How to fix "sfc.dll is either not designed to run on Windows or it contains an error"?

Issue: Hi, I have recently updated Windows and now I can no longer open my browser because I receive the “sfc.dll is either not designed to run on Windows or it contains an error” message. Any tips would be appreciated.

Solved Answer

Dynamic Link Libraries (DLLs) are foundational elements in the Windows operating system, serving as modular libraries of executable functions or data. These libraries are used by Windows applications to perform various functions without the need to incorporate these functions into the application itself. This design promotes efficient use of system resources and code, as multiple applications can share the capabilities provided by a single DLL file, reducing redundancy.

The “sfc.dll” file is a specific type of DLL that plays a critical role in the Windows environment. It is associated with the Windows File Protection (WFP) service, which is essential for maintaining the integrity of system files. WFP is designed to prevent programs from replacing critical Windows system files.

If these files are modified or replaced by unauthorized means, the WFP service uses the “sfc.dll” file to restore the original, correct versions of these system files. This process is crucial for the stability and security of the operating system, as it helps prevent system crashes and ensures that the system operates smoothly and securely.

Despite their importance, DLL files like “sfc.dll” can encounter issues, such as the error “sfc.dll is either not designed to run on Windows or it contains an error.” This error can occur due to a version mismatch between the DLL file and the Windows version in use, corruption or loss of the DLL file, malware infections altering the DLL, or software conflicts on the system. When this error arises, it indicates a failure in the functioning of the “sfc.dll,” potentially leading to application malfunctions or system instability.

Addressing this error typically involves identifying the underlying cause, such as restoring the correct version of the DLL, running malware scans, resolving software conflicts, or performing system updates.

Such tools are designed to automatically diagnose and rectify issues within the Windows operating system, including those related to crucial DLL files, thereby ensuring the system's efficient and secure operation.

Fix 1. Run SFC and DISM

Running System File Checker and Deployment Image Servicing and Management tools can effectively resolve the sfc.dll error in most cases. SFC scans for and repairs corrupt or missing system files, while DISM fixes Windows corruption errors that might prevent SFC from functioning correctly. Together, they offer a comprehensive solution to DLL-related issues.

  • Type cmd in Windows search.
  • Right-click on Command Prompt and pick Run as administrator.
  • User Account Control window will show up – click Yes when prompted.
  • Then, copy and paste the following command, pressing Enter after:
    sfc /scannow
  • Wait till the scan is finished. If Windows finds system file integrity violations, it will attempt to fix them. After this, use the set of the following commands, pressing Enter each time:
    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth
  • (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
  • Close down the Command Prompt and restart your device.
