Question: How Do I Find My O&O Defrag Serial Number?

Before you can install O&O Defrag you'll need to find the serial number that came with the software. O&O Defrag requires that you enter a unique serial number.

If you've lost your serial number, there is a way to find it as long as O&O Defrag is still installed. You might be able to find your O&O Defrag serial number if you've uninstalled the program but only if the serial number information was left in the Windows Registry.

The O&O Defrag serial number is actually more of a product key than a serial number but as with most software, the terms are usually used interchangeably.

Answer: The best way to find your O&O Defrag serial number is with a product key finder program.

A free product key finder program will automatically search your computer's registry for your O&O Defrag serial number and for product keys and serial numbers for your other software programs.

The product key finder program that I've confirmed will find your O&O Defrag serial number is Magical Jelly Bean Keyfinder. If it doesn't find your serial number, try one of the other key finder programs that I linked to above and then let me know it didn't work so I can keep this page updated.

Most product key finder programs are designed to find the product keys for operating systems like Windows XP or Windows Vista but some of them find product keys and serial numbers for several other programs too, including O&O Defrag.

Important: You may have come across O&O Defrag keygen programs or other kinds of O&O Defrag cracks but keep in mind that these are not legal ways of obtaining serial numbers or product keys. The only legal way of installing this program is by using a valid O&O Defrag serial number obtained through a legal purchase of the software.
