If you need to run an application with rights of a different user, you can do this easily in Windows 7. This may come handy when you need administrator rights to run a particular application. Instead of logging out and logging back into the administrator account, you can now hold down the (Shift] key while right-clicking on an application and then click on Run as administrator. If you want to run the application as any other user, click on Run as other different user. You'll need to enter the username and password for that account.
