“Ntdll dll” is an acronym for NT Layer DLL. This file is included in a Windows system and it contains NT Kernel functions. A lot of people that experience a crash brought by ntdll.dll errors think that this file might be a virus or a spyware, but it isn’t. However, it can be corrupted by a “trojan” or a virus just like any other computer file.
Usual Causes of “Ntdll.dll” Errors
There are varying reasons but usually, the error is the product of a damaged registry, a Malware infection, or a damaged version of the file itself. Problems between Windows and other programs also give rise to an error in this file.
Some users encounter access violation errors during computer start up. This type of error usually occurs after a program or hardware is installed on the computer. Sometimes, a Ntdll.dll-triggered crash occurs when trying to run old software, such as programs or games.
You can track down an error using Windows Process Explorer. The most common error that can be found when this program is used has the “rtl validate heap” code with it. This error can eat your CPU cycles and slow down your PC.
Can This File Be Deleted?
This file can’t be deleted because it is a Dynamic Link Library (“DLL”) file. It is required by Windows and eliminating this file may result to more errors. This file is used to deliver commands and subroutines on how to operate a task in Microsoft Windows, Windows software, and drivers. A missing DLL file mostly results to more computer errors or bad instructions that generate an error. These can only be fixed if the program is updated or re-installed.
It is best to just leave this file be or let an anti-virus program handle the infections. Some DLL files are shared between different programs and deleting one file might cause one or more programs to malfunction. If you have already deleted the files, then you can download a dll file from the Internet for free or re-install your operating system.
Some users also encounter an error with this file when they’re using an Internet browser. This issue can be resolved by eliminating the add-ons on the browser as well as basic troubleshooting guidelines.
How To Fix Ntdll.dll Errors
These simple guidelines will show you how to resolve faulty modules and other related errors.
Some errors may just be temporary and may be fixed by a reboot. Try restarting your computer and observe if you will still encounter errors.
Try re-installing the program when you notice that the error pop-ups only when you use a specific program. The software program may also require updates or additional files so install the service pack if available.
If the error appears every time you start or while you’re using a browser, try removing the add-ons on the browser one by one and see which add-on triggers the problem. If the error still appears after you disabled the add-ons, try using a different browser.
Deactivate the Data Execution Prevention (DEP) for Explorer.exe. A DEP is an important feature for Windows XP that consists of at least service pack level 2. The DEP can be the cause of system issues because not all hardware and software support it. Errors occur when explorer.exe cannot function properly with the DEP. If you’re still encountering problems even after disabling the DEP, return settings back to the original.
A permanent solution that you can do to stop errors is to disable the User Account Control (UAC) on your computer. UAC alerts the user when changes are going to be made on your pc. It helps in preventing unauthorized deviations in the computer. If you’re not used with tweaking UAC settings, you may disable this permanently.
Outdated drivers sometimes result to errors so update the drivers for the hardware in your computer. If you’re constantly receiving DLL error messages, then check your memory for damages. Testing the memory will identify the issue or at least, make sure that your RAM is not the cause.
If you tried re-installing the individual software and the errors are still there, consider repairing the installation of Windows. This might be a quick fix.
If you’ve tried all of the repair tips above and still encounter errors, consider doing a clean installation that will remove Windows from your computer totally. This means you will have to install Windows in your PC again from scratch. Try this solution only if none of the guidelines above worked and if you’re certain that the error isn’t cause by certain software or programs.
