5.

Contoso, Inc. recently hired you as a system administrator for its small network of ten

Windows XP Professional computers. After performing a security audit, you realize that

two of the computers have not yet had Service Pack 2 for Windows XP installed. You

use Internet Explorer to visit the Windows Update site, and are notified that the com-

puters were activated with invalid product keys. Contoso has purchased additional

valid product keys for these computers. What is the quickest way to resolve the prob-

lem to allow Service Pack 2 to be installed? Choose the correct answer.

A.

Insert the Windows XP Professional CD-ROM, and then restart the computer. Per-

form an upgrade installation over the existing Windows XP system directory. When

prompted, provide the new valid product key, and then install Service Pack 2.

B.

Back up all files and settings on each computer. Insert the Windows XP Profes-

sional CD-ROM, and then restart the computer. Perform a new installation of Win-

dows XP by reformatting the hard disk. When prompted, provide the new valid

product key, and then install Service Pack 2. Restore the files and settings from the

backup.

C.

Change the HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\Current

Version\WPAEvents\OOBETimer Registry value, and then run the Msoobe.exe

tool to reset the product activation key. Then install Service Pack 2.

D.

Right-click My Computer and then click Properties. Click the Advanced tab and

click the Environment Variables button. Select the PRODUCT_KEY variable, and

then click Edit to specify a new product activation key. Then restart the computer

and install Service Pack 2.
