Windows 10 Cumulative Update
Cumulative Update (CU), also known as quality updates, are required updates that provide security and reliability fixes that your device downloads and installs automatically each month through. Windows Update. Usually, cumulative updates are rolled out on the second Tuesday, week of each month – also known as Patch Tuesday. But sometimes you may also see releases delivered off monthly schedules.
These types of updates do not include new features, visual changes, or significant improvements. Instead, they are maintenance updates that fix bugs, fix security holes, and improve reliability with the current version of Windows 10.
They also increase capacity each month, as they are cumulative by nature, meaning that each update includes the changes available in previous updates. To help you reduce the burden on your network bandwidth and still get the equivalent update, Microsoft has designed three different types of updates:
– Full update contains all the required components and files that have changed since the last feature update. This is called the latest cumulative update, or LCU. It can quickly increase to a capacity of more than 1GB, but usually stays the same for the life of the supported Windows 10 version.
Express update generates different downloads for every component in the full update, based on some historical basis.
– Delta update only includes the components that changed in the most recent quality update. Delta updates will only install if a device has last month’s update installed. Delta updates include the full component (not just the individual files) that changed. They are therefore larger than quick updates, typically around 300-500 MB in size.
Microsoft allows Windows 10 Home and Pro users to defer quality updates for up to 7 and 35 days, respectively.
Windows 10 Feature Update
Feature Update (FU), also known as the Semi-Annual Channel (SAC) update, is a major update, similar to upgrading Windows 7 to Windows 8. Microsoft releases 2 feature updates in a year. to refresh Windows 10 with new features and improvements.
Before releasing these feature updates, Microsoft will release a Windows 10 preview build for Insider users to use to collect feedback. Once the update is proven reliable, it will roll it out to consumers and then to business customers.
Windows 10 feature updates are also downloaded and installed automatically on compatible devices. These major updates can be obtained through Windows Update or by manual installation. ISO files are also available for users who want a “clean” installation on their system.
Difference between Windows 10 Feature Update and Cumulative Update
Feature updates often include new features, visual and performance enhancements, changes and improvements to the overall user experience of the operating system.
By contrast, cumulative updates don’t bring features, visual changes, or even any significant improvements to Windows 10 – they’re simply maintenance updates. As a result, quality updates provide bug fixes, not new functionality during feature updates.
In terms of capacity, the feature update is much larger than the quality update. Download sizes can range from 2GB for 32-bit versions to 3GB for 64-bit versions and even 4GB if you use the installation media. Cumulative updates also increase capacity with each release.
Windows 10 Pro users can defer feature updates for up to 18 months after release. Your device will continue to receive cumulative and quality updates, but newer versions of the operating system will not be installed. Microsoft allows Windows 10 Home and Pro users to defer quality updates for up to 7 and 35 days, respectively.
Starting with Windows 10, 2004 edition, feature updates for Windows 10 Enterprise and Education editions (September scheduled) will be available for 30 months from release date.
Quality updates are downloaded and installed faster than feature updates, as they are smaller, and they do not require reinstallation of the operating system.
Install a Windows 10 feature update that changes the OS version (e.g., Windows 10 May 2020 Update version 2004) and installs the quality update that changes only the build number (such as OS build 19041.264) .
