The update model Microsoft introduced with Windows 10. Rather than a new version every so many years with a new name (see Windows versions
), Microsoft releases "feature updates" and "quality updates" that retain the Windows 10 version name. See Windows 10 updates
and Windows 10 versions
Feature updates are large, semi-annual releases that are completely new installations. Users can defer updating for 18 months or even 30 months for Windows 10 Enterprise or Education editions.
Quality updates are known as "cumulative updates," "security updates" and "updates for Windows 10," which are automatically installed to fix bugs on the second Tuesday of the month (see Patch Tuesday
). Quality updates can be postponed for a month. See Windows Insider Program
Not Cloud Computing
Windows as a service (WAAS) moniker sounds like software as a service (SaaS), which is one of many available cloud computing offerings. However, WAAS is actually an update service. See cloud computing
