Microsoft has officially acknowledged a significant disruption affecting Windows 11 version 24H2<\/a> users, specifically after installing the cumulative update KB5062553<\/a> released in July 2025.<\/p>\n The issue primarily affects environments using Virtual Desktop Infrastructure (VDI) and devices undergoing their first user logon.<\/p>\n Reports indicate that essential shell components, including the Start Menu, Taskbar<\/a>, and System Settings, are failing to initialize correctly, leaving users with a severely degraded or unusable desktop experience.<\/p>\n The disruption stems from the operating system\u2019s inability to register specific dependency packages in time during the logon process. This behavior is particularly acute in non-persistent OS installations where application packages must be provisioned fresh for each user session.<\/p>\n Administrators managing virtual environments have reported that users are frequently greeted with empty taskbars, unresponsive Start buttons, or immediate crashes of the explorer.exe process upon signing in.<\/p>\n The problem is not limited to VDI; standard physical workstations can also exhibit these symptoms during the initial user profile creation immediately following the update application.<\/p>\n The root cause has been identified as a race condition involving XAML (Extensible Application Markup Language) components. These components are critical for rendering the modern Windows UI.<\/p>\n When the update is applied, the dependent packages required by the shell do not register before the shell attempts to load them. This results in silent failures or explicit error messages from processes such as StartMenuExperienceHost.exe and ShellHost.exe.<\/p>\n The following table details the specific components and packages involved in this failure:<\/p>\n
