A. As long as your machine is not a domain controller you can add local users to it and while its possible to use the 'Local users and groups' branch of the system tools root of Computer Management there is a nice quick method available.

  1. Start Control Panel (Start - Settings - Control Panel)
  2. Double click 'Users and Passwords'
  3. Select the Users tab
    Click here to view image
    (Selecting the Advanced tab shows the same information as the Local users and groups branch from Computer Management)
  4. Click Add
  5. Enter a username, password and description and click Next
  6. Enter a password
  7. Select the type of user: normal, restricted or special (e.g. Administrator, Backup operator etc)
  8. Click Finish
