In the previous tip, we talked about running your computer with a 'restrictive user account' that doesn't have administrator privileges. The only problem with running your computer this way, you will soon discover that there will be times that you need these rights to perform certain operations.
To do this, you can use the 'Run As' command, to perform administrator tasks even if you're logged in with a restrictive user account. To access this feature, right-click any program icon and select 'Run as...". A security dialog will display, click 'The following user' radio button, then enter the administrator usrename and password.
For more information see the following Microsoft Knowledge base article: 'How to enable and use the "Run As" command when running programs in Windows' (294676).
