Microsoft Rolls Out Windows 11 26H2 Official Release, Measured Boot Memory Drops by 1.6GB — Is There Hope for Older PCs?

On September 30, Microsoft officially began rolling out the Windows 11 2026 Update — Version 26H2 — to eligible PCs via a small enablement package (eKB). (Note! This is a genuine official release this time.) This update consolidates all features and security improvements from the 25H2 branch over the past year, with the first monthly update arriving on October 13.

System Memory Usage Drops Significantly

First, some measured data. On the same PC, after upgrading from 25H2 to 26H2, system memory usage at boot dropped from 9.1GB to 7.5GB — a full 1.6GB less. Numbers will vary across different hardware configurations, but the optimization direction of "lower memory usage after upgrade" is a genuine boon for users with limited RAM. In the 5 years since Windows 11 launched, 26H2 is currently the most older-PC-friendly version.

File Explorer Starts Doing AI's Work

26H2's File Explorer adds several productivity features: it can generate summaries directly for documents in OneDrive and SharePoint, supports AI-powered image operations, and can quickly handle work and school accounts. Archive support has also expanded — more formats can now be extracted directly within File Explorer.

Search Finally Looks for Files First, Web Pages Second

Windows Search's focus this time is "prioritizing local content." The system now includes an option to disable web search results, so entering keywords prioritizes matching local files and apps. Error correction has also improved: according to testing by Windows Latest, typing "pwerp" correctly matches the local PowerPoint, and typing something like "tskm" — with both missing and extra letters — can still find Task Manager. Frequently used folders are automatically indexed, so you no longer have to dig through directory levels to find files.

Start Menu and Taskbar Can Now Be Arranged to Your Habits

Personalization is the most visible part of this update. The taskbar is no longer limited to the bottom — it can be placed on any of the four sides; a new compact taskbar mode has been added; the Start menu has a brand-new view and size adjustments, and you can even hide your name and avatar in the menu — very practical for presentations and screen sharing. On the accessibility front, Magnifier adds zoom and screen color options, Narrator gains a Braille viewer, and the voice assistant on Copilot+ PCs has expanded natural language commands.

Upgrade Paths and Support Lifecycle, Explained in One Table

Another key point of this update is the recalculation of support lifecycles. How each version upgrades and how long support lasts — just check the table:

For devices upgrading from 24H2 or 25H2, the downloaded update itself is the eKB that activates 26H2 features — the process is roughly the same as installing a monthly cumulative update. Devices on the two older servicing branches, 22H2 and 23H2, will need to download the full feature update package.

Currently, 26H2 is only available through Windows Update, with ISO files expected to be released soon.

One more easily overlooked piece of information: according to Microsoft's support documentation, the next major version after 26H2 will no longer support devices based on the Snapdragon 850 processor. This early Windows on ARM chip, released in 2018, can still upgrade to 26H2, but this is essentially its last stop on the official support list.

For most users, the practical benefits of this upgrade come down to three things: lower memory usage, smarter local search, and more freedom in the taskbar and Start menu. Which version is your PC currently on — are you ready to upgrade to Windows 11?
