I'm not sure whether I'm posting it in the right forum. My question is about the Windows Internals book. I'm trying to determine which edition I should buy.
Each new edition is updated to cover a new version of Windows (4th edition focuses on Windows XP, 5th edition focuses on Windows Vista and 6th edition focuses on Windows 7). Are the changes from one edition to the other only incremental, or is material related to older versions of Windows deleted?
If I buy the 6th edition, will the theory and hands-on experiments in this edition be valid for understanding Windows XP? If I want to understand Windows XP and Windows 7, do I have to buy two different editions?
