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 learn more about DLL files in general see my post What Are DLL Errors?

In some situations, the NTDLL.DLL file may have accidentally been deleted.  If so, you can retrieve the missing file from your Windows Recycle Bin by searching for the file there.

Re-install the Program Causing the NTDLL.DLL Error

If the NTDLL.DLL error is appearing while you are installing a particular program, you should try to re-install that program onto your computer.  If that fails, try a registry cleaner to correct this problem.

Download the Missing NTDLL.DLL File

If you continue to be missing the NTDLL.DLL file, you could download the file from the internet and place it into the proper Windows directory file.  You should use extreme caution if using this method as you may not know if the file can be trusted.  In addition, you need to have some technical skill and knowledge in order to know where to place the NTDLL.DLL file.  Doing this incorrectly could result in additional computer issues.

Update the Drivers for a Particular Device

One reason you may be experiencing the NTDLL error could be related to running a certain device on your computer.  If, for example, you are trying to play a video game, you may need to update your video driver, so take a moment to update your drivers using the Windows Control Panel.

Conduct a System Restore or Rollback

If you suspect that the cause of your NTDLL error is from a recent change made to your computer system, you should perform a system restore or rollback to a previous version of your system where the configuration was functioning properly.

Repair Any Windows Installations

If any of the above troubleshooting suggestions fail, then you should consider performing a Windows start-up repair to ensure that you restore all necessary DLL files.

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.  You will also want to ensure that your computer is running free of any registry errors which can slow down your system.

It is therefore very important that you run periodic registry scans on your computer system to clean your computer from potential errors and to remove corrupt files.
