How to make your system(Windows 7) more secure like Linux

Do you ever think can I make my login secure like Linux ? As Linux asks username and password before logon. Have you thought can it is possible in Windows 7?

So here it is.

1)Open local policy editor by the  help of start button.

2)Click Local policy ->Security policy -> Do not display last user name.(see fig)

3) Now double click on Do not display last user name and a pop comes out click Enabled , then ok.

You'll see the effect from the next logon.

I hope you'll like it.
