Run as Administrator in Windows XP

How to Use the RUN AS Command to Start a Program as an Administrator

As an administrator, you can use the run as command to start a program. To do so:

Enable Administrator Account during Log On

We can easily get the administrator account by just pressing Ctrl+Alt+Delete during log on screen where we see different accounts. But If we want to see the Administrator account along with all the other user accounts during log on we need to follow the following steps: 

1. Open command prompt by typing the command CMD in Run window

2. Type net user Administrator /active:yes at the prompt C:\> and press enter then we will see the administrator account in addition to other user accounts.

This works even for windows 7.
