1. Password Protect The Guest: However, it is not an easy or intuitive task in Windows XP Home. If you open the Control Panel and select User Accounts you will see a list of the users that are able to log on to the system. Selecting your own user account you will see an option that says “Assign Password” or, if a password is already assigned, “Change My Password”. However, if you select the Guest account your options are limited to “Turn On The Guest Account” or “Turn Off The Guest Account” as the case may be.
Windows XP Home uses the Guest account as an integral part of network file and folder sharing. Using Simple File Sharing, when you share out a file or folder it is accessible to anyone who can “see” your computer. If you don’t have other security measures in place such as a firewall that means that users on the public Internet may be able to connect to your share using the Guest account.
Even if you select “Turn Off The Guest Account” it will only be turned off in terms of its ability to log on directly to Windows. In the background, the account will still be functional because Windows XP Home uses the Guest account to authenticate users connecting remotely to shared resources on that machine. It is virtually impossible to truly disable the Guest account and doing so would cause a number of problems on a Windows XP Home computer.
So, in order to protect your system and ensure that not just anybody can connect to your file or folder shares- even when using Simple File Sharing- you need to assign a password to the Guest account. Because Windows XP Home offers no “easy” point and click solution to help you, you will have to use the command prompt. Click on Start, then All Programs, then Accessories and finally select Command Prompt. Once you have the black command prompt window open you will type the following:
· net user guest
You will of course replace the brackets and the word “password” with the password you wish to assign.

    Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as “intruders”) from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.
