How to Fix Errors Without Downloading

Never download DLL files from third-party websites. They often contain malware or outdated file versions. You can fix the error using built-in Windows tools.

1. Run the System File Checker (SFC)

This tool scans all protected system files and replaces corrupted ones with a cached copy.

Press the Windows Key.
Type cmd.
Right-click Command Prompt.
Select Run as administrator.
Type sfc /scannow and press Enter.
Wait for the scan to finish.
Restart your computer.

2. Run the DISM Tool

If the SFC tool cannot find the required files, use the Deployment Image Servicing and Management (DISM) tool to repair the system image.

Open Command Prompt as administrator (same steps as above).
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
This process requires an internet connection to download fresh copies of broken files from Windows Update.
Restart your computer after it finishes.

3. Restart the Windows Explorer Process

If the error causes the network menu to freeze or crash, restarting the shell UI can help.

Press Ctrl + Shift + Esc to open Task Manager.
Look for Windows Explorer in the list.
Right-click it and select Restart.
