Once you have created regular user accounts, the default Administrator account vanishes from the Welcome screen, which you see when the computer starts up. Press Ctrl-Alt-Delete twice at the Welcome screen to retrieve the standard logon dialog. You can log on as Administrator from here. To switch among accounts, just click the Log Off button on the Start menu. You'll then see the Log Off Windows dialog box. Click the Switch User button, and you'll be taken to the Welcome screen where you can select and log on to other accounts.
All systems initialize in more or less the same way. During the power on self-test mentioned earlier, the BIOS checks the hardware devices and counts the system memory. Out of all of the different types of system memory, the random access memory, better known as RAM, takes the longest to be counted. Counting the RAM takes time, and on a machine that has large amounts of RAM, this calculation can take several seconds. For example, a machine that has 512MB of RAM may take up to 3 seconds just to count the memory. On top of the RAM counting, a few other tests need to be done because your computer wants to make sure that all of the hardware in your computer is working properly. All of these system tests are not needed every time you boot, and can be turned off to save time. Most BIOS's offer a feature called quick boot. This feature will allow the user to turn off these tests. Other BIOSs only allow you to turn off the memory check, which will still cut down on a lot of time....
