- **Feature updates** will be released two to three times per year. As the name suggests, these will add new features to Windows 10, delivered in bite-sized chunks compared to the previous practice of Windows releases every 3-5 years. - **Feature updates** will be released twice per year, around March and September.

- **Quality updates** are released monthly, delivering both security and non-security fixes. These are cumulative, so installing the latest quality update is sufficient to get all the available fixes for a specific Windows 10 feature update. - **Quality updates** are released monthly, delivering both security and non-security fixes.

- **Servicing branches** allow organizations to choose when to deploy new features. Current Branch (CB) deploys the fastest, soon after a feature update is released. Current Branch for Business (CBB) defers the installation of the same feature update by about four months, until that feature update is considered ready for broad deployment. Long Term Servicing Branch (LTSB) is different, used only for specialized devices (which typically don’t run Office) such as those that control medical equipment or ATM machines that need to be kept stable and secure. - **Servicing channels** allow organizations to choose when to deploy new features. The Semi-Annual Channel receives feature updates twice per year. The Long Term Servicing Channel, which is designed to be used only for specialized devices (which typically don't run Office) such as those that control medical equipment or ATM machines, receives new feature releases about every three years.

## Key Concepts ## Key Concepts
New feature update releases are initially considered **Current Branch (CB) releases**; organizations will use these for pilot deployments to ensure compatibility with existing apps and infrastructure. After about four months, the feature update will be declared as **Current Branch for Business (CBB)**, indicating that it is ready for broad deployment. Windows 10 gains new functionality with twice-per-year feature update releases. Initially, organizations will use these feature update releases for pilot deployments to ensure compatibility with existing apps and infrastructure. After a period of time, typically about four months after the feature update release, broad deployment throughout the organization can begin. The exact timeframe is determined by feedback from customers, ISVs, OEMs, and others, with an explicit "ready for broad deployment" declaration signaling this to customers.
Each Windows 10 feature update (which initially begins as CB and then is declared as CBB) will be serviced with quality updates for a minimum of 18 months after it is released. The total length of time can be longer, as there will be two CBB releases serviced at all times. There will be a minimum of 60 days advanced notice (a grace period) after a CBB declaration occurs before an older feature update is no longer serviced. Each Windows 10 feature update will be serviced with quality updates for 18 months from the date of the feature update release.
Windows 10 Enterprise LTSB is a separate **Long Term Servicing Branch (LTSB)** version. Each release is supported for a total of 10 years (five years standard support, five years extended support). New releases are expected about every three years. Windows 10 Enterprise LTSB is a separate **Long Term Servicing Branch (LTSB)** version.

Because app compatibility, both for desktop apps and web apps, is outstanding with Windows 10, extensive advanced testing isn’t required. Instead, only business-critical apps need to be tested, with the remaining apps validated through a series of pilot deployment rings. Once these pilot deployments have validated most apps and CBB has been declared, broad deployment can begin.

This process repeats with each new feature update, two to three times per year. These are small deployment projects, compared to the big projects that were necessary with the old three-to-five-year Windows release cycles.

Additional technologies such as BranchCache and Delivery Optimization, both peer-to-peer distribution tools, can help with the distribution of the feature update installation files.
