Quick answer
First restart the Explorer process via Task Manager, then check system file integrity with `DISM` and `sfc /scannow`. If the problem returns, clear the icon cache, disable unnecessary context menu extensions and update the graphics driver. Only as a last resort consider a new user profile or restoring to a previous restore point.
How to recognize the problem
- Explorer closes by itself and the desktop briefly disappears
- Folders open very slowly or show "Not responding"
- The taskbar and desktop icons flicker or reload
- Right-clicking a file freezes the menu for a few seconds
- Windows shows a message that Windows Explorer has stopped working
Most common causes
Corrupted system files
Errors in system files or the system image often cause Explorer crashes. Checking with `sfc` and `DISM` finds and repairs such problems.
Icon and thumbnail cache
A corrupted icon and thumbnail cache can freeze folder views, especially in folders with many images and videos.
Context menu extensions
Third-party tools add items to the right-click menu, and a faulty extension can block Explorer every time the menu opens.
Graphics driver
An outdated or faulty graphics driver causes flickering and desktop crashes, especially after a major update.
Corrupted user profile
If the problem occurs only on one account, the cause is probably a corrupted profile or its settings, not the whole system.
Step-by-step fix
- 1
Restart the Explorer process
Press
Ctrl + Shift + Escto open Task Manager, then on theProcessestab findWindows Explorer. Right-click it and selectRestart. The desktop and taskbar will briefly reload, and open folders will close. - 2
Check system files
Open Start, type
cmd, then right-clickCommand Promptand selectRun as administrator. First runDISM /Online /Cleanup-Image /RestoreHealthand wait for it to finish, thensfc /scannow. Restart the computer. - 3
Clear the icon and thumbnail cache
Open
Settings > System > Storage > Temporary filesand remove items related to thumbnails and cache. If the problem persists, inDisk Cleanup(cleanmgr) checkThumbnailsand confirm deletion. The cache is rebuilt automatically the next time you open a folder. - 4
Disable unnecessary context menu extensions
Windows does not have a built-in overview of all right-click extensions. Create a restore point, then run Microsoft Sysinternals
Autorunsand on theExplorertab disable only non-Microsoft items (archives, cloud sync, search). Restart Explorer or the computer and check whether the menu opens without freezing. If you do not want an extra tool, temporarily uninstall programs that add right-click items one by one until you find the culprit. - 5
Update the graphics driver
Open
Device Manager, expandDisplay adapters, right-click the card and selectUpdate driver. If Windows does not find a newer driver, download it from the computer or chip manufacturer's website. After installation, be sure to restart the system. - 6
Check Windows updates
Go to
Settings > Windows Updateand clickCheck for updates. Install all available updates, including optional driver updates. Updates often contain fixes for known Explorer bugs. - 7
Test another user account
Create a temporary local account in
Settings > Accounts > Other usersand sign in to it. If Explorer does not crash there, the problem is in your profile. In that case, move your files to the new account or reset the profile with a prior backup and help from IT support. - 8
Restore the system to a previous state
If the problem appeared after installing a program or update, open
Control Panel > Recovery > Open System Restoreand select a point before the problem appeared, if system protection is enabled and the point exists. This action restores system files and settings but does not delete personal files. Back up important data before restoring.
If nothing helped: clean environment check
When all steps have been tried and Explorer still crashes, check whether a third-party program is the cause. Create a restore point. Open msconfig, on the Services tab check Hide all Microsoft services and click Disable all, then on the Startup tab open Task Manager and disable all items. Restart the computer and check the behavior. If the system is stable, enable groups of services and programs until the problem returns, then remove or update the program causing it. After the test, be sure to re-enable the services. If a third-party security program is installed, enable it immediately after the test. This procedure should not be done on a business computer managed by IT, as it can disconnect it from the domain and security tools.
How to prevent it
- Regularly install Windows updates and driver updates
- Do not install several archive and sync tools that hook into the right-click menu
- Occasionally delete temporary files and the thumbnail cache
- Create restore points before major system changes
When to call a professional
If Explorer crashes even after all steps, or if the problem occurs on multiple computers in the office, it is better to contact IT support. They can check profiles, group policies and security tools that affect system operation.

Does clearing the icon cache remove my files?
No. Only the thumbnail and icon cache is deleted, which Windows rebuilds automatically. Your documents, images and video files remain untouched.
Why does Explorer crash only when I open a certain folder?
The most common cause is a corrupted thumbnail or a file that Explorer tries to display. Clear the thumbnail cache and check whether the problem repeats in a folder with fewer files.
Is it safe to run `sfc` and `DISM` commands?
Yes, these are standard Microsoft tools for checking and repairing system files. You need to run them as administrator and wait for the process to finish.
