How To Fix a Missing NTDLL.DLL File
What is the NTDLL.DLL File?
The NTDLL.DLL is a Windows file that is required on your computer in order for it to function properly. In particular, the NTDLL.DLL file is a Windows module that contains important NT (networking) system functions and is a necessary component of your Windows registry. This system function should not be stopped or removed from your computer and any type of error associated with it should be repaired and fixed.

To avoid many of the problems listed above, it is important that you keep your computer running smoothly. One way of doing this is to ensure that you have the latest files for Windows installed on your computer.
