If you'd like to become a Windows Insider -- someone who receives new builds of Windows 10 before they're ready for the public -- you can opt-in here.You can also choose how you want to receive insider builds -- in Fair warning: Being an Insider, especially an Insider on the fast ring, is more of a headache than a sweet sneak peek at new features.Microsoft makes no promises that your computer will work as advertised or even at all if you install Insider builds.In an Active Directory environment, you can use Group Policy to define how computers and users (referred to in this document as WSUS clients) can interact with Windows Updates to obtain automatic updates from Windows Server Update Services (WSUS).You can now activate Windows 10 using a Windows 7, 8 or 8.1 product key, which means you can do a clean installation of Windows 10 and still receive the free upgrade promised to older Windows users.To activate your copy of Windows 10, go to the Activation section and click Change product key, or click Go to Store if you'd like to purchase a different edition of Windows.
The Windows Insider Program now has its own section in the Update & security tab.
The second section contains a table that summarizes the differences in the default verses manual installation of WSUS in current and previous version of WSUS.
The third section contains a list and definitions about terminology used in this guide.
Windows Defender also has a section in the Update & security tab, though it hasn't been banished from the Control Panel like Windows Update.
In this section, you can toggle different Windows Defender options, including real-time protection, cloud-based protection, and automatic sample submission.
You can also add exclusions, or files and programs that will be excluded from any security scans, by clicking Add an exclusion.
