Find and Change Settings

Setting Where to find How to change
Screen Magnifier Notifications and Voice Prompts Settings > Accessibility > Magnifier Open Settings > Accessibility > Magnifier and turn Magnifier on or off. Voice prompts for zoom, mode switch, color inversion, and on/off actions are now integrated with Narrator. To adjust these, ensure Narrator is enabled under Settings > Accessibility > Narrator.
Screen Magnifier Protected Content Settings > Accessibility > Magnifier To allow magnification of protected content, go to Settings > Accessibility > Magnifier and enable the option to magnify content with permissions if available. The magnifier movement smoothness in Lens mode is applied automatically.
Task Manager NPU and Isolation Columns Task Manager > Processes / Users / Details / Performance tabs Open Task Manager. Right-click any column header on the Processes, Users, or Details tab and select NPU, NPU Engine, NPU Dedicated Memory, NPU Shared Memory, or Isolation to add them. The Performance tab now shows neural engines within GPUs automatically.
Multi-App Camera Settings > Bluetooth & devices > Cameras To allow multiple apps to use the camera stream simultaneously, go to Settings > Bluetooth & devices > Cameras and enable Multi-App Camera. Basic Camera mode can be enabled under the same camera settings for troubleshooting. Administrators can configure these via group policy under Computer Configuration > Administrative Templates > Windows Components > Camera > Configure camera settings.
Windows Setup Custom User Folder Name Windows Setup > Device Name page During clean Windows setup, on the Device Name page, you can specify a custom user folder name in the provided field. This option is only available during setup. If you skip this step, a default folder name is generated based on standard naming rules.
Accent Color Matching Settings > Personalization > Colors Go to Settings > Personalization > Colors and enable Automatically pick an accent color from my background. The accent color accuracy has been improved. Wallpaper preservation reliability is applied automatically across reboots and updates.
Windows Hello Default Sign-in Method Settings > Accounts > Sign-in options If Windows Hello face or fingerprint is configured under Settings > Accounts > Sign-in options, it becomes the default sign-in method automatically. To keep using a PIN instead, enter the PIN manually three consecutive times at login, and the system will stay on PIN until you switch methods manually.
Windows Search Box File Search Search box on the taskbar Click the search box on the taskbar and type at least two characters. Search now finds and prioritizes files matching those characters automatically. No additional configuration is required.
Dev Drive Size in Gigabytes Settings > System > Storage > Advanced storage settings > Disks & volumes When creating a Dev Drive or resizing a volume, open Settings > System > Storage > Advanced storage settings > Disks & volumes. The size dialog now accepts gigabytes. The UAC prompt appears only when navigating to view temporary files within this section.
