The i81io16.dll file is part of an unknown process. While initially this may be alarming, unknown registry errors are common due to the nature of the dynamic link library (DLL).
The dynamic link library works in the same way a filing cabinet works. Multiple programs have access to all the files in the dynamic link library (DLL). This saves your computer time and space by having them all in one place. The one drawback is the files are more susceptible to damage and accidental deletion. When this happens, registry errors occur.
Computer experts recommend regular registry maintenance. ZookaWare took the challenge and created ZookaWare PC Cleaner. ZookaWare PC Cleaner guarantees 100% registry error removal.
