Start-up errors, in general, are vital indicators to deep-seated technical issues that needs immediate attention. The Rundll error in Windows is frequently encountered when there is a potentially hazardous malware threat or a full-fledged virus attack.
What is a Rundll Error
The Rundll.exe are key system processes that specify functions used by the operating system to run a range of programs. Most programs share the vast data and code defined in the Dll files that are linked to the Windows Registry and help the OS process a particular program and improve efficiency and access speeds. Dll files, if corrupted or deleted, could cause system problems, most commonly boot-up issues and even serious system crashes.
Fixing a Rundll Error
Not all Rundll errors indicate virus infections, so begin by rebooting your PC to check if this resolves the issue. If a threat does exist, a system refresh may not work, and the key lies in analyzing the source of the problem. There are several approaches to doing this:
1. Remove and Re-install: The first step to resolving a Rundll error is to remove or reinstall the program inducing the error. To do this, open Control Panel and use the Add/Remove Program utility to uninstall the corrupt software completely. Never delete an installed program as this will not uninstall it completely. Reinstall the program and then reboot your PC.
2. Run Antivirus Checks: Running an antivirus program is the best way to remove or fix malware and virus threats. A virus scan can be run regardless of whether the error itself has been fixed after reinstallation of the program causing the error.
3. Windows Registry Editor: A Rundll error that loads right at start-up can be resolved only by deleting the associated process from the Registry. Use the simple instructions below to do this:
a. Click Start and type RegEdit in the Run field to access the Registry Editor.
b. Navigate to the Current Version of the Registry or type “Microsoft/Windows/CurrentVersion/Run” in the search field.
c. Delete the registry keys corresponding to the Dll files of the program that triggered the error.
d. Close RegEdit and reboot.
Exercise caution when choosing to edit your Window Registry as this plays a crucial role in smooth system functioning.
