Fix Windows Explorer Not Responding

If Windows Explorer (File Explorer) freezes, shows a “Not Responding” message, or keeps restarting, the fastest fix is to restart it from Task Manager, then clear the Explorer history and run a system file check. This article walks through those steps and several others, from quick refreshes to deeper repairs, so you can get your files and folders working again.

Why Explorer Freezes

Windows Explorer is the shell of the operating system — it draws your desktop, taskbar, File Explorer windows, and the Start menu. When it hangs, the whole interface can become unresponsive. Common triggers include:

• Corrupted thumbnail cache or icon cache
• A faulty third-party shell extension (like a cloud sync app or archive tool)
• Network drives that are slow or offline
• Too many files in one folder, especially with automatic previews
• Outdated or buggy graphics drivers
• System file corruption after an update or crash

Sometimes the problem is a one-off glitch; other times it recurs every few minutes. The steps below start with the least invasive and move to more thorough repairs.

Quick Restart from Task Manager

If the taskbar is still clickable, the quickest fix is to restart Explorer itself:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Under the Processes tab, find Windows Explorer (it may be under “Apps” or “Windows processes”).
3. Right-click it and choose Restart.

Your taskbar and desktop icons will disappear for a second and then come back. This clears a hung Explorer process without logging you out. If the desktop is completely frozen, press Ctrl + Alt + Del and choose Task Manager from the screen that appears.

Clear File Explorer History and Cache

If Explorer keeps freezing when you open certain folders, the stored history and thumbnail cache may be corrupted. Clearing them is safe — you only lose the list of recent folders and the small preview images.

1. Open File Explorer (if it opens at all).
2. Click the View tab on the ribbon, then click Options (or “Change folder and search options”).
3. In the General tab, under Privacy, click Clear to wipe the File Explorer history.
4. Go to This PC, right-click your main drive (usually C:), and choose Properties.
5. On the General tab, click Disk Cleanup, then select Thumbnails and any other cache types you want to remove, and click OK.

If the thumbnail cache is the culprit, this often stops the freezing in folders full of images or videos.

Disable Problematic Startup Items and Shell Extensions

Many Explorer freezes are caused by third-party add-ons that load into the shell. Cloud storage apps (OneDrive, Dropbox, Google Drive), archive tools (7-Zip, WinRAR), and clipboard managers are common offenders. To test this:

1. Open Task Manager and go to the Startup tab.
2. Disable any item you don’t need at startup, especially ones you recognize from the list above.
3. Restart your PC and see if the freezing stops.

If disabling startup items doesn’t help, use a tool like ShellExView (from NirSoft) to temporarily disable non-Microsoft shell extensions. You can re-enable them one by one to find the exact culprit. This is a more advanced step, but it’s the only way to identify a specific extension without uninstalling software blindly.

Run System File Checker and DISM

Corrupted system files can cause Explorer to crash repeatedly. Windows has built-in tools to find and repair them:

1. Right-click the Start button and choose Terminal (Admin) or Command Prompt (Admin).
2. Type sfc /scannow and press Enter. This scans protected system files and replaces damaged ones. It can take 10–20 minutes.
3. If SFC finds errors it can’t fix, run DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This repairs the Windows image itself.
4. Restart your PC after the commands finish.

These commands are safe and don’t touch your personal files. They’re the standard first step for any Windows system file problem.

Check for Driver and Windows Updates

An outdated or buggy display driver can make Explorer freeze, especially when rendering thumbnails or animations. To update:

1. Press Windows + I to open Settings.
2. Go to Windows Update and click Check for updates. Install any pending updates, including optional driver updates.
3. For your graphics driver specifically, go to Device Manager, expand Display adapters, right-click your GPU, and choose Update driver.

If the problem started after a recent update, you can also roll back the driver: in Device Manager, right-click the GPU, choose Properties, go to the Driver tab, and click Roll Back Driver if the option is available.

When to Use a Clean Boot

A clean boot starts Windows with only the essential drivers and programs, which tells you whether a background service is causing the freeze. Here’s how:

1. Press Windows + R, type msconfig, and press Enter.
2. In the Services tab, check Hide all Microsoft services, then click Disable all.
3. Go to the Startup tab and click Open Task Manager. Disable all startup items there too.
4. Click OK and restart.

If Explorer works fine in clean boot mode, re-enable services and startup items in batches until the freeze returns. That pinpoints the offender. After testing, run msconfig again and re-enable everything or just the items you need.

Frequently Asked Questions

Why does Explorer keep restarting on its own?

Explorer can crash and restart automatically when a shell extension or a system file is corrupted. The restart loop is Windows trying to recover the desktop. Follow the steps above — starting with restarting Explorer, then clearing caches, then running SFC — to break the loop.

Will I lose my files if I restart Explorer?

No. Restarting Explorer only closes the file manager windows and redraws the desktop. Any files you have open in other programs (like Word or a browser) are not affected. Unsaved work in Notepad or similar apps that are part of Explorer (like the desktop) will not be lost because those apps run separately.

How do I open File Explorer if the taskbar is frozen?

Press Windows + E to open a new File Explorer window. If that doesn’t work, press Ctrl + Shift + Esc to open Task Manager, then click File > Run new task, type explorer.exe, and click OK. This launches a fresh Explorer process.

Can a virus cause Explorer to stop responding?

Yes, malware can interfere with Explorer, especially if it hooks into the shell or modifies system files. If you’ve tried the usual fixes and the problem persists, run a full scan with Windows Defender or your preferred antivirus. Also check the Autoruns tool from Microsoft Sysinternals to see if any suspicious entries are loading into Explorer.

Should I reinstall Windows to fix this?

Only as a last resort. The steps above resolve the vast majority of Explorer freezes. If none of them work, you can try a repair install using the Windows Media Creation Tool, which keeps your files and apps while reinstalling the OS. A full reset is the final option, but back up your data first.
