What are UnattendProvider.dll Error Messages?


Dynamic Link Library UnattendProvider.dll Errors

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

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

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

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

Step 2: If recently installed VirtualBox (or related software), uninstall then try reinstalling VirtualBox software.

You can uninstall VirtualBox software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for VirtualBox 6.0.14 and click "Uninstall"

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

  1. Hit the Windows Start button
  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 UnattendProvider.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve UnattendProvider.dll problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download UnattendProvider.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying UnattendProvider.dll to your appropriate Windows system directory. Oracle Corporation typically does not release VirtualBox DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing UnattendProvider.dll and all other DLL files for VirtualBox. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
