Microsoft Addresses Windows 11 Explorer Crash and Taskbar Disappearance Issues

A critical issue affecting Windows 11 has led to unexpected crashes of Explorer.exe, causing significant disruptions in user experience. This bug can result in the disappearance of the desktop user interface, including the taskbar and Start menu. Microsoft has acknowledged this problem and is addressing it in the optional update, Windows 11 KB5074105, scheduled for January 2026.

Windows 11 Explorer Crash and Taskbar Issues

The instability occurs when Explorer.exe, which is vital for the Windows shell, ceases to respond. If Explorer becomes unresponsive, users are unable to access essential features like the taskbar and Start menu without manually restarting the program via Task Manager.

Impact of Startup Apps

This specific bug primarily affects systems with certain startup applications configured. Microsoft noted, “This update addresses an issue where Explorer.exe might stop responding the first time you sign in to your PC if certain apps were configured as startup apps.” Consequently, this can lead to the taskbar failing to appear.

  • Symptoms: Taskbar and desktop may disappear.
  • Recommended Action: Install the optional update KB5074105.

What’s Included in the Update

The January 2026 optional update promises several improvements, including:

  • Restoration of custom folder names by addressing the LocalizedResourceName entry issue.
  • Resolution of slow or unresponsive File Explorer elements.
  • Fixes for an unresponsive lock screen.
  • Solutions for black screen issues connected to specific Windows updates.

Previous updates, particularly KB5074109, have caused several user complaints, including the black screen issue. Microsoft has since clarified that these problems are not related to Nvidia drivers but are linked to their system updates.

Future Considerations and Updates

Microsoft is gradually rolling out the KB5074105 patch, meaning it may take time for all users to receive it. Users currently running Build 26200.7623 or newer are eligible for this patch. It is advisable for anyone experiencing Explorer.exe-related issues to seek this update promptly.
