Microsoft automatically updates Windows 11 to version 25H2 to maintain user security.
To ensure system security before Windows 11 24H2 support expires in 2026, Microsoft has begun rolling out automatic 25H2 updates using machine learning technology.
Microsoft has officially begun the automatic upgrade process for Windows 11 to version 25H2 for devices currently running version 24H2. This move aims to ensure stability and security for users before the older version's support lifecycle ends on October 13, 2026.
Automatic upgrade mechanism based on artificial intelligence.
The transition to Windows 11 25H2 will be done through the Windows Update tool. Notably, Microsoft uses an intelligent system based on machine learning to coordinate the distribution of the update. This system will automatically analyze and determine the optimal time to install, ensuring the device is in the most ready state and minimizing the risk of errors during the upgrade process.

Scope of application and user control
According to the manufacturer, this automatic upgrade primarily focuses on personal devices running Windows 11 Home and Pro editions. Enterprise computer systems or those managed by dedicated IT departments will not be included in this mandatory update, allowing organizations more time to test the compatibility of their internal software.
Because this is a crucial update for maintaining long-term support, users will not be able to completely refuse the installation. However, Windows still offers flexible options allowing users to postpone the installation for a certain period. Those who want to experience it early can proactively check and download it in the system settings.
Fixing technical bugs in the beta version.
Alongside the release of version 25H2, Microsoft has also just released an emergency patch, codenamed KB5086672. This is an effort to replace the preview update KB5079391, which caused serious installation issues with error code 0x80073712.
This issue often occurs due to corrupted or missing system files during the download process. The new patch not only completely fixes the old bug but also fully integrates previously anticipated performance improvements, making Windows 11 run more smoothly.
