Windows Explorer keeps crashing usually because of a faulty third-party shell extension (an add-on that appears in right-click menus), corrupt system files, an outdated graphics driver, a damaged thumbnail cache, or a specific corrupt file or folder it tries to display. When Explorer crashes, the taskbar, Start menu, and desktop icons briefly disappear and then reload. Finding which add-on or file triggers it is the key to stopping it.
Why this happens
Explorer.exe runs the desktop, taskbar, and File Explorer, and it loads add-ons from other programs. When one of those misbehaves, Explorer crashes. Common causes include:
- A buggy shell extension added by a third-party program, often shown in right-click menus.
- Corrupt Windows system files.
- An outdated or faulty graphics driver.
- A corrupt thumbnail or icon cache.
- A damaged file, video, or image that Explorer tries to preview or thumbnail.
- Malware, or a recent update or program that introduced a conflict.
Is this normal?
No. An occasional reload after a big change can happen, but Explorer repeatedly crashing, especially when you right-click, open a folder, or view certain files, is not normal and points to a specific cause.
Does it cause any problems?
Yes. Each crash makes the taskbar and desktop vanish and reload, interrupts what you are doing, and can lose the position of open windows. It makes the PC frustrating to use even though the rest of Windows keeps running.
How to fix or check it
- Note when it crashes: on right-click, when opening a folder, or when viewing a file type. This narrows the cause.
- Repair system files: open Command Prompt as administrator and run sfc /scannow, then DISM /Online /Cleanup-Image /RestoreHealth.
- Update your graphics driver from the maker's website, and install the latest Windows updates.
- Clear the thumbnail and icon cache using Disk Cleanup, or delete the thumbcache files in the Explorer cache folder.
- Disable third-party shell extensions with a tool such as ShellExView, turning them off in groups to find the bad one.
- Check Event Viewer under Windows Logs, Application for the faulting module name, which often names the add-on or driver at fault.
- Turn off the preview and details panes in File Explorer if crashes happen when selecting media files.
- Run a malware scan, and test a new user account to see if the problem follows your profile.
Frequently asked questions
How do I find which add-on is crashing Explorer?
Check Event Viewer for the faulting module, or use ShellExView to disable non-Microsoft shell extensions in batches until the crashes stop, then re-enable them one at a time.
Why does the taskbar disappear when Explorer crashes?
The taskbar, Start menu, and desktop are all drawn by explorer.exe. When it crashes they vanish, and they reappear once Windows restarts the process automatically.
Can a bad file cause the crashes?
Yes. A corrupt image or video can crash Explorer when it tries to make a thumbnail. Turning off thumbnails and the preview pane, then clearing the thumbnail cache, often stops it.
