The Vista default logon prompt is nice, but if you have more than a couple of accounts it may be beneficial to change the default logon prompt so that it asks the user to input a username as well as a password. To do this follow these steps.

1. Logon with Admin priviledges.
2. On the start menu type ‘secpol.msc’ into the search/run box, and press enter
3. On the ‘Local Security Policy’ window navigate to ‘Local Policies > Security Options’
4. Double click on the policy ‘Interactive Logon, do not display last user name’
5. Select ‘Enable’ and click ‘Apply’

The next time you logon you will be prompted for both a username and password. Also if you prefer you can enable the option to enforce users to press CTRL+ALT+DEL from the same page, this is found under ‘Interactive Logon: Do not require CTRL+ALT+DEL.
