✅ Method 2: Utilizing the System File Checker (SFC)

The System File Checker (SFC) is a built-in Windows utility that scans and restores critical system files, including many DLLs. It’s an indispensable tool for resolving issues caused by file corruption. To use it, you must run the Command Prompt as an administrator. The key command to execute is sfc /scannow. This process can take a significant amount of time, as it meticulously checks the integrity of protected operating system files. If the SFC utility detects a corrupted or missing file, it will automatically attempt to replace it with a cached copy stored on your system, often resolving stubborn DLL issues without external intervention.

—

🧹 Method 3: Running the DISM Tool for Deeper System Repair

When the SFC tool is unable to fix the issue, the corruption may lie in the underlying system image that SFC uses for its repair process. The Deployment Image Servicing and Management (DISM) tool is designed to address this. DISM is used to prepare, modify, and repair Windows images. When tackling DLL issues, the DISM Restore Health command is particularly useful. This command attempts to repair the Windows component store corruption. You should run this command before re-running SFC if the initial SFC scan failed. The command typically involves using switches like /Online /Cleanup-Image /RestoreHealth within the administrative Command Prompt.
