Insider KB5089574 Windows 11 Insider Beta (25H2) build 26220.8544 - May 29



 Windows Insider Blog:

[Updated 6/01: Removal of solid spinners from this builds release notes, we look forward to bringing the feature to the Beta build in the near future.]

Changes and improvements

[Windows design]

  • We are introducing consistent solid (donut) spinners across key Windows scenarios including Boot, Logon, Restart, Shutdown, and Update. This update replaces legacy spinner visuals to deliver a more cohesive and modern experience aligned with Windows design standards. Users will now see a unified spinner behavior with corresponding status text (e.g., "Restarting", "Working on updates", "Welcome") across these flows, improving perceived reliability and visual consistency.

[Search]​

  • Search by Substring: Files with compound names or content (e.g., MeetingNotesApril, ProjectStatusReport) are now easily discoverable by typing “april” or “status”.

[Windows Ready Print]​

  • Last month, we introduced a change where new printer installations use IPP by default when supported to simplify setup and improve reliability (see our third-party driver deprecation timeline: End of Servicing Plan for Third-Party Printer Drivers on Windows). This month, we're adding a new toggle in Settings > Bluetooth & devices > Printers & scanners > Default install printers using Windows Ready Print to give you control over this behavior.

  • When enabled, Windows installs supported printers using IPP by default. When turned off, Windows may use other available installation methods.
  • This experience is part of our modern print platform, now called Windows Ready Print, designed to deliver a more consistent, reliable, and simplified printing experience.

Reminders for Windows Insiders in the Beta Channel

  • Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.8544).
  • The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
  • Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they're ready.
  • Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
  • Check out Flight Hub for a complete look at what build is in which Insider channel.

Installed on two machines with three reboots each, clean DISM/SFC scans. One machine took a long time to load the desktop but eventually did.

Updated fine for me on two computers. Interestingly, on both computers it made me re-enter/setup a PIN password again.
