Earlier this year, the Windows content experience team moved all Windows 10 technical documentation from TechNet to docs.microsoft.com. The Docs platform offers improvements, such as responsive design that sales to your screen size, improved content discoverability, estimated reading time for each article, and the ability to download PDF versions of key content collections. The goal is to make it easier for you to search for and find the documentation you need to plan for, deploy, and manage Windows 10.
The next phase of this project has begun. Starting today, the technical documentation for Windows 8/8.1, Windows 7, and Windows Vista will also be available on docs.microsoft.com. Don’t worry - the information you need to support older versions is still available, and any existing bookmarks will automatically redirect.
