[h=3]Using the Search Companion Depending on what option you choose, you're presented with various ways to conduct your search.
Let's say you choose to search

for a particular file. The Search Companion prompts you with questions to help you refine your search. It's helpful if you can remember something about the missing file such as all or part of the filename, file type, when you last worked with the file, a word or phrase in the file, or what drive it's on, etc. The more criteria contained in your search, the more refined the search becomes.

[h=3]Using the Search Companion (Continued)

• Once you click Search, the Search Companion tells you what it's searching.
• Your search results display in the white space.
• The Search Companion tells you when the search is complete and prompts you with more Search options.

Finding a file can take seconds, minutes or much, much longer depending on the type of search and where you look. If you don't find the file or folder you're looking for on the first try, type in a different name and/or location.

To quickly review files listed in your search results, hover your mouse pointer over the filename. A yellow pop-up window displays, telling you its location, the file type, and size. Double-click the file to open it.

Managing User Accounts :11

[h=3]Understanding User Accounts A user is someone who uses a computer. A user account defines what a user can do using Windows XP. In Windows XP, there are three types of user accounts.

1. Administrator account. The administrator can do everything with the computer and can go anything he or she desires - essentially giving them control over the entire computer, including other accounts. The administrator account can never be disabled or deleted.
2. Standard account. Users with standard accounts can install programs and hardware, change pictures and related personal data, and create, change, or remove his or her password.
3. Guest account. The guest account doesn't require a password, can't add or remove programs from the computer, and is disabled by default. This account type is great for kids or students.

[h=5]The following features are especially helpful for users who have difficulty using the keyboard.

StickyKeys. Enable StickKeys so you don't have to hold down several keys at once on the keyboard.

Once you enable or disable these, you can use them by pressing the Shift key five times in a row.

Filterkeys. Enable FilterKeys to ignore brief or repeated keystrokes. To use FilterKeys, click the Use Filterkeys checkbox and click the Settings button to adjust your personal settings.
