OK, many eye-blearying hours of reading up on DEP later and here is what I have managed to find out. Apparently, even Microsoft doesn't know how it works. Depending on which MSDN library article you read, the 32-bit version of Vista either does or does not support hardware DEP. Personally, I'm going to go with does, because this is dependent on whether the processor is NX or XD capable. If your processor IS NX or XD capable, see if you can disable this in the BIOS. That will take care of the hardware flavour.
The software DEP is configureable in many ways (we've already discussed a few), but guess what, YOU CAN TURN IT OFF. Vista does not use ntldr or boot.ini. It uses a registry hive called the Boot Configuration Data to configure the boot environment. This can be manipulated in several ways, the easiest being the BCDEdit function.
*****Before doing this, read lots on what you are about to attempt. You are about to modify your registry. Changes take effect immediately and can have severe consequences. By turning off DEP, you are disabling one of the security features in Windows that helps defeat buffer overrun types of attacks, to name one. Additionally, you may brick your system or render it unbootable. I do not recommend this solution, nor will I accept any responsibility for unforeseen consequences resulting from it. In other words....Your Call.*******
Open up a command line interface, the syntax is as follows;
*bcdedit /set [{ID}] nx AlwaysOff*
The optional {ID} is the GUID for the specific Windows boot loader boot entry that you want to configure. If you do not specify an {ID}, the command modifies the current operating system boot entry.
That's it, you're done. DEP is now off. Good Luck.
Personally, I would suggest getting the most up-to-date version of iTunes that you can. It should be DEP compliant.
