If the system won’t start, you can still view log files. However, this depends on the type of installation and how far the installation got. If it was a clean installation, you should boot to the Windows 7 DVD; select Repair your computer, then access the System Recovery Options menu, and select the Command Prompt. If it was an upgrade that didn’t get far, and if Windows Vista/XP/2000 was previously installed on an NTFS drive, you can boot to the System Recovery Options in Vista, or the Recovery Console from a Windows XP or 2000 CD and view the log files from there.
 If you cannot start the clean installation or upgrade, check the following: • Processor speed and memory size: Verify that your computer meets the minimum requirements for Windows 7.  Make sure you are installing the correct type (32-bit or 64-bit) and version of Windows 7. • Windows type and version: Make sure you are installing the correct type (32-bit or 64-bit) and version of Windows 7 (Starter, Home Premium, and so …

When you complete the clean installation or upgrade, verify that your installation has gone smoothly by testing it. For example, attempt to navigate through Windows, access administrative functions, connect to the Internet, and so on.

 If you have confirmed that Windows is working normally, update the system. Install the latest service pack and additional updates as necessary. It is possible that the service pack was included on your installation media, but if not, download it and install it before going any further. Then, download any other updates that are necessary utilizing the Windows Update feature.

Installations usually go smoothly, but not always. If an installation fails for any reason, or if the installation completed but Windows doesn’t seem to be behaving properly, consider reviewing the log files to find out more about the problem and why it occurred.


The following table refers to variable directory called %WINDIR%. By default, the name of this folder in Windows 7 will be…

By far the most reliable Windows 7 OS is the one installed 'clean', not an update from a previous version of Windows. Differences between versions of Registry entries and DLLs can make an upgraded version less stable. You will lose your installed apps, but you can reinstall from the original source where you got the app, right?

Now that you have decided on the version of Win7 to use and have verified compatibility of hardware, it’s time to install. The Windows 7 installation is more simple than earlier versions of Windows. 
Here we cover the steps involved in a “clean” local installation of Win7. Keep in mind that this type of installation will remove any data currently stored on the computer’s hard drive. The following steps detail an installation of Windows 7 Ultimate. Step 1. Begin the installation from the DVD-ROM. There are two methods to perform a clean install of Windows 7 from DVD: • Install Windows 7 by running the Setup program from within the current version of Wind…

Do you need to install Win7 on a Vista PC? Then, you _can_ update, which in theory will preserve your installed appps; but, it's not guaranteed, and it's far better to do a clean install of WIn7 anyway, as clean installs result in more reliable PCs.

That being said, upgrades are done in essentially the same manner as clean installs. The difference is that all the settings, applications, and user files will ultimately be kept in place if the upgrade is successful. It is recommended that those files and settings are backed up previous to the upgrade. However, before starting the upgrade, you should first check to see if your computer (and operating system) is compatible and if it will survive the process. You can also use the following utilities and websites to do this:

• Windows Upgrade Advisor: This is a website that is accessed by clicking on the Check compatibility online button when you first insert the Windows 7 DVD. Of course, the computer that you want to upgrade needs t…

You can install Win7 from DVD-ROM, from a network, from a USB flash memory drive, from a recovery disc or partition or by restoring a clone image.

Local DVD-ROM: Load the Win7 DVD into your computer's optical drive, boot from it and answer the questions as presented. 
Network install: Install once connected to a network using Windows Deployment Services or Remote Installation Services. Unattend.xml allows unattended installs if you preprogram that XML file for your installation.
Disk image: Apply an entire disc image from external media using apps like Acronis True Image, Norton Ghost or other apps. C:\Windows\System32\Sysprep should be run after applying a clone to alter the Security Identifier (SID) so every PC on a network is unique; if DHCP is not used for automated IP assignment, also change the IP address manually before attaching the PC to your network.
Recovery disc or partition: These contain an image of Windows as if it was installed at the factory. Often the image is on…

Windows 7 includes the Starter version (which limits how many apps can run at once) as well as Home Premium, Professional, Ultimate and Enterprise. Here's a partial reference to versions and features:

The old Aretha Franklin song said it best: “R-E-S-P-E-C-T.” Whether it’s the device you’re servicing (laptop or desktop PC, PDA, printer, monitor, or other peripheral), or the telephone, respect it. Here’s how: • Don’t use customer equipment for personal tasks. Make personal phone calls with your own phone (you do have a cell phone, don’t you?). • Don’t go poking around their hard disk or PDA folders unless it’s necessary to solve the problem. • Don’t “test” the printer by printing personal information. Use your own printer to print your resume or a pinup of your favorite movie star, sports figure, or car. • If you need to reset the resolution on the display for testing, change it back when you’re done. Ditto with any other changes necessary for troubleshooting. • Don’t make the customers sorry they called you or your company for help. Customers who become ex-customers have a way of helping potential customers call somebody else for help.

Passing the A+ Certification exams isn’t an end in itself—it is designed to help start (or advance) your Information Technology (IT) career. In most IT careers, how you deal with customers, whether they’re people you see day after day in your company or clients you might see only once or twice, can have as much of an impact on your career progress as your knowledge of hardware, software, firmware, and operating systems. The following sections will help you master the “soft skills” you need to move up in the computing world. How to Talk to Customers According to pop-culture references like the Dilbert comic strip and innumerable others, computer techs are incapable of relating to “normal” people in either social or professional situations. Unfortunately, these comic stereotypes are based on a lot of real-world data. Here’s how to reverse the stereotype, one customer interaction at a time: • No matter how difficult the problem, maintain a positive attitude and tone of voice—…

Vacuum cleaners are great for cleaning homes and offices, but typical models use plastic parts that can build up harmful static electricity. So, instead of using an ordinary office or home vacuum cleaner to clean a computer, purchase a model especially suited for computer use. Computer-compatible vacuum cleaners have features such as • Small-sized tips and brushes perfect for cleaning keyboards and working around motherboards and add-on cards • Antistatic construction • Hand-held with an adjustable neck for easy use inside a system
Tip Use a vacuum cleaner as an alternative to compressed air whenever possible, especially when working at the client’s site because it’s neater—there’s no flying gunk that can land in awkward places.

Some of these items clean computers and peripherals to help prevent failures and keep systems in top condition. Other items can be used as spares for replacement testing or to replace missing components.

• Compressed air— Cleans gunk out of cases, fans, and power supplies • Keyboard key puller— Safely removes keys to allow effective keyboard cleaning • Computer-rated mini-vacuum cleaner— Cleans gunk out of cases, fans, power supplies, and keyboards and dust off motherboards and add-on cards • Wire cutter and stripper— Used to build network cable • Extra case, card, and drive screws (salvage or new)— Used as spares to replace missing or defective screws • Extra card slot covers (salvage or new)— Used to replace missing covers to maintain proper system cooling • Extra hard disk and motherboard/card jumper blocks (salvage or new)— Used to replace missing or defective jumper blocks when needed to configure devices • Antistatic cleaning wipes • Replacement ATA/IDE (40-wire and 80-wire), flo…
