time defragmentation: it can optimize locked system files before Windows starts, something the built-in tool simply cannot access during a live session. The SSD-specific routines are genuinely thoughtful – rather than running generic defrag passes that add unnecessary write cycles, the software uses optimization methods tuned to flash storage.
The interface gives you two modes: a simplified one-click view for everyday use, and a full expert panel with per-drive scheduling, fragmentation thresholds, and multiple strategy options when you want that level of control.
Key features
- Defragments HDDs and SSDs using drive-type-specific optimization methods.
- Boot-time defragmentation for locked system files that cannot be accessed during normal Windows operation.
- O&O DiskCleaner to remove temp files, internet cache, and other accumulated storage waste.
- Automated background optimization with customizable schedules and fragmentation-threshold triggers.
- Drive health check that scans for file system inconsistencies and can attempt repairs.
- Full fragmentation analysis with visual drive status reports per drive.

What we think
O&O Defrag vs the alternatives
| Tool | Price | HDD defrag | SSD optimization | Boot-time defrag | Auto-schedule | Best for |
|---|---|---|---|---|---|---|
| O&O Defrag Pro (this giveaway, v30) | Free | ✅ | ✅ | ✅ | ✅ | Home users wanting a full optimization suite |
| Windows Disk Defragmenter | Free (built-in) | ✅ | ✅ (TRIM) | ❌ | ✅ (basic) | Anyone who needs nothing extra |
| Auslogics Disk Defrag Pro | $20.07/yr | ✅ | ✅ | ❌ | ✅ | Simple defrag with no extras |
| IObit Smart Defrag | $10.99/yr | ✅ | ✅ | ✅ | ✅ | Users who want boot-time defrag without paying |
Note: if your machine runs only SSDs and you’re on Windows 10/11, the built-in TRIM + Windows Defragmenter handles the basics for free. O&O Defrag adds the most value on HDD or mixed HDD/SSD setups.
Frequently Asked Questions
Is O&O Defrag safe to use on SSDs?
Yes. O&O Defrag uses the Windows file system APIs that Microsoft provides – the same interfaces Windows Explorer uses to move files. Its SSD-specific methods are designed to reduce write cycles rather than add them, so it doesn’t accelerate drive wear the way generic defrag passes might.
What’s the difference between the giveaway version (v30) and the current paid v31?
The giveaway gives you version 30, one release behind the current v31. Version 31 added O&O VisualDisk (a visual monitor of SSD write access), revised boot-time optimization that now works with Bitlocker-encrypted drives in a single click, and native ARM CPU support. None of those features are included in the v30 giveaway key, and the key receives no future updates.
Can I reinstall O&O Defrag after the giveaway period ends?
Yes. The giveaway terms confirm you can reinstall the software after the offer ends. Store your activation key somewhere safe — a password manager or a note in your email — before the giveaway closes.
Is this a one-time payment, or does it auto-renew?
Both the giveaway key and the paid license are one-time purchases. There is no subscription and no auto-renewal charge.
How many computers can I use the giveaway license on?
One. The giveaway license covers a single PC and is restricted to home (non-commercial) use only.

DON’T mix and match defragmenters from different vendors, choose ONE and stick with that one ONLY. Otherwise you will waste time and resources and drive life span reorganising files locations on the drive as each developer has their own idea of the preferred order they put files in and will be persistently re-arranging according to each developers preferences and wearing out your drive. Makes little difference both electro-mechanical and SSD devices hate regular unnecessary bulk defragmentations. Don;t forget all supported versions of windows have comprehensive defragmentation and disk optimisation built in and scheduled active by default. It’s really not a problem any more!
After entering my email to request a free license for “O&O Defrag Professional Giveaway: Lifetime Code Download,” nothing happens when I click on the “Request a free license” dialog box. I have tried this on two computers. This is the first time, using your site, that this has happened. What should I do?
Thank you.
Hi,
Please review our activation guide and try again.
O&O Defrag Pro is a good defragmenter. But if you want the gold standard for HDD defragmentation, then try PerfectDisk Business Professional.
It is the best defrag app I have ever used. Not free.
I’ve read on a number of sites that if you have an SSD drive, defragmentation is not recommended. https://www.howtogeek.com/855293/should-you-defrag-your-ssd/#:~:text=Defragmentation%20is%20not%20recommended%20for%20SSDs%20because%20it,these%20cycles%2C%20resulting%20in%20reduced%20performance%20over%20time
Defrag software was necessary in the late 90s and 00s, but with SSDs these days, they provide zero benefit.
If you have a HDD drive, you can get a cheap 120 GB SSD for 20 GBP.
This is purely snake oil.
