Microsoft is set to roll out its December security update for Windows 11 today. This final Patch Tuesday of 2025 promises to be substantial, featuring at least 16 enhancements as reported by Windows Central.
The updates encompass aesthetic tweaks to core components like the Start menu, refinements to current capabilities, and fresh additions. Here's an overview of these developments.
The search bar in Windows has undergone a visual refresh, aligning its dimensions with the updated Start menu for better harmony. That said, the expansive coverage of the Start menu on user screens persists as an unresolved issue, with future adjustments uncertain.
Integration of Microsoft's Copilot AI expands to the taskbar, introducing a 'Share with Copilot' feature. This will display a preview of the active application, enabling seamless chats through Copilot Vision. Hovering over taskbar icons will also yield fluid switches between programs.
Enhancements are coming to Windows Spotlight, which rotates desktop wallpapers dynamically. Users can now access quick background swaps via right-click on the desktop, plus an 'Explore background' choice that delivers details on the image.
Easier toggling off of Drag Tray is now available, a tool that lets files be dragged upward for instant sharing prompts. Previously irksome for some, it can now be disabled in Settings under System and Nearby sharing.
Dark theme supporters will appreciate the refined File Explorer dark mode, which applies a cohesive style to dialog boxes for tasks like file transfers. Progress dialogs and similar interfaces are adapting too, though occasional mismatches or startup flashes may linger as Microsoft iterates further.
Device specs are more accessible without menu navigation, thanks to a fresh 'Device information' section on the Settings homepage. It covers details on the CPU, storage, RAM, and GPU, among others.
The Settings app now includes a dedicated mobile device management interface, allowing addition of gadgets, configuration of linked phones or tablets, and account-based removal.
The system information display gets a makeover this month, limited to a preview of the wallpaper and a PC renaming tool. Certain areas will see title updates or expanded content.
The Advanced settings area gains a 'Virtual Workspaces' subsection for handling virtual tools like Windows Sandbox and secure environments.
Post-update, keyboard-related choices appear in Settings via Bluetooth and devices > Keyboard, including adjustments for repeat speed, Copilot key remapping, and input aids.
Since its September debut, Quick Machine Recovery has enabled swift Windows 11 fixes. This patch refines its setup to run diagnostics once only, avoiding endless cycles and focusing on precise resolutions.
A revamped widgets panel arrives on Tuesday, boasting uniform styling. It distinguishes widgets from the Discover feed without overlays, and alerts include source panel icons.
Touch-enabled Windows 11 hardware now supports pen-based vibrations for tactile responses during actions, such as window closures.
On Copilot-equipped machines, a 'Click to execute' right-click menu organizes commands like opening, saving, duplicating, or distributing files. A dedicated field speeds up Copilot interactions too.
Xbox's immersive Full Screen Mode extends beyond Asus ROG Ally and Ally X to standard PCs, mimicking a console interface for simpler controller use and lighter desktop overhead—potentially freeing up to 2GB RAM.
To enable it, navigate to Settings > Gaming > Full screen experience, then reboot for activation.
Copilot PC owners can apply Windows Studio Effects' AI camera tools to extra sources, like external webcams or built-in secondary lenses.
Beyond these additions, the December update tackles bugs and vulnerabilities, with dedicated coverage forthcoming in another piece.
