The WaaS model was introduced with the launch of Windows 10. This service delivery model represents a fundamental shift in the way Windows updates and upgrades have been traditionally conceptualized. It departs from the major release every few years’ approach to a more continuous update model, aimed at lowering implementation risks, reducing the cost of deployments, and more swiftly delivering security updates and new features.
Microsoft releases updates in the Semi-Annual Channel (SAC) which is designed for most systems, such as personal computers. For organizations, they recommend using these updates as important foundations in their deployment process and software update management (SUM) workflow.
Deployment and Release Models
Deployment in WaaS is majorly governed by two models: Pilot and Broad deployment.
- Pilot Deployment: The process begins with the identification and deployment of the latest release of Windows 10 to a select, representative group of machines within an organization for initial testing. This subgroup should represent the entire organization’s technological landscape. any issues here can be addressed before the next broader deployment.
- Broad Deployment: Post successful testing and rectification of any issues, the update is rolled out to the rest of the organization. By executing the broad deployment, organizations ensure that their entire technological infrastructure is up-to-date with the latest features and security updates.
Deployment Rings
One of the most important aspects of deploying WaaS is creating “Deployment Rings”. These rings essentially represent the sequential deployment groups to which the updates are rolled out. Deployment rings are crucial to the WaaS model as they allow IT administrators to manage the update process by identifying different groups for deployment, thus ensuring a smoother, more controlled implementation.
For example, organizations can create three deployment rings – Early Adopter, Pilot, and Broad. The Early Adopter ring will receive the updates first, followed by the Pilot ring for validation, and then the Broad ring for the rollout on a wider scale.
While WaaS presents a revolutionary approach to deploying updates and maintaining infrastructural relevance, it necessitates a change in the traditional approach towards deployments. The IT administration within organizations needs to reconfigure its functions to optimize the WaaS model, thus making understanding the deployment, release models, and deployment rings for Windows-as-a-Service (WaaS) an essential organizational task.
Next, we shall explore the various management tools and strategies for update compliance in line with the WaaS model. Stay tuned!

Interview Questions
What is Windows-as-a-Service (WaaS)?
Windows-as-a-Service (WaaS) represents a fundamental change in how Microsoft delivers Windows updates. Instead of large, infrequent updates, WaaS offers more frequent, smaller updates, helping to maintain the OS up-to-date and secure.
What is a deployment ring in the context of WaaS?
Deployment rings in WaaS are basically groups of machines that signify when (stages) their updates are deployed. These rings help organizations manage the broad deployment of Windows updates across their organization.
How many active release channels are there in Windows 10’s servicing model?
There are three active release channels in Windows 10’s servicing model: The Semi-Annual Channel (SAC), Long-Term Servicing Channel (LTSC), and Windows Insider Program (WIP).
What is the Long-Term Servicing Channel (LTSC)?
The Long-Term Servicing Channel (LTSC) is a release model that’s intended for specialized systems—such as PCs that control medical equipment, point-of-sale systems, and ATMs. LTSC releases don’t receive feature updates, offering only security updates.
How often are new features released in the Semi-Annual Channel (SAC)?
The Semi-Annual Channel releases new feature updates twice per year, approximately every six months, around March and September.
What is the purpose of the Windows Insider Program (WIP) in the WaaS model?
The Windows Insider Program allows for early access to new releases so they can be tested and provide feedback. This helps catch and fix issues before a broader distribution.
Can you manage the deployment of updates using Windows Update for Business?
Yes, Windows Update for Business is a set of management options built into Windows 10 that allows IT administrators to manage the deployment of updates.
What types of updates are provided through WaaS?
Through WaaS, Microsoft delivers feature updates (new functionalities), quality updates (security and reliability fixes), and driver updates.
How long is support provided for each release in the Semi-Annual Channel?
Each release in the Semi-Annual Channel is supported for 18 months from its general availability date.
Can a business stay on an older build of Windows forever without ever updating to a newer version?
No, to keep receiving support and updates, businesses should move forward to the latest builds. Older versions of Windows are backed by support for a limited period only.
