We had no winners for our March 2008 Reader Challenge. Although we received many correct answers, those messages lacked the senders' names, addresses, and phone numbers. If we can't send you a prize, your message doesn't go into the pool from which we select winners.

How To (Correctly) Enter the April 2008 Reader Challenge

Solve this month's Vista Update challenge, and you might win a prize! Email your solution (don't use an attachment) to challenge@windowsitpro.com by April 11, 2008 but before you do so, make sure you do the following:

Include your full name, street mailing address (no P.O. Boxes), and a telephone number.

(Without that information, we can't send you a prize if you win, so your answer is eliminated, even if it’s correct.)

I choose winners at random from the pool of correct entries. I’m a sucker for humor and originality, and a cleverly written correct answer gets an extra chance. Because I receive so many entries each month, I can't reply to respondents, and I never respond to a request for an email receipt. Look for the solutions to this month's problem at http://www.windowsitpro.com/articles/index.cfm?articleid=98774 on April 15, 2008.

The April 2008 Challenge

I receive quite a bit of email from readers who are trying to repair their Windows Vista OS, and find they can't log on with the built-in Administrator account. How much do you know about the built-in Administrator account in Vista? Can you answer these questions?

Question #1: The built-in Administrator account is disabled by default in Vista, even when you boot into Safe Mode.

A. True
B. False

Question #2: In Vista, you can enable the built-in Administrator account by which of the following actions?

A. Logging on with a local administrator account and converting that account to the built-in Administrator account.
B. Using the net user command.

Question #3: If you log on to Vista with the built-in Administrator account, User Account Control (UAC) is automatically turned off.

A. True
B. False

Answers:

#1: A – However, Safe Mode lets you log on to the computer with the disabled built-in Administrator account for system recovery if you've demoted, disabled, or deleted the last local administrator account.

#2: B – To accomplish this, open the command window with the Run As Administrator option, and enter
net user administrator /active:yes
To set a password, type
net user administrator
Log off, and when the Welcome Screen appears, the Administrator account is available.

#3: A – The UAC is designed to let ordinary users provide an administrative name and password to perform system tasks. Users with administrative rights are actually logged on with ordinary user credentials, and the UAC provides elevated rights for certain tasks. When the built-in Administrator account is logged on, Vista provides full rights to that account, eliminating the need to provide upgraded rights for protected system tasks.
