Does Explorer crash and restart when you open a folder window or right-click a file or folder? This post tells you how to troubleshoot Explorer crashes which sometimes seriously affect our workflow.<\/p>\n

When the Explorer shell crashes, the taskbar vanishes, and the desktop remains blank for a moment while the shell restarts itself. In a clean installation of Windows, this problem doesn’t usually occur; but if it happens, a 3rd party module or driver is probably at fault on most occasions.<\/p>\n

Please follow this essential troubleshooting checklist, and you should be able to narrow down the root cause.<\/p>\n

  1. View Reliability History<\/a><\/li>\n
  2. Disable 3rd party shell extensions<\/a><\/li>\n

  4. Clean Boot Windows Using Autoruns<\/a><\/li>\n
  5. Create a New User Account (to test)<\/a><\/li>\n

    Explorer.exe Crash Troubleshooting Tips<\/h2>\n

    <\/a>View Reliability History<\/h3>\n

    When the shell crashes, it records the reason for the crash in the Application event log, which you can see in the Event Viewer (eventvwr.msc<\/code>), or in the Reliability history in the Control Panel.<\/p>\n

    Click Start and type reliability<\/code>. Click View Reliability History<\/b> in the search results. In the Reliability Monitor window, look for Windows Explorer entries marked as Critical, showing up with the red icons and white X. Pick the relevant entry by matching the date\/time of the last Explorer crash.<\/p>\n

    <\/p>\n

    Click Check for a solution. If you’re lucky, you might get some recommendations there. If it says “No new solutions found,” double-click an entry to see if a faulting module (3rd party) is mentioned.<\/p>\n

    <\/p>\n

    Here’s another sample entry which mentions the core OS module named shcore.dll<\/code> as the fault module name.<\/p>\n

    Faulting Application Path: C:\\Windows\\explorer.exe<\/p>\n

    Problem signature\nProblem Event Name: APPCRASH\nApplication Name: explorer.exe\nApplication Version: 10.0.22000.778\nApplication Timestamp: aacb6d3d\nFault Module Name: shcore.dll\nFault Module Version: 10.0.22000.613\nFault Module Timestamp: ff7b5175\nException Code: c0000005\nException Offset: 000000000002e835\nOS Version: 10.0.22000.2.0.0.768.101\nLocale ID: 2057\nAdditional Information 1: aedd\nAdditional Information 2: aedd0082be493b9a03ea238180c8f533\nAdditional Information 3: 4d9d\nAdditional Information 4: 4d9db3365faebdf33976b36913950210\nExtra information about the problem\nBucket ID: efec0e67491262506ecc23ff01e8840a (2219188294542459914)<\/pre>\n
    Sometimes, the exact module name<\/a> (e.g., ConvertToPDFShellExtension_x64.dll) which caused the crash is mentioned. In that case, uninstalling the related software would fix the problem.<\/p>\n
    But unfortunately, in the above examples, the Fault Module Name points to ntdll.dll\/shcore.dll, core Windows modules. But the OS modules are not the culprit; the underlying cause must be found.<\/p>\n
    \n
    <\/a>Additional Tip<\/h4>\n
    Open a Command Prompt window and type:<\/p>\n
    wevtutil qe \"Application\" \/q:\"*[System[(EventID=1000)]]\" \/c:50 \/f:text \/rd:true | clip<\/pre>\n
    The above command will gather the last 50 critical events (from the “Application” event log) and save them to the clipboard. Open Notepad, paste the contents from the clipboard, and save the file. Look for the explorer.exe<\/code> entries in the file.<\/p>\n<\/div>\n
    <\/a>Disable 3rd Party Shell Extensions<\/h3>\n
    Shell Extensions are modules that attach to Explorer and load with every instance of Explorer.exe. A poorly coded 3rd party shell extension can cause Explorer to crash repeatedly.<\/p>\n
    The best way to narrow down the context menu handler (or any other type of shell extension) causing the problem is to use Nirsoft’s ShellExView. To do so, see the article Slow Right Click and Explorer Crashes Caused by Shell Extensions<\/a>.<\/p>\n
    \"troubleshoot<\/p>\n
    (Example: Here’s a case<\/a> where disabling the three NVidia Context Menu handlers fixed the issue.)<\/em><\/p>\n
    You can also use Autoruns to disable 3rd party shell extensions<\/a>, but I prefer ShellExView for this purpose.<\/em><\/p>\n
    <\/a>Control Panel Items (.CPL files)<\/h3>\n
    List out the *.cpl<\/code> files in the System32<\/code> and SysWOW64<\/code> directories. An outdated or incompatible module can cause Explorer to crash. I made a batch file to output the list of CPLs from the System32, SysWOW64 folders, and the Control Panel namespace registry keys.<\/p>\n
    The output file shows every Control Panel item registered in the system, from which 3rd party ones can be easily identified.<\/p>\n
    <\/p>\n
    [Download listallcpls.bat<\/a>]<\/b><\/p>\n
    Editor’s note:<\/b> I recently came across a case where a very old ODBC module (compiled in the year 1995) caused Explorer to crash repeatedly. It was a .CPL file in the System32 folder, placed by an old program. Deleting the .CPL file instantly fixed the issue.<\/i><\/p>\n
    If no 3rd party Control Panel items exist or eliminating them doesn’t help, move on to the next step.<\/p>\n
    <\/a>Clean Boot Windows<\/h3>\n
    Explorer loads modules added by 3rd party programs through shell extensions or DLL injection. Disable all the 3rd party modules from loading with Explorer, following the instructions in the Clean Boot<\/a> guide. Using this method, all 3rd party shell extensions, Services, and Startup Programs are disabled, and a clean instance of Explorer shell loads.<\/p>\n
    If the problem doesn’t occur in a clean boot state, the next job is to find out which one of the disabled items contributed to the crash. You may need to restart Windows multiple times to test.<\/p>\n
    For detailed information, see Clean Boot Troubleshooting Using Autoruns<\/a>. If the problem still occurs<\/u> in a clean boot state, move on to the next step.<\/p>\n
    <\/a>Create a New User Account<\/h3>\n
    Create a new user account to test if the problem occurs in the new profile. Take sufficient time to try (at least 15-30 minutes or so) the newly created profile, especially if the original issue you’re facing is sporadic. If everything works fine in the new user profile, the problem may be caused by corrupt cache files (icon, thumbnail, Quick access, etc.) in the original user profile.<\/p>\n
    <\/a>Clear the Cache<\/h3>\n
    Do some cleanup work in your original profile:<\/p>\n
      \n
    1. Clear and Rebuild the Icon Cache in Windows<\/a><\/li>\n
    2. Clear Thumbnail Cache & Temp Files Using Disk Cleanup<\/a><\/li>\n
    3. Reset your Folder View Settings Completely<\/a><\/li>\n
    4. Reset Quick Access<\/a> (see “Option 4” on the page.)<\/li>\n<\/ol>\n
      <\/a>Update your Drivers<\/h3>\n
      Check for updated drivers for your hardware, especially your video card. Try reverting to the default scaling level to test if you’re using custom scaling. An issue was reported in Windows 10, where Explorer crashed when scaling was set to 175% or higher in specific configurations.<\/p>\n
      <\/a>Advanced Troubleshooting Options<\/h3>\n
      If all else fails, here are your options (in no particular order):<\/p>\n
        \n
      1. Run Process Monitor, start a trace, reproduce the problem and save it to a .PML<\/code> log file. You may zip it<\/u> and send it to me. Also, check out the Process Monitor<\/a> tutorials<\/a>.<\/li>\n
      2. Run a thorough malware scan using Malwarebytes Anti-malware. If you find anything suspicious or the tool can’t remove the infestation, register with a reputed Malware removal forum and seek expert advice.<\/li>\n
      3. Post your issue in a Windows forum, mentioning what you’ve tried earlier. Then, if someone can help with debugging your Explorer crash dump, the root cause may be determined easily.<\/li>\n
      4. Consider resetting Windows or performing a repair installation. Please be sure to backup your data beforehand whatever repair method you use.<\/li>\n<\/ol>\n
