I forced Windows 11’s CPU boost on a 10-year-old PC, and it feels surprisingly new

Windows 11 has introduced the Low Latency Profile to enhance the responsiveness of the Start menu, Search, and Action Center by rapidly increasing CPU frequency during user interactions. Testing on a Lenovo ThinkCentre M700 Mini Desktop with a 6th Generation Intel Core i3-6100 processor showed that the Low Latency Profile could be activated via the June 2026 Patch Tuesday update (KB5094126) and the third-party tool ViVeTool. Initially, no significant CPU frequency spike was observed, but after enabling the feature, the CPU frequency increased from approximately 800MHz to 3.0GHz and then to 3.7GHz almost instantaneously during interactions. This resulted in a marked improvement in the responsiveness of the Start menu and Action Center, with the latter showing the most significant enhancement. The Low Latency Profile effectively improved performance on older systems without adverse effects on battery life or thermal output.

Microsoft is bringing 10 new features to Windows 11’s taskbar and Start menu

Microsoft is planning to introduce several new features and improvements to the Windows 11 taskbar and Start menu in response to user feedback. Users will soon have the ability to reposition the taskbar to the top, left, or right of the screen, with options for icon alignment. A new “Show smaller taskbar buttons” toggle will reduce the physical height of the taskbar, providing more screen space. These features are currently available in the Insider Experimental channel and are expected to roll out to all PCs soon. The Widgets board will also see changes, with the MSN feed being disabled by default and the “Open on hover” behavior eliminated. In the Start menu, users will gain section-level toggles to hide or show the Pinned, Recent, and All Apps sections. The Start menu can be resized to either Small or Large, and a new privacy mode will hide account names and profile pictures. The “Recommended” section will be renamed to “Recent,” and improvements will be made to file relevancy. Additionally, the Start menu will transition to a new modular engine, enhancing responsiveness and addressing previous criticisms regarding performance.

Microsoft wants AI to customize your Windows 11 entirely with one sentence, shows off a demo

At Build 2026, Microsoft announced plans to enhance Windows 11 personalization through AI agents, with API endpoints available for developers to create tailored experiences. Product Manager Samantha Song highlighted the need for a more user-friendly interface that reflects individual preferences, noting current customization options can be cumbersome. Microsoft introduced "WinUI skills," enabling developers to use AI agents like Copilot to create native applications that interact with Windows APIs. Users could instruct AI to modify themes, such as creating a cherry blossom theme, which would adjust wallpapers and accent colors automatically. AI skills could also apply accent colors to File Explorer and download themed wallpapers. The theme module can orchestrate multiple actions, allowing users to change their entire Windows theme with a single command. Microsoft is exploring a themes agent for generating new themes. While currently an open-source project, there is potential for these features to be integrated into Windows 11, enhancing user experience through personalized customization.
