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

Literature Peter Nortons 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 640k 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

Windows explorer Can be started on its own, in the programs/accessories startup –Folder section –Drive section (not visible here) –Network section (not visible here) –Recycle bin

Delete files to delete file, right click on the item, select delete that moves it in the recycling bin then click right on the recycling bin and remove it from there Otherwise they are still around!
