Microsoft is gradually rolling out the Windows 11 2026 Update (version 26H2) to compatible devices. However, it's an optional install, and if you want to install it early, you'll have to switch manually.
Windows 11 version 26H2 is a small update that doesn't require a full reinstall if your device is already running version 25H2 or 24H2. However, if your hardware is still running version 23H2 (or an older version), you'll need to perform an in-place upgrade with a full reinstallation.
Also, if you plan to upgrade from Windows 10, the computer will go through the full upgrade process as well. In addition, this new version will roll out in phases, starting with devices known to have a good upgrade experience, so not every device will receive the update in the early days.
If you don't want to wait, you can manually trigger the upgrade in at least four ways, including Windows Update, the Installation Assistant, the Media Creation Tool, and an ISO file.
In this how-to guide, I'll outline the steps to upgrade from any previous version to the Windows 11 2026 Update.
Important: Although this is a non-destructive process, something can still go wrong during and after the upgrade. Consider creating a temporary backup before proceeding. You've been warned.
To install the new version of Windows 11 through the Windows Update settings, use these steps:
After you complete these steps, the installation process will apply the update to the device without requiring a full operating system reinstall.
