Fix: Windows Update KB4579311 causing Explorer to Crash repeatedly when Logging In

The Explorer of your system may crash if conflicting applications (like Halo Master Chief Collection) are hindering the operation of the Explorer. Moreover, the corrupt user profile of your system may also cause the error under discussion. The user encounters the issue (after the Windows update) when he tries to log in to the system but the Explorer crashes (or the Start bar flickers on or off and the desktop is black) repeatedly and then eventually lets the user in.

Before moving on with the solutions, keep in mind that you may have to try these solutions in the safe mode if you cannot use the system due to the Explorer crashing. Although some users reported that waiting for 6 to 10 minutes after booting the system in the normal mode, the system started to behave normally.

Solution 1: Update the Windows of Your System to the Latest Build

Microsoft regularly updates Windows to add new features and patch known bugs like the one causing the Explorer issue. In this scenario, updating the Windows of your computer to the latest release may solve the problem.

  1. Manually update the Windows version of your system to the latest release of Windows OS. Make sure no optional/additional updates are pending.
  2. Then check if the Explorer issue is resolved.

Solution 2: Remove the Conflicting Applications

In a Windows environment, applications/system modules co-exist and share the system resources. The Explorer may crash if any of the installed applications on your system are hindering the Explorer operation. In this scenario, removing the conflicting applications may solve the problem. One such application known to create the issue is Halo Master Chief Collection.

  1. Press the Windows key and open Settings. Then select Apps and expand Halo Master Chief Collection.
    Open Apps in the Windows Settings
  2. Now click on the Uninstall button and then confirm to uninstall the Halo Master Chief Collection.
    Uninstall Halo Master Chief Collection
  3. Now repeat the same to uninstall any other conflicting applications and then reboot your PC.
  4. Upon reboot, check if the Explorer issue is resolved.

Solution 3: Uninstall the Buggy Update

Microsoft has a known history of releasing buggy updates and the issue at hand could also be a result of a buggy update. In this context, uninstalling the buggy update may solve the problem.

  1. Press the Windows key and open Settings. Now select Update & Security and open View Update History (in the right pane of the window).
    View Update History of Your System
  2. Then click on Uninstall Updates and then select the problematic update (in this case, KB4569311).
    Open Uninstall Updates
  3. Now click on the Uninstall button and then proceed with the screen prompts to uninstall the update.
  4. Then check if the Explorer issue is resolved. If so, then you may have to pause or block the update (i.e., KB4569311) from installing.

If you could not uninstall the update by using the above method (due to the crashing of Explorer), then try the following steps:

  1. Restart your PC while holding the Shift key and then select Troubleshoot.
    Open Troubleshoot in Advanced Startup Menu
  2. Now open Advanced Options and choose Uninstall Updates.
    Open Advanced Options in the Startup Menu
  3. Then select the problematic update (i.e., KB4569311) or the latest quality update and wait for the completion of the process.
    Uninstall Updates in the Advanced Options
  4. Now check if the Explorer issue is resolved.

Solution 4: Disable Storage and Connected Devices Platform User Services of Your System

You may encounter the Explorer error if the Storage and Connected Devices Platform User Services of your system is hindering its operation. In this case, disabling the Storage and Connected Devices Platform User Services may solve the problem.

  1. Launch the Windows menu by pressing the Windows key and search for Services. Then, in the results pulled by the search, right-click on Services, and in the sub-menu, choose Run as Administrator.
    Open Services as Administrator
  2. Now, right-click on the Storage service and choose Properties.
    Open Properties of the Storage Service
  3. Then expand the dropdown of Startup and select Disabled.
    Change the Startup Type of the Storage Service to Disabled
  4. Now click on the Apply/OK buttons. Then repeat the same for Connected Devices Platform User Service and reboot your system.
  5. Upon reboot, check if the Explorer is working fine.

If you cannot open Services (step 1 mentioned above) due to the Explorer crashing, then either boot your system into the Safe Mode or perform the following steps:

  1. Press Ctrl + Alt + Del buttons on your keyboard and open the Task Manager.
  2. Now steer to the Services tab and click on Open Services (near the bottom of the screen).
    Open Services Through the System’s Task Manager
  3. Then follow steps 2 to 6 discussed above to check if the Explorer issue is resolved. If so, then check if changing the startup type of the Storage service to manual sorts out the issue if you need access to certain Microsoft Store apps. If you are having issues with the Microsoft Store Apps after disabling the above-said services, then you may have to create a task in the Task Scheduler that enables the services when the user logins the system and disables them when the user logoffs the system.

Solution 5: Create Another User Account

The Explorer may crash if the user account of your system is corrupt. In this case, creating another user account with administrative privileges may solve the problem.

  1. Create another user profile for your PC. Make sure the newly created account is an administrator.
  2. Now power off your PC and then power it on. Upon startup, log in using the newly created account and check if the Explorer issue is resolved.

Solution 6: Edit the System’s Registry to Remove the BannerStore Key

The explorer may crash if the stack-based buffer of your system glitches out. In this scenario, disabling the BannerStore key in the system’s registry may clear the glitch and thus solve the problem.

  1. Create a backup of the system’s registry.
  2. Click in the Windows Search bar (on the Taskbar of your system) and type Registry Editor. Then, in the results, right-click on the Registry Editor and select Run as Administrator.
    Open Registry Editor as Administrator
  3. Then navigate to the following:
  4. Now, right-click on the BannerStore key (in the left pane of the window) and Rename it (such as BannerStore_bak).
    Rename the BannerStore Key in the Registry Editor
  5. Now reboot your system after exiting the Registry Editor and hopefully, the Explorer issue is resolved.

If you cannot open the Registry Editor at step 1 (due to crashing of Explorer), follow the steps below:

  1. Press Ctrl + Alt + Del keys to launch the Task Manager of your system and open its File menu.
  2. Now select Run New Task and then type RegEdit.
    Run a New Task in the Task Manager
  3. Then check the checkbox of Create This Task with Administrative Privileges and click on the OK button.
    Run the New Task of the Registry Editor with Administrative Privileges
  4. Now repeat steps 3 to 5 discussed above and hopefully, the Explorer is clear of the error.

If the issue is still there, then either you have to Reset your PC or perform a clean install of Windows.
