This security update contains fixes and quality improvements from KB5067036 (released October 28, 2025). The following summary outlines key issues addressed by this update. Also, included are available new features. The bold text within the brackets indicates the item or area of the change.
[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
