If you want to boot your computer into Safe mode, you must restart it, press a key on the keyboard -- F8 in most cases -- and then select the Safe Mode option and press Enter. If your keyboard doesn't work, Windows will boot normally and will not enter Safe Mode. You can, however, change the boot settings from Windows so that the computer will go directly to Safe Mode after a restart. In this case, you don't need a keyboard.

Step 1

Mouse over the lower left corner of the Windows screen and right-click when you see the Start tip to display the Power User menu. Choose "Control Panel" from the menu to launch the utility.

Step 2

Click the "System and Security" link and then the "Administrative Tools" link to open the Administrative Tools folder.

Step 3

Double-click the "System Configuration" shortcut to open the System Configuration window.

Step 4

Click the "Boot" tab and then check the "Safe boot" box. Click the "Minimal" radio button under Safe Boot and then "Apply" and "OK" to apply the new settings and close the System Configuration window.

Step 5

Restart your computer and don't touch anything. Windows will boot in safe mode by default.
