This dll file is possibly the most important file to the operating system and the most disastrous if it becomes corrupted. The damage of this file can cause a variety of errors pertaining to, memory, hard disk failures and other serious problems. This damage is commonly caused by well-designed viruses that manage to bypass Windows’ native protection of its critical system files. It may also be cause by bad software installation. If you have just installed new software you should uninstall it immediately and hope everything works fine. If this fails, your best bet is to completely reinstall Windows as this problem is not usually fixed by the stand download and register dll files procedure.
