Windows 10 update KB5025221

These are the fixes and improvements coming to the next update of Windows 10:

  • This update implements the new Windows Local Administrator Password Solution (LAPS) as a Windows inbox feature.
  • This update affects the Arab Republic of Egypt. The update supports the government’s daylight saving time change order for 2023.
  • This update addresses a compatibility issue. The issue occurs because of unsupported use of the registry.
  • Addresses a known issue that affects kiosk device profiles.
  • This update affects the ms-appinstaller URI. It now works with the DesktopAppInstaller policy.
  • Addresses an issue that affects the Remote Procedure Call Service (rpcss.exe). The issue might cause a race condition between the Distributed Component Object Model (DCOM) and the Microsoft Remote Procedure Call (RPC) endpoint mapper.
  • Addresses an issue that affects the Microsoft HTML Application Host (HTA). This issue blocks code execution that uses Microsoft HTA. This occurs when you turn on Windows Defender Application Control (WDAC) User Mode Code Integrity (UMCI) enforced mode.
  • Addresses an issue that affects Desired State Configuration. It loses its previously configured options. This occurs if metaconfig.mof is missing.
  • Addresses compatibility issues that affect some printers. These printers use Windows Graphical Device Interface (GDI) printer drivers. These drivers do not completely adhere to GDI specifications.
  • Addresses an issue that affects the Simple Certificate Enrollment Protocol (SCEP) certificate. The system reports some SCEP certificate installations as failed. Instead, the system should report them as pending.
  • Addresses an issue that affects USB printers. The system classifies them as multimedia devices even though they are not.
  • Addresses an issue that affects the Fast Identity Online 2.0 (FIDO2) PIN credential icon. It does not appear on the credentials screen of an external monitor. This occurs when that monitor is attached to a closed laptop.
  • This update affects applications that use the Windows UI Library in the Windows App SDK (WinUI 3). It makes printing for them possible on Windows 10 devices.
  • Addresses an issue that affects the SharedPC account manager. It cannot delete multiple accounts during cleanup.
  • Addresses an issue that might affect lsass.exe. It might stop responding. This occurs when it sends a Lightweight Directory Access Protocol (LDAP) query to a domain controller that has a very large LDAP filter.
