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

  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.
