The update KB5031455 bumps the version number to build 22621.2500 and, according to the official changes, introduces a new gleam icon for the search box that opens the Bing search engine in the browser, showcasing daily search highlights.

Also, on October 23, the company updated the original announcement to include the rollout of digital handwriting (inking) in the United States market that allows writing with a digital pen on edit boxes with improved recognition technology.

Finally, the Settings app now includes a new “System Components” page in the “System” section that moves those applications and extensions that are considered essential for the operating system from the “Installed Apps” page.

  • Affects the search highlight gleam in the search box. When you select the gleam, a page will appear for the daily search highlight. This is available to a small audience initially and deploys more broadly in the months that follow.

  • Supports the currency change in Croatia from the Kuna to the Euro.

  • Fixes a memory leak in ctfmon.exe.
  • Fixes a memory leak in TextInputHost.exe.
  • Fixes an issue that affects touchscreens. They do not work properly when you use more than one display.
  • Fixes an issue that affects Dynamic Lighting. The default provider is not applied as expected. This occurs when you set it up using Unattend files.
  • Fixes an issue that affects the Microsoft Store. It stops responding when you access it from Windows Mixed Reality.
  • Fixes an issue that affects cellular settings. The name of the mobile operator is wrong.
  • Fixes an issue that affects the Windows Firewall Profile. When you are on a domain-authenticated network, it detects a public domain. This is wrong.
  • Fixes an issue that occurs when you use Universal Print to add a printer using its location. When you browse the tree view structure, the tree nodes do not work as you expect.
  • Fixes an issue that affects Outlook. It stops responding. This occurs when you print to an Internet Printing Protocol (IPP) printer that has a slow response time.
  • Fixes an error that occurs when you print using v4 print drivers.

  • Fixes an issue that blocks external connections. This occurs when you set up a Kubernetes load-balanced service and turn on session affinity.
  • Fixes a Firewall configuration service provider (CSP) issue. It stops a device from syncing.
  • Fixes an issue that affects devices on which you have defined Windows Information Protection (WIP) policies and set up a proxy. A stop error occurs. This happens on devices that use Microsoft Defender Application Guard. In the past, WIP was known as enterprise data protection (EDP).
  • Fixes an issue that occurs after you run a Push-button reset. You cannot set up Windows Hello facial recognition. This affects devices that have Windows Enhanced Sign-in Security (ESS) turned on.
  • Fixes an issue that affects PowerShell versions greater than 7.3.1. It might block scripts and not let them run in Constrained Language Mode. This occurs when you turn on a WDAC policy.
  • Fixes an issue that affects the Automatically Hide the Taskbar setting. You cannot set it using the SHAppBarMessage() API.
