The Windows® operating system is not working Once you are familiar with the desktop and used to the way the operating system responds to your work routine, you can easily detect if the operating system is not working correctly. For example: ❖ The operating system fails to start after the Starting Windows XP message appears. ❖ The operating system takes a long time to start. ❖ The operating system responds differently from the normal routine. ❖ The screen does not look right. Unless a hardware device has failed, problems usually occur when you change the system in some way such as installing a new program or adding a device. If you experience any of these problems, use the options in the Startup menu to fix the problem. Using Startup options to fix problems If the operating system fails to start properly, you may have to change your system's configuration or verify the startup procedure to fix the problem. To do this, use the options in the Startup menu.
