Double-click Passwords. Click the User Profiles tab. Click the Users Can
Customize Their Preferences And Desktop Settings Option. Click OK and restart
Windows. When Windows reboots, enter your username and password at the logon
prompt and click OK. Log off and repeat for each user profile you create. You
may want to create a Guest login.
Now that you have created the user profiles, you can restore the items that you wanted to appear only on your Desktop and Start Menu by logging on under your name and then moving the items. If there are items that you want to appear under any other User accounts, you would repeat this process under their login names.
If you have security software on your system, re-enable it.
Every time you are finished working, log off by clicking the Start Button, choosing Log Off, and clicking Yes. The next person who uses the computer will have to log on before he or she has access to the system.
