How did you get it to work on Win 7 64 bit. it will not on mine.
Thanks for the guide,
I have successfully installed O&O Defrag Professional onto my computer that runs Windows 7 64bit and it works without any problem.
My computer is much much faster now I was quite surprised must have been that year and half of use that really fragmented my PC.
Cheers for the serial key.
This works very well. Make sure you enter your e-mail as you Name and Company in the registration… not your name and company.
great inforamtion , now using O & O clever cache and it is a very good software thanks for the info.
Try MyDefrag. (at www DOT mydefrag DOT com)
It evolved from JkDefrag
Now it includes scripting capabilities so you can specify the defrag strategy yourself.
It still uses Microsoft's defrag APIs so stability is not affected.
