Other than support/updates, whats the difference between free and home versions?

I'm looking at the http://www.piriform....aggler/download download page, and I can't quite understand the difference between any of the versions, other than tech support. Even the free version updates automatically, despite the implication that the home version is the only one that "Automatically updates to the latest version!". The only real difference I see is this:

"Optimize your hard disks for faster access!"

Isn't that what all the versions are doing? Defragging is optimizing your HDs for faster access, so... whats the difference?

The download page can be somewhat confusing. If all you want is the free home version without support go here.

It doesn't update automatically for me, just notifies me that a newer version exists and provides a link.

Well I was able to download the free version just fine, I just didn't understand why anyone would be motivated to buy the home version. I assume the professional version is for multi-licensing.

Ah, I didn't actually test the feature, just noticed the "check for updates automatically" option in the installation.

Either way, its an awesome program! But I'm a little confused as to why it told me that my drive was 46% fragmented, when Windows 7 told me it was only 16% fragged. I'm also not really understanding the 'benchmark' feature; I finished the benchmark, but no results showed up or became obviously available. But I'm sure I will learn these things as I get to know it :)

Do this.

That seems to be about the frag % going up after each defrag. I'm just wondering why these two pieces of software are reporting different values at the same time; Is Defraggler limiting this % to just certain filetypes?

Windows defrag tool doesn't include many items in the count, such as Shadow copies and hibernates.

You can lower the count further by running a Boot Time Defrag 35bv39e.png or install Fixit 50463 to clear the Paging File at shutdown.

Thanks! I hadn't actually run a defrag yet, so I wasn't concerned about the effectiveness about either of the programs, just curious as to how they reached these different numbers.
