Windows 11 26H2, which overhauls Windows PCs, is now generally available
Microsoft has made the Windows 11 26H2 update, which it started rolling out gradually in recent weeks, available to all compatible computers.
The long-awaited update for Windows PCs began rolling out gradually in September: Windows 11 26H2. The update, which significantly reduces RAM usage and introduces system-wide performance improvements and bug fixes, is now available for download to everyone.
Microsoft has started offering the Windows 11 26H2 update, which it began rolling out gradually at the end of September 2026, to all compatible devices. The controlled rollout was conducted to prevent potential technical issues from affecting large user bases and enterprise systems.
Windows 11 26H2 Is Now Available for Download to Everyone
According to Microsoft's statement updated on October 28, 2026, devices running Windows 11 versions 24H2 and 25H2 can upgrade to the new version if they meet the hardware requirements.
Compatible computers benefiting from Windows 10's extended support program are also among the systems that can be upgraded to Windows 11 26H2.
Distributed via Windows Update, the update contains all the features announced in previous versions. Microsoft aims to shorten the installation time using its servicing technology, particularly for upgrades from recent versions of Windows 11. Additionally, it is reported that memory consumption decreased and performance increased on some systems using third-party tools developed to streamline core operating system components.
How to install the Windows 11 26H2 update?
Windows 11 26H2 is delivered to compatible computers via Windows Update. For users who cannot see the new version yet despite enabling the option to get updates as soon as possible in Settings, alternative installation methods are available.
Computers running Windows 11 24H2 or 25H2 can switch to the new version by manually downloading the eKB5121794 enablement package. The package unlocks features already present in the operating system that have not yet been activated. This allows the upgrade to be completed without requiring a full installation.
The enablement package works only on the specified two Windows 11 versions. This method is not supported on computers running older Windows 11 versions or Windows 10. These systems need to use a separate upgrade tool to move to Windows 11 26H2.
Install Windows 11 26H2 via ISO
Installation files have also been prepared for users who want to install Windows 11 from scratch instead of upgrading their current operating system. Microsoft made KB5127648 ISO files available through the official media creation tool. These files allow users to directly create Windows 11 26H2 installation media. Alternatively, preparing a bootable USB drive using third-party applications like Rufus or Ventoy is also possible.
Thus, users who want to switch to Windows 11 26H2 can choose between updating their existing system or reinstalling the operating system with a clean installation.
