I'm buying this book Windows 10 In Depth (includes Content Update Program): Brian Knittel, Paul McFedries: 9780789754745: Amazon.com: Books in conjunction with the textbook by Microsoft for the 697 exam for Windows 10 MCP.

Per the authors this book comes with a FREE PDF version that is constantly updated as Microsoft changes or adds features to windows 10.

Sounds worth the $20...
