 Windows 10 spreads the traditional deployment effort of a Windows upgrade, which typically occurred every few years, over smaller, continuous updates. With this change, you must approach the ongoing deployment and servicing of Windows differently. A strong Windows 10 deployment strategy begins with establishing a simple, repeatable process for testing and deploying each feature update. Here’s an example of what this process might look like:
 
-- **Configure test devices.** Configure test devices in the Windows Insider Program so that Insiders can test feature updates before they’re available to the Semi-Annual Channel. Typically, this would be a small number of test devices that IT staff members use to evaluate pre-releas builds of Windows. Microsoft provides current development builds to Windows Insider members approximately every week so that interested users can see the functionality Microsoft is adding. See the section Windows Insider for details on how to enroll in the Windows Insider Program on a Windows 10 device.

 - **Identify excluded devices.** For some organizations, special-purpose devices such as those used to control factory or medical equipment or run ATMs require a stricter, less frequent feature update cycle than the Semi-annual Channel can offer. For those machines, you must install Windows 10 Enterprise LTSB to avoid feature updates for up to 10 years. Identify these devices, and separate them from the phased deployment and servicing cycles to help remove confusion for your administrators and ensure that devices are handled correctly. 
 - **Recruit volunteers.** The purpose of testing a deployment is to receive feedback. One effective way to recruit pilot users is to request volunteers. When doing so, clearly state that you’re looking for feedback rather than people to just “try it out” and that there could be occasional issues involved with accepting feature updates right away. With Windows as a service, the expectation is that there should be few issues, but if an issue does arise, you want testers to let you know as soon as possible. When considering whom to recruit for pilot groups, be sure to include members who provide the broadest set of applications and devices to validate the largest number of apps and devices possible.
 - **Update Group Policy.** Each feature update includes new group policies to manage new features. If you use Group Policy to manage devices, the Group Policy Admin for the Active Directory domain will need to download a .admx package and copy it to their [Central Store](https://support.microsoft.com/help/929841/how-to-create-the-central-store-for-group-policy-administrative-templa) (or to the [PolicyDefinitions](https://msdn.microsoft.com/library/bb530196.aspx) directory in the SYSVOL of a domain controller if not using a Central Store). Always manage new group polices from the version of Windows 10 they shipped with by using the Remote Server Administration Tools. The ADMX download package is created at the end of each development cycle and then posted for download. To find the ADMX download package for a given Windows build, search for “ADMX download for Windows build xxxx”.
