Fix Corrupt Windows User Profile : How to

In Windows when a user is created a profile generated. This profile acts as identity and place holder where all information for the user can be stored and can be used to identify him or her again. Many a times because of unusual events like Windows Crash, permission issues, Transfer of Windows Account etc the user profile get corrupted which either leaves the existing user account completely unusable or windows create a fresh account again sometimes and user will lose all its settings like desktop backgrounds, screen savers, pointer preferences, sound settings, and other features.

Before we start learning how we fix any corrupt account make sure you have a an account which either is admin or is  admin privileged.

All the Windows User Profiles are located under C:\Users\UserName which contains all our settings. Now go to your account and unhide hidden folders and uncheck Hide Protected operating system files. You would see three files NTUSER.DAT, NTUSER.dat.log and ntuser.ini which you will need to be careful about.

User Profile Folder

  • Login with your admin account and  create new account.
  • Now identify which user profile is corrupted and  go to that folder which will be like C:\Users\UserName
  • Unhide Folders / Files and display system files
  • Copy everything from this folder  except three files NTUSER.DAT, NTUSER.dat.log and ntuser.ini
  • Go to new account folder located under C:\users and paste all the files you copied in above step.
  • Logoff and login to the new account to confirm.
  • Delete the old account.

User Profile System Files

This should fix your problems. Remember many a times because of some bug you might see Windows giving you a brand new profile but if you logoff and try logging in again you would see the issues getting fixed.

There is another alternative called as Reprofiler a software which can also help you in fix these issues by remapping users to their profiles, fixing registry settings and permissions which is required to fix any corrupt windows account.

Reprofile application

It displays all the user accounts above and all the windows users folder below. Now to fix it or map to any other account you can just select first a user name above and a folder below and then hit Assign. This will make sure it copies and assigns proper settings. You can also remove / detach folders which is useful when it comes to erase the data. Download Reprofiler from here / Alternative


  1. Hi Ashish,

    Nice little writeup on profile fixes. I’ve lost my ability to open ANY of the listed users on startup. I’d like to try using Reprofiler, but do not know how I can install/run it. Can it be done using a command prompt at bootup, or do I need to try opening Windows in safe mode and install/run it from there? I visited the ReProfiler website,but saw no information there. Thanks for any advice you can provide!

  2. Hi Bob, There is no command prompt option and you can use it in safe mode but thats really not necessary. All you might need is Admin privilage for your account.

    Not sure what you mean by install/runn but if you mean how to use it, then all you need is just select user on top and map it to the folder path below and you will be done.


  3. Thanks, Ashish. I can’t open windows using any of the existing profiles, that is why I mentioned using safe mode as that at least got me into windows (as admin, I believe). And that was what I meant by install/run – it is an executable, correct? I had hoped I could do it via command prompt but wasn’t sure. So I need to get windows open and then run the executable file…thanks again, I will try that! This whole mess began when I somehow got some windows 7 files on the same partition as Vista, so that it shows a double boot option, both on the C: drive. I was following instructions from MS regarding reverting to Vista, and one step involved renaming and moving the user profiles around. I tried simply reversing the steps I’d performed, but my profiles did not become usable. Will try getting in as admin and see what happens. Thanks again!

  4. Hi Ashish,

    I did manage to get Vista working again – half the problem was in how I’d moved my user files folder back to the original location – apparently I moved it as a folder within a folder. Once I got ME working right, I was able to run the ReProfiler and get the rest of the family back up and running. Now, my next challenge will be to remove my small Win7 partition and convert the whole thing to Win7 64bit with the help of PCmover (I hope!)
    Thanks again for your help!

  5. Hi,
