Hi,



Thank you for posting your query in Microsoft Community.

I understand your concern. Let me help you to fix the issue.



To assist you better, please provide us more information.

• 
  How many user account do you have on your system?
  
• Are you able to log-in to the system?

Meanwhile, let’s try simple troubleshooting steps and check if this helps. I suggest you to remove the username from Credential Manager and check.

• 
  Type credential Manager on the Windows search bar and select Credential Manager.
  
• Now try removing the user name and password by clicking on the credential.

Hope this helps. Let us know the result.

 

XP Boot HDD taken from Failed MB - Get Files?

Just as I suspected... :shadedshu Can't access the Document and Settings for some users on HDD unless I've booted from it and logged in as the user - in this case myself...

Next step boot the old HDD on a different computer in safe mode, with fingers crossed.

 

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.
