Windows XP comes in several editions, including Home Edition for home users and Professional Edition for corporate networks. It includes security and networking enhancements over previous versions. There are three main installation strategies: clean install, upgrade, and side-by-side. A clean install wipes the hard drive and installs XP fresh, while an upgrade preserves existing software and settings but can cause instability. Side-by-side installs XP on a separate partition to allow booting between multiple OS versions. The four steps of a clean install are file copy, text mode setup, GUI mode setup, and the Windows welcome process.

Windows defender
Window defender protects a computer system against any form of malware by running in the background of the computer system and gives notification if any suspicious item is found in the syatem for the user to take action. It can also be used by a computer to scan the system if the system has issues e.g becomes slow, switches off when not commanded to, hanging among other things. Windows defender should be updated over time so that it is not outdated and also to improve its performance.
Windows defender is found in the control panel icon, steps of opening are
i. Open control panel and select “windows defender”
ii. While you click on windows defender, the following page appears
a) To update the system click on “update”
b) Real time scanning
c) For the full scan results it will appear in the table as shown below
d) For quick results check the button just before you click on scan. Then the results will appear as shown below.
e) To scan removable device, select “setting” and click on advance
Then check the box just before removing any removable drivers and click save

This document discusses different types of software and how to get software onto a computer. It explains that there are two main types of software: system software and application software. System software includes the operating system and basic utilities, while application software performs more specialized tasks like word processing. The document also discusses how software can be installed from disks or downloaded, and provides examples of useful software programs like Quicken, Picasa, and Evernote.
The document discusses different types of system software, including operating systems and utility programs. It describes three types of operating systems - standalone, server, and embedded/mobile. It also lists 12 key functions of operating systems like starting and shutting down computers, managing programs and memory, and providing security. Finally, it identifies seven common types of utility programs such as file managers, disk cleanups, anti-virus software, and backup/restore utilities, and explains their basic functions.
1. Malware refers to malicious software that can damage programs or systems. Viruses are a type of malware that can replicate itself and spread by modifying other programs.
2. Viruses can infect programs by modifying executable files, documents using macros, or boot sectors. They spread through file sharing and email attachments. Viruses have different phases like dormant, propagation, triggering, and action.
3. Antivirus software uses virus signatures and behavior detection to identify viruses. Infected files may be quarantined to prevent spreading while they are analyzed and removed or restored. More advanced viruses use encryption, polymorphism, and metamorphism to avoid signature detection.
The document provides solutions to 20 common computer problems. For each problem, it lists the steps to troubleshoot and resolve the issue. The problems covered include slow computer speed, system shutting down after short time, printer issues, audio and video playback errors, unresponsive keyboard and mouse, and more. Troubleshooting steps involve checking connections, updating drivers and software, cleaning hardware, and restarting the computer and individual programs.

vulnerabilities to:
• malware
• security exploits.
– Other updates correct errors that aren't related to
security, or enhance functionality.
• Security updates are routinely provided on:
– the second Tuesday of each month, Patch Tuesday,
– but can be provided whenever:
• a new update is urgently required to prevent a newly
discovered or prevalent exploit targeting Windows users.
19
20. Windows Update - download

• Automatic Updates - checks the Windows Update
servers once a day.
– 90% of all PC Users - use automatic updates
– 10% - using the Windows Update web site.
• some updates are:
– not needed
– just take up space.
– cause compatability with some business software,
• so it's important to know what you're downloading.
20
23. Has this Happen to you ?

27. Windows Update Process
• A dialog box will open to display the download and
installation progress.
– If you are prompted for any license agreements, you will
need to accept them.
• Wait for the updates to download and install.
– You CAN minimize Windows Update and perform other
tasks.
• Always RESTART your computer.
– repeat the process until you are sure there aren't any more
critical updates.
• Often, installing a major update like a Service Pack
makes a whole new set of important updates available.
27
28. Firewall – What is it??
• Firewall – defined = software or hardware that checks
information coming from the Internet,
– either blocks or allows it to pass through to your computer,
– depending on your firewall settings.
• can help prevent hackers or malicious
• can also help stop your computer from sending malicious
software to other computers.
• implemented in either hardware (Router) or software,
• Or a combination of both.
28
29. Windows Firewall
• Verify that a Firewall is enabled
– ‘Windows Firewall’ in control Panel.
– Run only 1 Firewall on your computer
– A second Firewall (hardware) in a Router is OK.
• What are some of the things that a firewall can't
prevent?
– E-mail viruses

29
30. Create & Change User Accounts.
• Change User Accounts - create separate accounts for each person using the
computer.
1. each user to have their own:
a. document folders

c. access all files on the computer.
d. make changes to other user accounts.
Limited –
a. prohibited from changing most computer settings
b. prohibited from deleting important files.
30
31. Don't stay logged on as an
administrator
• Why use a standard user account instead of an
administrator account?
• When you are using programs that require
Internet access, such as:
– a web browser
– an e-mail program,
• we recommend that you log on as a standard
user rather than an administrator.
• That's because many viruses and worms can't be
stored and run on your computer unless you're
logged on as an administrator.
31
32. Manage Accounts in Control Panel
Sign in each days as ‘Standard’ account, NOT as ‘Administrator’
32
33. User Accounts
• Note: You can not delete the account for a user that is
currently logged on to the computer.
• The standard account can help protect your computer
• Always login using a Standard Account- never as
“Administrator”
– If you are hacked while on the internet:
• The hacker has limited capabilities..
– you can do almost anything that you can do with an
administrator account,
• Windows will ask you to provide a password for an
administrator account.
33
34. Users at Home
