I am on a corporate network, and I login to my Windows 7 box using a network domain account. If my computer was locked (ctrl+alt+del -> lock), and a network admin changed my password, would I be able to simply unlock the machine using the new password, or would I have to fully log off (i.e. close all the running applications), and then login with the new password? Thanks.

You don’t need to fully log off. You can do as the steps below: 1 Press Ctrl+Alt+Delete, then click The Other User. 2 Enter your domain name and your new password.

Simply login as you do.
