WindowsWindows 95, 98, 2000, ME, NT, XP? Desktop and icons Task bar Start button Programs


Starting your computerBefore starting your computer make sure you do not have a diskette in your A drive To start your computer just turn on the power switch or power bar (the computer will take a few minutes to go through its initialization procedure and you will eventually see your desktop and icons) If this does not happen check that your monitor (i.e. screen ) is on.


Starting your computer, cont.If computer was shut improperly, you may see a screen saying Windows would like to check your files for errors. It may then say it has found an error and ask if it should fix the error. You will probably want to tell it to fix the error and skip the undo disk and next time try to do a proper shutdown


Shutting down your computerWindows is very finicky about being shut down properly (do not just shut the power off) Move your cursor to start button and click Click on the radio button beside Shut down Click on OK button WAIT (Windows will go through an elaborate process of making sure all programs are shut down. You will then see a Windows screen and eventually a black screen with the words “It’s now safe to turn off your computer”)


Shutting down your computer, cont.You may now turn off the power button/bar. In some cases when Windows cannot finish it’s shutdown sequence, your may have to shut down by restarting or shutting off the power before Windows is ready.


Restarting your computerSometimes your computer will start doing funny things or your mouse will stop working Try ALT + CTL + DELETE If you see a program is not responding, you can try to highlight that program and press the “End Task” button. If nothing happens try ALT + CTL + DELETE again. This will restart your computer


Restarting your computer, cont.If your mouse is working you can click on Start button, click on Shutdown but click on the radio button beside Restart and your computer will restart Useful if your modem stops functioning.

Menu items common to most Windows programsFile (includes New file, open file, save and print functions) Edit (includes Find and Cut, Copy and Paste) View (allows you to change the look of screen by adding and subtracting bars like tool bar) Tools (most programs but program specific) Window (allows you arrange windows and choose between different files) Help used to give help in program’s functions and gives version no. for troubleshooting purposes


Cut/Copy and PastePlace your cursor at the beginning of the text you would like to cut or copy, click with left-hand button keeping the button down. Move the cursor to right to highlight the section or words you want to copy (move cursor down to get whole paragraph or page) When the text you wanted to copy or move is highlighted, let go of the mouse button If you highlight too much text, do not let go of the button but adjust the cursor until you have the right amount of text. If you let go, start over by clicking anywhere that is not a link and start over.


Cut/Copy and Paste, cont.Move cursor to Edit in Menu bar and move down the drop down menu until you reach “Cut” or “Copy” and click (“Cut” will remove the text and “Copy” will leave it where it is) Move the cursor to the area of the document or file where you would like to put the text and click making sure the blinking cursor is where you want the text to be Move cursor to Edit in Menu bar and move down drop down menu until you reach Paste and click
