[Screen capture] Fixed: The Capture Service and Snipping Tool stop responding. This occurs when you press Windows logo key+Shift+S several times while Narrator is on.
[Chinese Pinyin input method editor (IME)] Bing will stop giving automatic suggestions in the search box for search engine sites, like Baidu. To get manual suggestions, use Ctrl+Tab or the chevron button (>).

[USB audio device drivers] Fixed: The code 10 error message, “This device cannot start” appears. This occurs when you connect to certain external audio management devices.
[USB cameras] Fixed: Your device does not recognize the camera is on. This issue occurs after you install the January 2025 security update.
