Find and Change Settings

Setting Where to find How to change
Start menu: Recent section rename Settings > Personalization > Start The Recommended section is now renamed to Recent. This change is automatic; no manual toggle is required. You can manage its visibility using the new section-level toggles on the same settings page.
Start menu: Section-level toggles (Pinned, Recent, All apps) Settings > Personalization > Start Open Settings > Personalization > Start. Use the new independent toggles to show or hide the Pinned, Recent, and All apps sections according to your preference.
Start menu: Small or large layout size Settings > Personalization > Start > Layout Go to Settings > Personalization > Start and find the Layout option. Choose either Small or Large to override the Automatic default size and apply your preferred Start menu dimensions.
Start menu: Hide name and profile picture Settings > Personalization > Start Navigate to Settings > Personalization > Start and enable the option to hide your account name and profile picture from the Start menu. Disable it to show them again.
Search: Substring matching for files Start menu search or Search bar on taskbar No setting change is required. Simply type a partial word from inside a file name or content (e.g., "April" for "MeetingNotesApril") into the search box, and the improved substring search will return matching results automatically.
Taskbar: Swipe gesture on alternative positions Taskbar (when positioned left, right, or top) When the taskbar is placed on the left, right, or top edge of the screen, use a swipe-in touch gesture from that edge to invoke the taskbar. This works automatically; no additional configuration is needed.
Reset PC: Cloud download workaround Settings > System > Recovery > Reset this PC If a local reset hangs, choose the "Cloud download" option instead of "Local reinstall" when prompted. This issue is resolved in the current update; installing it permanently fixes the problem.
