[What is ntuser.dat and Why is it on My Computer? - Tech Junkie](^4^)



This article provides help to solve an issue where profile loading fails when the ntuser.dat or usrclass.dat file is defined as read-only, or the profile user lacks the appropriate permissions for these two .dat files.


This article discusses complete file details, DAT file troubleshooting instructions for problems with ntuser.dat, and a comprehensive set of free downloads for every file version that has been catalogued by our team.




Download Ntuser.dat File Windows 10



Ntuser.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ntuser.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. YouTube Download & Convert) could share the same ntuser.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.


Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when ntuser.dat is attempted to be loaded either when YouTube Download & Convert is starting up, or in some cases already running. Some of the most common ntuser.dat errors include:


Your ntuser.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with YouTube Download & Convert), or deleted by a malware infection. Furthermore, ntuser.dat file corruption could be caused from a power outage when loading YouTube Download & Convert, system crash while loading ntuser.dat, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.


If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate ntuser.dat file version. We maintain a comprehensive database of 100% malware-free ntuser.dat files for every applicable version of YouTube Download & Convert. Please follow the steps below to download and properly replace you file:


CAUTION : We strongly advise against downloading and copying ntuser.dat to your appropriate Windows system directory. CubedLabs typically does not release YouTube Download & Convert DAT files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing ntuser.dat and all other DAT files for YouTube Download & Convert. An incorrectly installed DAT file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.


These ntuser.dat problems are generally caused by Office-related file corruption, or in some cases, if the file has been accidentally or maliciously removed. Ordinarily, installing a new version of the DAT file will repair the problem creating the error. In addition, if your ntuser.dat error was due to a removed malware infection, we recommend running a registry scan to clean up any invalid file path references created by the malicious program.


Most of your ntuser.dat problems should be resolved if the file is placed in the correct file path directory, but it's a good idea to verify it is fixed. You can test the result by running Office application and seeing if the issue still appears.


from my testing, if you successfully log on to a windows 11 machine using a domain account, and then log off and have delprof2 clear out the profiles, the next time that same user tries to log on, the profile will not load correctly and be unusable
