Microsoft releases KB5012592 update for Windows 11 with vital security fixes and easier browser switching
Windows 11 users have an important update to install. The KB5012592 update takes the operating system up to build 22000.613 and not only includes a number of important security fixes, but also introduces several significant changes.
Like the previously released KB5011563 update, the new KB5012592 update makes it possible to display up to three high-priority toast notifications simultaneously as well as fixing issues with OneDrive. The update also introduces a simpler way to change the default web browser in Windows 11, although it is a change that has been met with disdain from like likes of Mozilla and Vivaldi.
- Vivaldi joins Mozilla in lambasting Microsoft's approach to changing Windows 11's default browser
- Microsoft won't give you any more security updates if you don't upgrade Windows 10 version 20H2 in the next month
- You might want to move the taskbar in Windows 11, but Microsoft doesn't think it is important
Microsoft does not go into any detail about the security fixes included as part of the KB5012592 update. All the company has to say on this front is that it, "updates security for your Windows operating system". However, elsewhere we learn that Microsoft's Patch Tuesday updates for April address 117 CVEs (108 important and 9 critical), including CVE-2022-24521.
The changelog from the preview version of the update that was released last month still applies to the KB5012592 update:
- New! Displays up to three high-priority toast notifications simultaneously. This feature is for apps that send notifications for calls, reminders, or alarms using Windows notifications in the OS. As a result, up to four toast notifications might appear simultaneously–three high-priority notifications and one normal priority notification.
- Addresses an issue that turns off auto-startup for Universal Windows Platform (UWP) apps after you upgrade the OS.
- Addresses an issue that causes SystemSettings.exe to stop working.
- Addresses an issue that affects searchindexer.exe and prevents Microsoft Outlook’s offline search from returning recent emails.
- Addresses an issue that increases the startup time for Windows. This issue occurs because a UI thread in a networking API stops responding when a 5G wireless wide area network (WWAN) device is slow to wake up.
- Addresses a memory leak in the wmipicmp.dll module that causes a lot of false alarms in the System Center Operations Manager (SCOM) datacenter monitoring system.
- Addresses an issue that incorrectly returns the Execution Policy settings from the registry.
- Addresses an issue in which modern browsers fail to correctly render HTML that is generated by gpresult/h.
- Addresses an issue that causes an "Access denied" exception for a file during a PowerShell test for AppLocker.
- Addresses an issue that causes the Remote Desktop Service (RDS)server to become unstable when the number of signed in users exceeds 100. This prevents you from accessing published applications using RDS on Windows Server 2019.
- Addresses an issue that returns an error message when you browse for a domain or organizational unit (OU). This issue occurs because of improper zeroing out of memory.
- Addresses an issue that causes the Group Policy Management Console to stop working after you close it. The system logs Application Error Event ID 1000 and the error, 0xc0000005 (STATUS_ACCESS_VIOLATION); the failing module is GPOAdmin.dll.
- Addresses an issue that might cause the Group Policy Service to stop processing telemetry information for Group Policy Registry Preferences.
- Addresses a stop error (0xD1, DRIVER_IRQL_NOT_LESS_OR_EQUAL) in the DirectX kernel component.
- Addresses an issue that might cause Kerberos.dll to stop working within the Local Security Authority Subsystem Service (LSASS). This occurs when LSASS processes simultaneous Service for User (S4U) user-to-user (U2U) requests for the same client user.
- Addresses an issue that affects the Key Distribution Center (KDC) Proxy. The KDC Proxy cannot properly obtain Kerberos tickets for signing in to Key Trust Windows Hello for Business.
- Adds support for Microsoft Account (MSA) Pass-through scenarios in Azure Active Directory(AAD) Web Account Manager (WAM).
- Addresses an issue that logs Event ID 37 during certain password change scenarios, including failover cluster name object (CNO) or virtual computer object (VCO) password changes.
- Addresses an issue that prevents the User Account Control (UAC) dialog from correctly showing the application that is requesting elevated privileges.
- Addresses an issue that might cause a Microsoft OneDrive file to lose focus after you rename it and press the Enter key.

- Addresses an issue that causes stop error 0x1E in the SMB Server (srv2.sys).
