What are DefragglerShell64.dll Error Messages?


Dynamic Link Library DefragglerShell64.dll Errors

DefragglerShell64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like DefragglerShell64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Defraggler) could share the same DefragglerShell64.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 DefragglerShell64.dll is attempted to be loaded either when Defraggler is starting up, or in some cases already running. Some of the most common DefragglerShell64.dll errors include:

Your DefragglerShell64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Defraggler), or deleted by a malware infection. Furthermore, DefragglerShell64.dll file corruption could be caused from a power outage when loading Defraggler, system crash while loading DefragglerShell64.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.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your DefragglerShell64.dll issue. These troubleshooting steps are listed in the recommended order of execution.

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 DefragglerShell64.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

If Windows Update failed to resolve the DefragglerShell64.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your DefragglerShell64.dll File (Caution: Advanced)
