File Explorer Won't Open on Windows?

You click the folder icon and nothing happens. Or it opens then crashes. Or it opens but spins forever. Here's the fix list, in order.

1. Restart Windows Explorer

This is the single most effective fix. Faster than restarting the whole PC.

1. Press Ctrl + Shift + Esc (opens Task Manager)
2. In the Processes tab, scroll to find Windows Explorer
3. Right click > Restart
4. Your taskbar disappears for a second then comes back. Normal.
5. Try opening File Explorer

2. Change File Explorer to open This PC instead of Quick Access

Quick Access tries to load recent files from network drives, OneDrive, etc. If any are slow, File Explorer hangs or fails to open.

1. Press Windows + R, type control folders, press Enter
2. Folder Options window opens
3. "Open File Explorer to:" change from Quick Access to This PC
4. Click Clear next to "Clear File Explorer history"
5. Click OK

3. Clear File Explorer cache

Same Folder Options window as above:

1. General tab
2. Click Clear under Privacy
3. Untick "Show recently used files" and "Show frequently used folders" if you don't need them
4. OK

4. Run System File Checker (SFC)

Repairs corrupted Windows system files.

1. Right click Start button > Terminal (Admin) or PowerShell (Admin)
2. Type: sfc /scannow
3. Press Enter, wait 10-15 minutes
4. If it found issues, restart and try File Explorer

5. Check for Windows updates

Microsoft has shipped File Explorer fixes regularly, especially in Windows 11.

1. Settings > Windows Update
2. Check for updates
3. Install everything pending
4. Restart

6. Run DISM

Deeper than SFC. Repairs the Windows image.

1. Terminal (Admin)
2. Type: DISM /Online /Cleanup-Image /RestoreHealth
3. Press Enter, wait. This can take 20+ minutes
4. When done, run sfc /scannow again
5. Restart

7. Create a new user account (test)

Sometimes the issue is in your user profile, not Windows itself. Test by creating a new local account.

1. Settings > Accounts > Other users
2. Add account > "I don't have this person's sign-in information" > "Add a user without a Microsoft account"
3. Create a name and password
4. Log out and log into the new account
5. Try File Explorer

If it works in the new account, your original profile is corrupted. You can migrate your files over and use the new account.

Bonus: Open File Explorer with a keyboard shortcut

If your taskbar icon isn't working, you can still launch File Explorer with Windows + E. Useful for testing whether the icon itself is the problem.
