Simplified Windows update titles
A new, standardized title format makes Windows updates easier to read and understand. It improves clarity by removing unnecessary technical elements like platform architecture. Key identifiers such as date prefixes, the KB number, and build or version are retained to help you quickly recognize each update.
For more details, see Simplified Windows Update titles or its accompanying blog post.
December servicing update schedule
Due to reduced operations during the Western holidays in December and New Year's Day, Microsoft will not release a non-security preview update in December 2025. The monthly security update will still be available as scheduled. Regular monthly servicing, including both security updates and non-security preview updates, will resume in January 2026.
Windows Secure Boot certificate expiration
Important: Secure Boot certificates used by most Windows devices are set to expire starting in June 2026. This might affect the ability of certain personal and business devices to boot securely if not updated in time. To avoid disruption, we recommend reviewing the guidance and taking action to update certificates in advance. For details and preparation steps, see Windows Secure Boot certificate expiration and CA updates.

-
[Gaming]
-
Fixed: This update addresses an issue that affects gaming handheld devices. These devices were unable to stay in low-power states, which caused faster battery drain.
-
Fixed: This update addresses an issue on some handheld gaming devices where after signing in using the built-in Gamepad, the controller might not respond in apps for about five seconds, causing a delay. After you submit your password or PIN, the touch keyboard on the sign-in screen hides automatically.​​​​​​​
-
-
[Storage] Fixed: This update addresses an issue that could cause some Storage Spaces to become inaccessible or Storage Spaces Direct to fail when creating a storage cluster.
-
​​​​​​​​​​​​​​[System utilities (known issue)] Fixed: This update addresses an issue where closing Task Manager with the Close button didn’t fully end the process, leaving background instances that could slow performance over time.  This might occur after installing KB5067036.
-
[Voice Access] Fixed: This update addresses an issue where Voice Access failed during initial setup if no microphone was connected and the voice model wasn’t installed.
-
[Window management] Fixed: This update addresses an issue where selecting the desktop could unexpectedly open Task View.
-
​​​​​​​[Networking] Fixed: This update fixes an issue in the HTTP.sys request parser, a Windows component that reads and processes HTTP requests. The parser allowed a single line break within HTTP/1.1 chunk extensions, where the RFC 9112 standard requires a carriage return and line feed (CRLF) sequence to terminate each chunk. This can cause a parsing discrepancy when front end proxies are a part of the setup. To turn off strict parsing, use the following registry key:
Registry Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Http\Parameters]
Registry value: "HttpAllowLenientChunkExtParsing"=dword:00000001
Data to be set: 1
If you've already installed previous updates, your device will download and install only the new updates included in this package.
