The MCAS: Windows Vista for the Business Worker exam is designed for the professionals who have hands-on experience using Windows Vista for at least one year. The professionals should be very productive, collaborative, and efficient in using the Windows Vista technology.

This exam prepares you for job roles that require knowledge and use of the Windows Vista technologies to complete business-related tasks, such as managing mobile and remote computing, software, disks, and devices, and also managing files and folders.

In the previous post of “Windows Automatic Updates“, I have talked about Windows Automatic Updates and their use. In this post I will be discussing about configuring the Windows Update settings.

The steps to configure the Windows Update settings are as follows:

1. Open the Control Panel window, and click Security.



2. In the Security window, click Windows Update.



3. In the left pane of the Windows Update window, click Change settings.



4. The Change settings dialog box will appear. Select the update options, and click on the OK button.

Windows Automatic Updates include the latest security and critical updates and service packs. These updates ensure that the computer is protected against the latest viruses and other security threats. Through Automatic Updates, Windows automatically downloads the latest updates on the computer on a pre-determined schedule.

Windows Update can be setup to automatically update your PC by automatically downloading and installing both Important updates and Recommended updates in Windows Vista. Windows Update is a free service built into Windows. It is designed to help you keep your PC more secure, reliable, compatible with devices, and able to run new features that may enhance your experience. With Windows Update, you can easily get the following:

1. The latest security updates to protect against malware and other potentially unwanted software
2. Updates that improve reliability and performance
3. Upgrades to Windows features
4. Drivers from Microsoft partners

In the forthcoming posts, I’ll be discussing about configuring the Windows Update settings.

For security reasons, a firewall is essential for a computer. It prevents any malicious program from running. It is a set of related programs configured to protect private networks connected to the Internet from intrusion. It regulates the network traffic between different computer networks. It permits or denies the transmission of a network packet to its destination based on a set of rules.

Sometimes there is a need to allow certain programs to pass through the firewall. In this post, the procedure to configure firewall to allow certain programs is discussed.

The steps for configuring firewall access for specific programs are as follows:

1. Open the Control Panel window, and then click Security.



2. In the Security window, click Windows Firewall.



3. In the left pane of the dialog box, click Allow a program through Windows Firewall.



4. The Windows Firewall Settings dialog box will appear with the Exceptions tab selected. Check or uncheck the programs according to the requirement, and then click the OK button.

Note: If you need to include programs that are not listed, click the Add program button. Click on the program you want or browse the location of the program’s exe file if it is not in the list, and then click OK. The program you have included can now pass through the firewall and can access external networks or the Internet.

In the next post, I will discuss about Windows Automatic Updates.

Malware is a combination of the terms malicious and software. It refers to a variety of hostile programs, such as a virus or a Trojan horse, designed to damage or disrupt a computer. It gathers information about a computer without the user’s permission or knowledge.

Adware is software that automatically downloads and display advertisements in the Web browser without user permission. When a user visits a site or downloads software, sometimes a hidden adware software is also downloaded to display advertisement automatically. This can be quite irritating to user. Some adware can also be spyware.

Spyware is software that gathers information about a user without his knowledge. Spyware can get into a computer when the user downloads software from the Internet. Spyware can search the contents of a hard disk, address book of an e-mail, or any information about the computer, and transmits the information to the advertisers or other interested parties.

Windows Defender is a software product from Microsoft to prevent, remove and quarantine spyware in Microsoft Windows. It was formerly known as Microsoft AntiSpyware. It is included and enabled by default in Windows Vista and Windows 7, and is available as a free download for Windows XP and Windows Server 2003.

Windows Defender features system scan capabilities similar to other free products on the market, and includes a number of real-time security agents that monitor several common areas of Windows for changes which may be caused by spyware. It also includes the ability to easily remove ActiveX applications that are installed. If it detects anything suspicious, an alert will appear on the screen.

BitLocker Drive Encryption is a full disk encryption feature included with the Ultimate and Enterprise editions of Microsoft’s Windows Vista and Windows 7 desktop operating systems, as well as the Windows Server 2008 and Windows Server 2008 R2 server platforms. It is used to protect all files stored on the drive Windows is installed on. It encrypts the entire system drive and helps block hackers from accessing the system files they rely on to discover user passwords. By default it uses the AES encryption algorithm in CBC mode with a 128 bit key, combined with the Elephant diffuser for additional disk encryption specific security not provided by AES. BitLocker also prevents hackers from accessing the hard disk by removing it from a computer and installing it on a different computer.

BitLocker is available only in the Enterprise and Ultimate editions of Windows Vista and Windows 7. Users of other versions of Windows Vista could use a 3rd party encryption program to satisfy the need for full drive encryption.
