What's the difference between Windows ADK and WAIK?

Question

Windows

Correct if not.
Composition includes WAIK:

• ImageX
  
• DISM
  
• USMT
  
• VAMT
  
• winpe
  
• Windows SIM
  

Composition includes Windows ADK:

• DISM
  
• USMT
  
• VAMT
  
• winpe
  
• Windows SIM
  
• sysprep
  
• Win SQL Express
  

In fact, both kits include the same tools and, in fact, solve one problem - to deploy the Windows environment on the AWP, why are there two of these tools: do they have any different methods or are there any narrowly focused goals?
In general, I want to understand what for what and why.

Answer 1

WAIK is the Windows Deployment Kit
The ADK is the Windows Test, Evaluation, and Deployment Kit.
Therefore - WAIK is included in the ADK.
