Windows 10 gets its final update before support ends. What’s in it?

Windows 10 support officially arrives at the end of next month with a last update on October 14, 2025. Yesterday, Microsoft published a preview version of this cumulative update, which is optional to install but available if you want to get ahead of the curve.

Known as update KB5066198, it brings Windows 10 to build 19045,6396. This update does not contain new features for Windows 10, which would be more than surprising at this stage. Instead, he corrects two bugs that Microsoft wanted to approach.

In the update assistance document:

[SMBv1 protocol connectivity (known issue)] Correction: A problem where you may not be able to connect to shared files and folders if you use the V1 protocol of the server messages block (SMB) on NetBios via TCP / IP Netbios (NetBT). This can happen after installing the KB5065429 update.

[Autopilot Enrollment Status Page (ESP) (known issue)] Fixed: A problem when using the Windows automatic driver to deploy Windows 10, version 22:2h on the devices with the Registration State (ESP) page configured may find that ESP does not take care during the out -of -box (Oobe) experience.

These are problems likely to affect a small number of users. You can get the KB5066198 update now via Windows Update or manually from the Microsoft Update catalog.

Windows 10 End of the support in view

As mentioned above, this seems to be the final update of Windows 10 which provides real changes or bug corrections. After this one, all future updates will be linked to security and are only available for users who have extended their Windows 10 support via the ESU program. (The ESU program is only opt. If you do not do, you will stop receiving updates on your Windows 10 PC, which opens up at risk.)
