What’s new on Windows 11 build 26300.8553 (Experimental)
These are the new features and improvements rolling out in the Experimental Channel:
Start menu resize option
Microsoft is adding new size options for the Start menu on Windows 11, allowing users to choose between “Small,” “Large,” and “Automatic” layouts. The new settings make it easier to customize how much content appears on screen.

Build 26300.8553 also renames the “Recommended” section to “Recent” across the Start menu and Settings app. In addition, users can now independently show or hide the “Pinned,” “Recent,” and “All” sections.

Other changes include the option to hide the account name and profile picture in Start, and a redesigned Settings page with new customization controls.

Windows Search changes
Windows Search now supports substring matching, making it easier to find files with compound names or text content. For example, users can now type parts of a word, such as “april” or “status,” to locate files such as “MeetingNotesApril” or “ProjectStatusReport.”
This improvement is available in builds 26300.8553 and 26220.8544.
Taskbar improvements
Microsoft is also improving the taskbar experience when using alternate Taskbar positions. This update fixes several visual issues and adds support for touch swipe gestures to reveal the Taskbar in those layouts.
Known issues
As part of the known issues, Microsoft warns that the Reset this PC feature may get stuck during the reset process in build 26300.8553.
What’s new on Windows 11 build 26220.8544 (Beta)
These are the new features and improvements rolling out in the Beta channel:
Windows Ready Print adds new install toggle
On build 26220.8544 for the Beta channel, the development team is adding a new Windows Ready Print setting to control how new printers are installed on the system.
The new option appears under Settings > Bluetooth & devices > Printers & scanners > Default install printers using Windows Ready Print. When enabled, the operating system installs compatible printers by default, using the IPP (Internet Printing Protocol) standard to improve reliability and simplify setup.

If the setting is turned off, the system can use other available installation methods instead.
The feature is part of Microsoft’s modern printing platform initiative, now branded as Windows Ready Print, which aims to deliver a more consistent and streamlined printing experience while moving away from legacy third-party printer drivers.
Consistent new spinners across core experiences
Windows 11 build 26220.8544 is also rolling out a unified “donut” style spinner design across key Windows 11 system flows, including Boot, Logon, Restart, Shutdown, and Windows Update. The change replaces legacy loading indicators with a modern, consistent visual language aligned with the current Windows 11 design language.

Alongside the new spinner style, users will see updated status text such as “Restarting,” “Working on updates,” and “Welcome,” depending on the system state. The goal is to improve visual consistency across core experiences and enhance perceived reliability during system transitions.
