Windows 10: Advanced Startup repair User account lost

I used an old image back up to restore the computer but now the Computer does not start with Windows 10 and going through the advanced options for repair I cannot access any of them because the system has lost my account and it only shows “user”. I tried all different passwords but none of them is acceptable, obviously because there is no user account therefore the system goes endlessly through the loop of unable to start, start repair, diagnosing the system and still not being very able to start. I have tried starting the system from a USB with repair from Microsoft but again it refuses to st

Lost User Account

Hi,

Thank you for posting your query at Microsoft community.

If you have the Windows 10 installation DVD, I would suggest you to enable the default administrator and then try creating a new user account with administrative privileges.

Boot the computer into Safe mode then, open Command Prompt and enable Built in Administrator.

Follow the below steps to enable Built in Administrator:

• Open Command Prompt from Windows Recovery Environment.
• Copy and paste the below command and press Enter.

net user administrator /active:yes

3. Close the Command Prompt.

4. Try to login though Built in Administrator and create a new user account with Administrator rights.

To start the computer in safe mode. Type Settings in the search tab> under Recovery> Advanced Options>Restart Now>Troubleshoot>Advanced Options>Startup Settings>Restart>select 4

After that you may follow the steps to transfer the data as suggested in the previous post. Please do not forget to disable the default account once you are done troubleshooting. Just follow the same stepsnet user
administrator /active:no





Please let us know if it helps or if you need further assistance. We will be glad to help.

 

Lost User Account

After upgrading from Window 7 to 10, I lost my wife's User Account got messed up, using my email address and login password, with no ability to change them. I received the reply below, but still have problems:

I understand the inconvenience you are facing with user accounts, we will help you to resolve this issue.



I would like to inform that there can be only one Microsoft user account on one device, and that might be the reason you are unable to change the email address for the user account.



I suggest you to create a new account (Local account) on your computer and transfer the content to newly created user account.



Step 1: Creating a new user account

• Type cmd in the Search bar form the desktop.
• Now, Right-click on cmd.exe from the result and select Run As Administrator.
• User Account Control or UAC dialog box will appear, click on Yes.
• Type net user username password /add
  
  [Replace ‘username’ and ‘password’ with your desired username and password]

Step 2. Copying old files to newly created User Profile

• Go to C:\Users\(Your-Corrupted-
• Copy all files except three files:

• 
  NtUser.dat
  
• 
  NtUser.ini
  
• 
  NtUser.log
  

3. Go to C:\Users\(New-User-Profile-

4. Paste all those copied files here.

I tried to create a new user account as in Step 1, but when I put in the command as written above, I kept getting messages about correct syntax for the command. No matter what I tried, it wouldn't work. I
then tried to set up a new account using the Settings/Accounts/"Add someone else to this PC" menu. I set up the account, but no folder was created under C:\Users\. I tried adding a folder using the new accounts user name and transferred the files from the
other account. When I tried to log in, I received the same error message. I am at a loss as to how to get back the user account with the correct username, email address, and password. HELP!!!
