Most File Explorer crashes are resolvable without reinstalling Windows by systematically addressing software, driver, or profile issues, and the problem can typically be fixed by following these steps in order.

Windows File Explorer not responding or crashing is a common issue that can disrupt your workflow. It usually stems from system overload, corrupted files, problematic shell extensions, or conflicts with third-party software. Here’s how to diagnose and fix it effectively.

1. Restart Windows Explorer via Task Manager

When File Explorer freezes, the quickest fix is to restart it:

• Press Ctrl Shift Esc to open Task Manager.
• Go to the Processes tab.
• Find Windows Explorer under "Background processes".
• Right-click it and select Restart.

This often resolves temporary hangs without needing a full reboot.

If it crashes again immediately, move on to deeper troubleshooting.

2. Run System File Checker (SFC)

Corrupted system files can cause Explorer to crash.

• Open Command Prompt as Administrator:
  • Press Win X and choose Terminal (Admin) or Command Prompt (Admin).
• Type this command and press Enter:

  sfc /scannow

• Wait for the scan to complete (can take 15–30 minutes).
• If issues are found and repaired, restart your PC.

SFC checks and repairs protected system files. It's one of the most effective tools for Windows stability issues.

3. Check for Problematic Shell Extensions

Third-party apps (like cloud storage, file compression tools, or context menu add-ons) often inject shell extensions that can crash Explorer.

• Use a tool like ShellExView (by NirSoft) to disable non-Microsoft extensions:
  • Download ShellExView from the official site.
  • Run it as administrator.
  • Sort by Company and disable all non-Microsoft entries (especially those related to apps you’ve recently installed).
  • Restart Explorer or your PC.

Re-enable extensions one by one to identify the culprit if the problem goes away.

4. Disable Preview Pane and Other Explorer Features

The Preview Pane, Details Pane, or thumbnail generation can cause Explorer to hang, especially with large media files.

• Open File Explorer, go to the View tab.
• Click Options > Change folder and search options.
• In the View tab of Folder Options:
  • Check "Always show icons, never thumbnails"
  • Check "Turn off preview pane"
  • Check "Turn off thumbnail cache" (optional)
• Click Apply and restart Explorer.

This reduces Explorer’s memory and CPU load, especially on older systems.

5. Update or Roll Back Graphics Drivers

Outdated or buggy graphics drivers can cause UI-related crashes.

• Press Win X > Device Manager.
• Expand Display adapters.
• Right-click your GPU and choose Update driver.
• Or, if the issue started recently, choose Roll back driver.

Also consider updating via the manufacturer’s site (NVIDIA, AMD, Intel, or laptop OEM).

6. Scan for Malware

Malware can hook into Explorer and cause instability.

• Run a full scan using Windows Security (Defender):
  • Go to Settings > Privacy & Security > Windows Security > Virus & threat protection > Full scan.
• Alternatively, use a trusted third-party antivirus.

7. Create a New User Profile

Sometimes the issue is tied to a corrupted user profile.

• Create a new local user account:
  • Settings > Accounts > Family & other users > Add account
• Log into the new account and test File Explorer.
• If it works fine, migrate your files to the new profile.

8. Disable OneDrive Sync (if applicable)

OneDrive integration can sometimes cause Explorer crashes, especially during sync.

• Right-click the OneDrive icon in the system tray.
• Choose Settings > Sync and backup > Choose folders.
• Try disabling sync temporarily to test stability.

Or, uninstall OneDrive completely (if not needed):

%systemroot%\SysWOW64\OneDriveSetup.exe /uninstall  (32-bit)
%systemroot%\System32\OneDriveSetup.exe /uninstall   (64-bit)

Bonus: Clean Boot to Isolate Conflicts

Perform a clean boot to see if background apps are causing the crash.

• Press Win R, type msconfig, and hit Enter.
• Under Services, check "Hide all Microsoft services", then click Disable all.
• Go to Startup tab > Open Task Manager > disable all startup items.
• Restart the PC.

If Explorer works fine, re-enable services/startup apps gradually to find the offender.

Most File Explorer crashes are fixable without reinstalling Windows. Start with restarting Explorer and running SFC, then move to shell extensions and drivers. The key is isolating the cause—whether it’s software, driver, or user profile related.

Basically, don’t panic—there’s almost always a fix.
