Introduction

Windows 10, Microsoft's resilient yet aging operating system, is nearing the end of its lifecycle. Despite this, Microsoft continues to roll out updates that sometimes introduce unexpected issues. One such recent incident, following the April update, has caused widespread disruption among power users: the disappearance of Jump Lists from the Start menu.

Jump Lists have long been a productivity staple in Windows 10, allowing quick access to recently or frequently used files and tasks directly from the taskbar or Start menu. Their sudden absence following the update has prompted numerous complaints, technical discussions, and a hunt for solutions.

What are Jump Lists?

Jump Lists are context menus attached to taskbar icons and Start menu pinned apps that provide shortcuts to recently opened files, frequent tasks, or pinned items associated with that specific application. Introduced in Windows 7 and continued through Windows 10, these lists accelerate workflow by cutting down navigation steps, making work smoother for both casual and power users.

Background on the Issue

The April update for Windows 10 — identified as KB5055518 — has introduced a critical bug removing Jump Lists from the Start menu for many users, especially those on Windows 10 versions approaching end-of-support phases. Unlike outright removing features, this disappearance appears as an unintended side effect, disrupting what was considered a fundamental Windows feature.

Affected users report:

  • Jump Lists missing from taskbar and Start menu pinned apps.
  • Inability to quickly access recent or pinned documents from the Start interface.
  • Some users experience the issue intermittently, while others face complete Jump Lists removal.

Microsoft has not officially addressed the bug publicly, which has increased frustration among the community.

Causes of the Jump Lists Disappearance

Several theories and technical analyses indicate:

  1. Update-induced Bug: The KB5055518 cumulative update seems to have unintended side effects due to code changes affecting Start menu data caching and display.
  2. Legacy Feature Deprecation: Windows 10 is in its sunset phase, with Microsoft shifting focus toward Windows 11. This shift might have led to less thorough testing of legacy features like Jump Lists.
  3. Corrupted User Data: In some cases, user profile data related to Jump Lists caching becomes corrupted due to update processes, causing their nonappearance.

Workarounds and Fixes

While a full fix awaits Microsoft's patch, the community and IT experts have proposed several temporary solutions:

1. Restart Explorer.exe

  • Open Task Manager.
  • Find "Windows Explorer" in the processes.
  • Right-click > Restart.

A quick restart can refresh the Start menu and taskbar elements, sometimes restoring Jump Lists.

2. Clear Jump Lists Cache Manually

  • Navigate to INLINECODE0 .
  • Delete the files to clear Jump Lists cache.

Restart your PC afterward.

3. Toggle Jump Lists Settings

  • Go to Settings > Personalization > Start.
  • Turn off "Show recently opened items in Jump Lists on Start or the taskbar."
  • Restart your PC.
  • Turn the setting back on.

4. Use Third-Party Tools

Some users resort to third-party utilities that restore or mimic Jump Lists functionality, but caution is advised to avoid security risks.

5. Roll Back Update

For critical workflows, uninstalling the problematic update via Windows Update history can restore Jump Lists temporarily.

Implications and Impact

The disappearance of Jump Lists impacts users by:

  • Slowing productivity for users accustomed to quick access links.
  • Increasing frustration due to lack of official solutions.
  • Driving some users to consider upgrading prematurely to Windows 11 or alternative workflows.

For enterprises, especially those with slow update cycles or legacy systems, this bug underscores challenges with forced updates and legacy feature support.

Technical Details

  • Jump Lists are stored in the file system under INLINECODE1 and INLINECODE2 folders.
  • The update affects the indexing and caching services responsible for rendering these lists.
  • The Start menu shell experience host may fail to retrieve or render Jump Lists data post-update.

Conclusion

While Windows 10 continues to serve millions, this April update’s disruption of Jump Lists exemplifies the complexities and risks in maintaining legacy OS features amid ongoing development and migration efforts. Workarounds exist, but users and IT support teams must stay vigilant for official patches or consider migration plans to Windows 11 to avoid future pitfalls.
