Second heading, the second bullet

Your link to install the trial version of Windows 7 Enterprise in Windows Virtual PC leads to a landing page of Windows 8 Enterprise. That would be minor, but Windows 8 Enterprise does not work in Windows Virtual PC, so says the Windows Engineering Team. You can find their explanation here: http://blogs.msdn.com/b/b8/archive/2011/09/16/running-windows-8-developer-preview-in-a-virtual-environment.aspx And here is the relevant section of the above referenced doc: "Non-functional: Microsoft Virtual PC (all versions) Microsoft Virtual Server (all versions) Windows 7 XP Mode VMWare Workstation 7.x or older" Also perhaps noteworthy is that the buzz on the web is to use Hyper-V as an alternative to Windows Virtual PC, not VMWare or VirtualBox. (Please advise about which Virtualization software I should switch to.)

Note from the Author or Editor:
Yes, Microsoft redirected the old link to Windows 8. However, it is still accessible here: http://technet.microsoft.com/en-US/evalcenter/dn407368. On page xl in the Software Requirements section, please change the text for the Windows 7 (32-bit) bullet to this: Windows 7 (32-bit). You can download a 90-day trial copy of Windows 7 Enterprise here: http://technet.microsoft.com/en-US/evalcenter/dn407368. Select "32-bit" from the drop down box.

Before the Security section

To cover the following exam objective: 1.0 PC Hardware 1.1 Configure and apply BIOS settings. • Monitoring o Bus speed The following section is to be added on page 67 before the Security section: Bus Speed A bus is simply a circuit that connects one part of the motherboard to another. The more data a bus can handle at one time, the faster it allows information to travel. The speed of the bus, measured in megahertz (MHz), refers to how much data can move across the bus simultaneously. Bus speed usually refers to the speed of the front side bus (FSB), which connects the CPU to the north bridge. FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the north bridge, FSB speed can dramatically affect a computer's performance. Here are some of the other busses found on a motherboard: • The back side bus connects the CPU with the level 2 (L2) cache, also known as secondary or external cache. The processor determines the speed of the back side bus. • The memory bus connects the north bridge to the memory. • The IDE or ATA bus connects the south bridge to the disk drives. • The AGP bus connects the video card to the memory and the CPU. The speed of the AGP bus is usually 66 MHz. • The PCI bus connects PCI slots to the south bridge. On most systems, the speed of the PCI bus is 33 MHz. Also compatible with PCI is PCI Express, which is much faster than PCI but is still compatible with current software and operating systems. PCI Express is likely to replace both PCI and AGP busses. The faster a computer's bus speed, the faster it will operate -- to a point. A fast bus speed cannot make up for a slow processor or chipset. You can monitor the bus speed through the mother board utilities. Additionally, many BIOS programs include tools that monitor the bus speed. For example, Figure 2-11 showed a BIOS page with the speed of the CPU and RAM based on the 133 MHz clock. Some BIOS programs also include the ability to modify the speeds and overclock the system.

Last paragraph on page 209 reads: HTMI resolutions are commonly identified as 1080 and 720. --HDMI 1080 uses a resolution of 1920 × 1080. --HDMI 720 uses a resolution of 1280 × 720. "HTMI resolutions are commonly identified as 1080 and 720." should be changed to "HDMI resolutions are commonly identified as 1080 and 720." to reflect the proper acronym "HDMI" instead of "HTMI".

Note from the Author or Editor:
The feedback is accurate, HTMI should be changed to HDMI.

pg 404 bottom, (exam tip) states for dual boot the newer OS must be installed after the ealier OS, On page 405 3rd paragraph states for dual boot newer OS must be installed first

Note from the Author or Editor:
The word "first" should be replaced with "last" in the first sentence in the third paragraph on page 405. It should read as: The second point to remember when creating a dual-boot system is to install the newer operating system last. This matches the information in the exam tip on page 404.

I believe there is a word or words left out of the paragraph describing how to view known paths. The paragraph currently reads: "You can view the known paths for your system by typing at the prompt and pressing Enter. You’ll see something like this:" I believe the word "path" is missing from the paragraph. If I'm not mistaken, it should read: "You can view the known paths for your system by typing path at the prompt and pressing Enter. You’ll see something like this:"

Note from the Author or Editor:
Please add the word "path" back into the sentence in the third paragraph of the Default Paths topic. It should read like this with the word path bolded: You can view the known paths for your system by typing path at the prompt and pressing Enter.

Before the Shares section

To cover the following exam objective: 4.0 Troubleshooting 4.3 Given a scenario, troubleshoot hard drives and RAID arrays with appropriate tools. • Tools o FORMAT The following section is to be added on page 559 before the Shares section: Troubleshooting Hard Drives and RAID Arrays The previous section covered many of the tools you can use with disks. In addition to knowing what the tools are, you should also know when to use them. • Fdisk. If you need to install an older operating system that doesn’t include built-in tools to create partitions, you can use the fdisk program to create partitions. After the partitions are created, you need to format them. An undocumented feature with fdisk is the fdisk /mbr command that can be used to repair the master boot record on older operating systems. Newer operating systems include the Fixmbr command from the recovery console. • Format. Use this on new disks and RAID arrays to prepare them with either the FAT32 or NTFS file system. If an existing disk is having problems, you can use chkdsk (or Check Disk) to locate bad sectors and fix errors on a disk. If there are many errors and you have a backup of the data, you can do a full format instead of using chkdsk. This will check the disk for bad sectors and mark all bad sectors so they won’t be used. While this step deletes all the data on the disk, you can restore the data from your backup.

Remediate infected system. Update anti-virus software and remove malware from the system. a. Update anti-virus software. Ensure that the antivirus software is up to date. If necessary, you might need to copy definition files from an uninfected system, but you do not want to connect the infected system to the network or to the Internet. b. Use scan and removal techniques. Next, use antivirus tools to scan and remove the malware. In some cases, the malware protects itself when the system is booted normally. If the antivirus software cannot remove the malware, boot into Safe Mode or a preinstallation environment as described earlier.

Before the "Recognizing Other Security Threats" section

To cover the following exam objectives: 4.7 Given a scenario, troubleshoot common security issues with appropriate tools and best practices. • Common symptoms o Spam o Renamed system files o Files disappearing o File permission changes o Hijacked email The following section is to be added on page 897 before the "Recognizing Other Security Threats" section: Troubleshooting Common Security Issues Once you’ve identified security issues or other problems, you need to take action to resolve them. The previous section, “Removing Malware”, provided several steps you can take to remove known malware. However, there are times when you might need to take additional steps to overcome the problems. • Spam. If a user is receiving an excessive amount of spam, you can show the user how to mark email as junk or spam so that it is automatically moved into the junk mail folder. Unsubscribing isn’t always effective. If the user tries to unsubscribe to email sent by an illegal spammer, the unsubscribe request confirms the email address to the spammer. The result is more spam for the user. • Renamed system files. If malware renames system files, you need to either restore the original file, or rename it. You can also use the sfc /scannow command described in Chapter 14 to verify and repair all system files. • Files disappearing. If files are disappearing, you need to first take steps to remove all malware on your system. Once you do, you can restore the files. • File permission changes. Some malware attempts to protect itself by modifying permissions. For example, it might give itself full permission and block other access including the ability to delete it. One way you can resolve this is by booting into Safe Mode with the administrator account. You’ll then be able to restore the permissions from within Safe Mode. • Hijacked email. A hijacked email account is one that is being used by an unauthorized person or by malware. In most cases, the attacker discovers the original password and starts using the email to send spam or malicious email to others. Users are typically informed by their friends that they are receiving spam from the hijacked account. The solution is to change the password of the account to something different and use a strong, complex password.
