What is eKB?

What is eKB? Let’s explore the concept of eKB, which stands for “Feature Enablement Package.” Microsoft is constantly used nowadays to upgrade to new operating system versions like Windows 11 and probably Windows 12 also.

In the context of Microsoft, eKB can refer to an Enablement Package KB. An Enablement Package KB (eKB) is a package that makes updating to newer versions of Windows 11 faster and easier and requires only a single restart.

Instead of performing a full reinstallation or download of a large operating system update, the eKB is a more efficient way to enable the new features and changes introduced in the next version. By downloading and installing the eKB, the device can seamlessly transition from one version of Windows to the next without needing a full OS upgrade.

eKB is the method to upgrade to the next version of Windows, and eKB might only have 6 KB (6 kilobytes) in size. It is nothing but a feature enablement package. You would need to download eKB, a feature enablement package, to get upgraded from Windows 11 22H2 to 23H2, which is getting released in the coming months.

1903/1909 Servicing Windows Branches

Once a version of Windows, such as Windows 10, version 1903, is publicly released, its maintenance and improvement don’t stop there. Microsoft continues to provide regular updates every month.

These updates encompass security and non-security fixes, ensuring your operating system remains robust and protected. Traditionally, these updates are scheduled for release on the second Tuesday of each month, commonly known as “Patch Tuesday.” However, if a critical security fix is urgently needed, updates may be released “out-of-band” to address the issue swiftly.
