Structure of talk • • Discusses Windows XP basic concepts customization follow and practice but

Literature • Peter Norton’s Complete Guide to Windows XP by John Peter Mueller, SAMS 2002 • A good book, but expects some background with Windows • Not really hands-on, more conceptual

DOS • In the beginning there was DOS – Command driven – Only one user – Only one task – Could not use more than 640 k of memory • DOS is not dead – Some special files is Windows XP still use DOS command syntax – A floppy disk with DOS can be used to boot the computer.

Microsoft Windows • Operating a computer with windows and mouse was as idea by Apple. • Started life as an application that was started under DOS. This was the setup until Windows 3. 1. • Windows 95 made DOS an application running inside Windows. • Windows 98, Windows 2000 and Windows NT have been other stages in the development.

Windows XP • Is the latest commercially available version. • Comes in two flavors – Home edition • Cheaper – For people who want to play games – For parent who want to install educational software • Limited security – Professional edition • Better, but security still a problem

User interfaces • There are three XP user interfaces for – Restricted user. Can only use the machine but make no changes. This is what we have in the labs. – Power user, can use and make some changes, like, for example, change the keyboard layout – Administrator, can do anything

look at desktop • • icons taskbar start button folder icons – opening leads new window – buttons on window • minimize • maximize / restore • close

mouse operation • primary button – press: select – press and move: normal drag • secondary button – press: context menu • Expanded in Windows XP – press and move: special drag

a window • is a rectangular, bordered element on the windows 98 screen • only one window is active at a time • a window can be resized • a window has a title line • a window has a menu – activate with ALT – select using arrow keys

more about a window • if the contents is too large to fit the size, scroll bars are displayed. • They allow the logical contents to be navigated from the physical window. • if all windows are closed, you see the desktop (this is how I define the desktop) • Use ALT+TAB to move between windows

the task manager • Can be reached from the task bar • Lists tasks that are running on the computer and things you can do with them • Reports and sets – applications – processes – Machine usage • CPU • Page file usage – Network usage.

The start menu • It shows your user name • The left column shows the applications that you use most often (as the machine has noticed ) • The right column has three types of resources – Data resource (by decreasing closeness) – System control (much reduced for restricted users) – Other resources • It is customizable, but not here

Other resources on startup • Help is a unified way to get information about windows XP. • Search is a feature to search information – For files your disk – For other computer – People • Run a command, like one used to do in DOS.

Desktop menu • Arrange icons • Refresh shows a new view of the desktop • Display settings – Choose colors • High color 16 bit per pixel • True color 24 bit per pixel – Choose resolution • Higher resolution may mean lower refresh • You will see smaller icons ah higher resolution

Basic types of files • Normal data files – Program files – Data files, usually with a program attached to it • Directories – Contain other files – Application that is attached is Windows explorer • Shortcut – Contain paths to other files
