Summary: File Explorer closes alone, hangs on This PC, or won't open folders? Restart Explorer, clear history, disable preview handlers, and fix shell extensions.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
File Explorer closes when you open **Downloads**, freezes on **This PC**, or sits with **Not responding** in the title bar. Because `explorer.exe` is also the desktop shell, a crash can take the taskbar and wallpaper with it.

> **Only one application crashing?** See [app keeps crashing or won't open](https://www.mytechnician.tech/tips/fix-app-crashing-wont-open/). **Whole shell unstable?** Also check [Start menu not opening](https://www.mytechnician.tech/tips/fix-windows-11-start-menu-not-opening/) and [taskbar not working](https://www.mytechnician.tech/tips/fix-windows-11-taskbar-not-working-disappearing/).

## Step 1: Note When It Crashes
The trigger tells you which fix applies, and it saves working through all seven.

| When it crashes | Likely cause | Go to |
|---|---|---|
| Right-clicking a file | Third-party shell extension | Step 5 |
| Opening a specific folder | Thumbnail or preview handler | Steps 3 and 4 |
| Opening **This PC** | Offline network drive or failing disk | Steps 6 and 7 |
| On any window at all | System files or profile | Steps 2 and 8 |
| Only with video or PDF files | Codec or preview handler | Step 4 |

Also check **Event Viewer** → **Windows Logs** → **Application** for an **Application Error** naming the faulting module. That `.dll` name often identifies the culprit outright—see [use Event Viewer to find why your PC crashed](https://www.mytechnician.tech/tips/how-to-read-event-viewer-find-crash-cause/).

## Step 2: Restart Explorer and Repair System Files
1. `Ctrl + Shift + Esc` → **Windows Explorer** → **Restart**.
2. Then, in **Terminal (Admin)**:

```cmd
DISM /Online /Cleanup-Image /RestoreHealth
```
```cmd
sfc /scannow
```

3. Install any pending Windows updates and restart.

## Step 3: Clear File Explorer History
A broken Quick Access entry—usually pointing at a disconnected network share—crashes the window as it opens.

1. Open File Explorer → ⋯ → **Options** → **General** tab.
2. Set **Open File Explorer to:** **This PC** rather than **Home** or Quick access.
3. On the same tab, under **Privacy**, untick both **Show recently used files** and **Show frequently used folders**, then click **Clear**.

If Explorer will not stay open long enough, rename this folder from Safe Mode or a command prompt:

```
%AppData%\Microsoft\Windows\Recent\AutomaticDestinations
```

Rename it to `AutomaticDestinations.old`—Windows rebuilds it.

## Step 4: Turn Off Preview and Thumbnails
Preview handlers from PDF readers, codec packs, and old media tools are among the most common causes.

1. In File Explorer: **View** → **Show** → untick **Preview pane** and **Details pane**.
2. Then ⋯ → **Options** → **View** tab → tick **Always show icons, never thumbnails**.
3. Test the folder that used to crash.

If that fixes it, uninstall the codec pack or PDF tool responsible, or leave thumbnails off for that folder type.

Clear the thumbnail cache while you are here—`cleanmgr` → tick **Thumbnails**.

## Step 5: Find the Bad Shell Extension
Crashes on **right-click** are nearly always a third-party context-menu handler: archive tools, cloud sync clients, old antivirus, or GPU utilities.

1. Download **ShellExView** from NirSoft, or use **Autoruns** → **Explorer** tab.
2. Sort by company, and hide all Microsoft entries.
3. Disable the non-Microsoft extensions in groups of five, restarting Explorer between tests.
4. When the crash stops, re-enable them one at a time to identify the offender, then update or uninstall that application.

A quick test that avoids the tool entirely: [restore the classic right-click menu](https://www.mytechnician.tech/tips/restore-classic-right-click-context-menu-windows-11/) forces Windows to load the legacy menu, which changes which handlers run.

## Step 6: Disconnect Dead Network Drives
A mapped drive to an unreachable NAS or server makes Explorer wait 30 seconds or more on every window, which reads as a freeze.

1. **This PC** → right-click each mapped drive → **Disconnect** for any you no longer use.
2. Check for shortcuts in Quick Access pointing at unavailable shares and remove them.

## Step 7: Check the Disk
Explorer hanging on C: or an external drive can be disk errors.

```cmd
chkdsk C: /scan
```

For external drives: [fix a corrupted USB or external drive](https://www.mytechnician.tech/tips/fix-corrupted-usb-external-drive/). A nearly full C: also causes stalls: [free up disk space](https://www.mytechnician.tech/tips/free-up-disk-space-c-drive-full-windows-11/). And check SMART data: [check SSD or hard drive health](https://www.mytechnician.tech/tips/check-ssd-hard-drive-health-windows-11/).

## Step 8: Reset Folder Views
When one type of folder always crashes—typically a folder Windows has decided contains pictures—the saved view settings are corrupt.

In **Terminal (Admin)**:

```cmd
reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\BagMRU" /f
```
```cmd
reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags" /f
```

Sign out and back in. You lose customised folder view settings, which is a small price.

## Working Around It Meanwhile
Run a separate Explorer process that does not depend on the shell:

```cmd
explorer /separate
```

That gives you a window to copy files with while the main shell is unstable.

## Still Crashing?
Create a new local user account (**Settings** → **Accounts** → **Other users**) and test there.

* **Stable in the new account** → your profile is damaged. Migrate to it, or see [fix "signed in with a temporary profile"](https://www.mytechnician.tech/tips/fix-temporary-profile-windows-11/).
* **Crashing there too** → run an in-place repair install keeping files and apps: [reinstall Windows without losing data](https://www.mytechnician.tech/tips/reinstall-windows-without-losing-data/).

Pause OneDrive as a test either way—[fix OneDrive sync issues](https://www.mytechnician.tech/tips/fix-onedrive-sync-issues-windows-11/) if Explorer hangs specifically on synced folders.
