  1. Open the registry editor.
  2. Navigate to the ProfileList registry key. The path is:
  3. HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows NT -> CurrentVersion -> ProfileList
  4. Select the folder under the ProfileList key
  5. On the right side, find the value of the line ProfileImagePath
  6. If the value is present, there is nothing wrong with this user profile folder.
  7. If the value is missing, delete the entire folder.
  8. Repeat the above steps for the other folders in the ProfileList folder.
