What are the differences between the Windows 8 editions available on MSDN?

Question

My DreamSpark account shows me several download links for Windows 8. I am not sure what is the difference between them and which one is suitable for me.

1. Microsoft Windows 8 with Apps 32-bit
2. Microsoft Windows 8 with Apps 64-bit
3. Microsoft Windows 8 Debug/Checked Build 32-bit
4. Microsoft Windows 8 Debug/Checked Build 64-bit
5. Microsoft Windows 8 SDK 32/64-bit
6. Microsoft Windows 8 Symbols 32-bit
7. Microsoft Windows 8 Symbols 64-bit
8. Microsoft Windows 8 Symbols Debug/Checked Build 32-bit
9. Microsoft Windows 8 Symbols Debug/Checked Build 64-bit
10. Microsoft Windows 8 WDF Co-installer 32/64-bit
11. Microsoft Windows 8 WDK 32/64-bit
12. Microsoft Windows Hardware Certification Kit 32/64-bit

I want to understand what each edition has to offer.

Answer 1

1. This is the default one. You want this if you run an x86 processor.
2. This is the 64bit version of 1. You want this if you run an x64 processor.
3. See: What are "Debug/Checked" versions of a Windows OS?
4. Same as above
5. This is only the Software Development Kit for Windows 8. You most likely won't need it.
6. These are just the Symbols for Windows 8. You most likely won't need it.
7. Same as above in 64bit.
8. Same as 6. But Checked again.
9. Same as 8 in 64bit.
10. Don't really know. Most likely driver development requirements as WDF is most likely the Windows Driver Foundation.
11. Same as above. WDK refers to the Windows Driver Kit.
12. Name pretty much says it all. I doubt you'll need it.
