Remove User Accounts from the Login Screen in Windows XP Lowell Heddings @lowellheddings February 17, 2008, 11:37pm EDT So you login to your computer every single day, but there’s more than one account to choose from either because you got the computer from somebody else, or some software package added a user account that you really don. A user profile is a set of files and folders to store all the personal preferences, app settings, desktop information and other data. If your user profile is corrupted, it can cause unexpected issue with your Windows account, or even lock yourself out of the computer.
