Create Users on Windows 7 in a few easy steps.
Creating separate user accounts is important to the security and privacy of your personal computer. Â Once you create another user you should also password protect each account and disable the guest account if you are not using it.
1. Click Start then go to Control Panel.
2. Under Control Panel, click User Accounts and Family Safety.
(Must be Administrator)
3. In User Accounts, hit Add or Remove user accounts.
4. Below the list of the User accounts. Hit create new accounts to add a new account.
Make sure you create a password as well.
Select what type of account you want it to be:  Standard or Administrator.  Remember that a standard user is much safer.  And its perfect if you are making an account that does not require installations and modifications to the operating system.  Standard user account is great for  friends and family.  Be stingy with the administrator account because its susceptible to viruses and misconfigurations.  Only the owner of the system should have an Administrator account.
