Today Microsoft has released the non-security optional preview update for Windows 11, also known as the C release, for the month of October 2025 on version 23H2. The new update under KB5067112 (build 22621.6133) brings some changes to the intial setup or the OOBE (out of box experience) which may or may not be desirable to you. The company is adding a "Personalized Offers" to entice you with ads for other Microsoft products and services.
Aside from that, the update brings some bug fixes and improvements. The full changelog is given below:
Here is the main highlight of the update:
- This non-security update includes quality improvements.
Improvements on the Normal rollout are as follows:
- [Input] Fixed: This update addresses an issue where the touch keyboard does not enter characters into text fields after the device wakes from sleep. Although touch keyboard animations appear correctly, key presses do not register—for example, when entering a password on the sign-in screen.
- [Networking] Fixed: An issue where external virtual switches lose their physical network interface card (NIC) bindings and convert to internal switches when the host restarts, resulting in network connectivity loss. The issue was caused by incorrect detection of orphaned virtual switch objects during Host Network Service startup.
- [Shell] This update enables the Personalized Offers feature during device setup in the Out-of-Box Experience (OOBE), and in Settings after the user reaches the desktop.
- [Storage] Fixed: This update addresses an issue that affects disk communication and causes connectivity errors during Azure Stack Hub or Azure Local cluster upgrades.
