How to Fix Windows Explorer Not Responding in Windows 10

Windows Explorer (now called File Explorer) freezing or showing “Not Responding” is a common frustration on Windows 10. This guide walks you through the most effective fixes, from quick restarts to deeper system checks, so you can get your files and folders working smoothly again. No special tools are required—just a few minutes and your Windows login.

What You’ll Need

Administrator access to your Windows 10 PC (to run some commands).
Your Windows login password (if you’re not already signed in).
Patience—some steps require a restart.

Step-by-Step

Force-restart Explorer (quick fix). Press Ctrl+Shift+Esc to open Task Manager. Under the “Processes” tab, find “Windows Explorer” (it may be listed as “File Explorer”). Right-click it and choose “Restart.” This kills and relaunches the shell without restarting your PC. If the whole system is frozen, press Ctrl+Alt+Del and select “Task Manager” from the blue screen.
Run a virus scan. Malware can cause Explorer to hang. Open Windows Security (type “Windows Security” in the Start menu), go to “Virus & threat protection,” and click “Quick scan.” If it finds anything, follow the prompts to remove it. For a deeper check, click “Scan options” and choose “Full scan” (this can take an hour or more).
Check for Windows updates. Go to Settings > Update & Security > Windows Update and click “Check for updates.” Install any pending updates, then restart your PC. Updates often include fixes for Explorer bugs.
Run the System File Checker (SFC). Corrupted system files can cause Explorer to crash. Open Command Prompt as administrator (right-click Start > “Command Prompt (Admin)” or “Windows PowerShell (Admin)”). Type sfc /scannow and press Enter. Wait for the scan to finish (it may take 15–30 minutes). If it finds errors, it will try to repair them automatically.
Run DISM to repair the system image. If SFC doesn’t fix it, run DISM (Deployment Imaging Service and Management Tool). In the same admin window, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This can take 20–40 minutes. After it completes, restart your PC and run sfc /scannow again.
Clear File Explorer history. Open File Explorer, click the “View” tab, then click “Options” (or “Change folder and search options”). In the “General” tab, under “Privacy,” click “Clear” to remove the Quick access history. This can fix hangs caused by corrupted thumbnails or recent files data.
Disable startup items that interfere. Some third-party apps (like cloud sync tools or shell extensions) can make Explorer unresponsive. Open Task Manager > “Startup” tab. Right-click any non-Microsoft item (e.g., Dropbox, OneDrive, Adobe updater) and select “Disable.” Restart your PC and see if the problem persists. If it’s gone, re-enable items one by one to find the culprit.
Run a disk check. Hard drive errors can also cause Explorer to hang. Open an admin Command Prompt and type chkdsk /f /r on the drive where Windows is installed (usually C:). You’ll be asked to schedule a check for the next restart—type “Y” and restart. The check can take a while, but it will fix file system errors.
Create a new user profile. If Explorer only freezes for your account, your profile may be corrupted. Go to Settings > Accounts > Family & other users, and add a new user with administrator rights. Log into that new account and test Explorer. If it works, you can migrate your files.
Perform a clean boot. This starts Windows with only essential drivers and programs, helping isolate the cause. Press Win+R, type msconfig, and press Enter. In the “General” tab, select “Selective startup” and uncheck “Load startup items.” Go to the “Services” tab, check “Hide all Microsoft services,” then click “Disable all.” Click OK and restart. If Explorer works fine, a third-party service is the culprit—re-enable services in batches to find it.

Common Mistakes

Skipping the SFC scan before DISM. Always run SFC first; if it fails, then use DISM. Running DISM alone may not fix all corruptions.
Killing Explorer from Task Manager incorrectly. If you end the task instead of restarting, your taskbar and desktop icons disappear. To bring them back, press Ctrl+Shift+Esc, click “File” > “Run new task,” type explorer.exe, and press Enter.
Disabling all startup items permanently. You might disable a security tool or driver you need. Only disable items you recognize as non-essential.
Ignoring pending Windows updates. An outdated OS can have known Explorer bugs that are already fixed in a later update.
Running chkdsk on the wrong drive. Make sure you check the drive where Windows is installed (usually C:).

Tips

Keep your system clean. Regularly run Disk Cleanup (search “Disk Cleanup” in Start) to remove temporary files that can clutter Explorer.
Update your graphics driver. Outdated or faulty GPU drivers can cause Explorer to freeze, especially when rendering thumbnails. Go to Device Manager, expand “Display adapters,” right-click your GPU, and choose “Update driver.”
Use “Restart” instead of “Shut down” when you have issues. Windows 10’s “Fast Startup” can cause problems; a full restart clears the kernel cache.
Disable thumbnail previews temporarily. In File Explorer, click the “View” tab and select “Details” to avoid generating thumbnails, which can be heavy on some systems.
Consider a Registry backup before making changes. If you edit the registry (not covered here), always export a backup first.

Troubleshooting

If the steps above don’t resolve the issue, try these additional checks:

Check for overheating. If your PC shuts down or freezes randomly, overheating can cause Explorer to hang. Monitor your CPU temperature with a free tool like Core Temp (but don’t rely on it as a final diagnosis).
Test your RAM. Faulty memory can cause random crashes. Use the built-in Windows Memory Diagnostic (search “Windows Memory Diagnostic” in Start) and restart to run the test.
Look for third-party shell extensions. Tools like 7-Zip or WinRAR add context menu entries that can slow Explorer. Use a free utility like ShellExView to disable non-Microsoft extensions (but be careful—disabling the wrong one can break things).
Try a System Restore. If the issue started recently, use System Restore to roll back your PC to a point before the problem. Search “Create a restore point” in Start, click “System Restore,” and follow the wizard.
Reset Windows (last resort). If nothing works, you can reset Windows 10 via Settings > Update & Security > Recovery > “Reset this PC.” Choose “Keep my files” to preserve your personal data, but this will remove installed apps.

Frequently Asked Questions

Why does Windows Explorer keep not responding?

Common causes include corrupted system files, outdated drivers, malware, or a conflicting third-party program. It can also be due to a failing hard drive or too many files in one folder.

Will I lose my files if I restart Explorer?

No. Restarting Explorer only closes the file manager and the desktop shell. Your open files in other programs are not affected, though you may lose unsaved changes in Notepad if you had it open.

Can I prevent Explorer from freezing in the future?

Keep Windows updated, run periodic virus scans, avoid filling your desktop with thousands of shortcuts, and disable unnecessary startup programs. Also, regularly clean temporary files.

Is it safe to run sfc /scannow?

Yes, it’s a built-in Windows tool that checks for corrupted system files and repairs them. It’s safe and doesn’t affect your personal files.

What if the problem only happens when I open a specific folder?

That folder may have a corrupted thumbnail cache or a file that triggers a bug. Try clearing the thumbnail cache (Disk Cleanup > “Thumbnails”) or move the folder to a different location to test.

Do I need to reinstall Windows if nothing works?

Not necessarily. A “Reset this PC” (keeping your files) often fixes persistent issues without a full reinstall. If that fails, a clean install is the last resort, but it will remove all your apps and settings.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
