What are SDWinLogon.dll Error Messages?

Dynamic Link Library SDWinLogon.dll Errors

SDWinLogon.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like SDWinLogon.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like blindman.exe - to follow. These files were created so that multiple programs (eg. Spybot - Search & Destroy) could share the same SDWinLogon.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when SDWinLogon.dll is attempted to be loaded either when Spybot - Search & Destroy is starting up, or in some cases already running. Some of the most common SDWinLogon.dll errors include:

Access Violation at address - SDWinLogon.dll.
SDWinLogon.dll could not be found.
Cannot find C:\SpybotPortable\App\Spybot\SDWinLogon.dll.
Cannot register SDWinLogon.dll.
Cannot start Spybot - Search & Destroy. A required component is missing: SDWinLogon.dll. Please install Spybot - Search & Destroy again.
Failed to load SDWinLogon.dll.
The application has failed to start because SDWinLogon.dll was not found.
The file SDWinLogon.dll is missing or corrupt.
This application failed to start because SDWinLogon.dll was not found. Re-installing the application may fix this problem.

Your SDWinLogon.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Spybot - Search & Destroy), or deleted by a malware infection. Furthermore, SDWinLogon.dll file corruption could be caused from a power outage when loading Spybot - Search & Destroy, system crash while loading SDWinLogon.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix SDWinLogon.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your SDWinLogon.dll issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the SDWinLogon.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Spybot - Search & Destroy (or related software), uninstall then try reinstalling Spybot - Search & Destroy software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many SDWinLogon.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the SDWinLogon.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
