The correct answer is: D. All of above
Safe mode is a diagnostic mode for Microsoft Windows that starts your computer with a limited set of files and drivers. This helps you troubleshoot problems that might prevent your computer from starting or running correctly.
In safe mode, Windows loads only the basic drivers and services that are required to start your computer. This includes the keyboard driver, mouse driver, and VGA driver.
The keyboard driver is a software program that allows your computer to communicate with your keyboard. The mouse driver is a software program that allows your computer to communicate with your mouse. The VGA driver is a software program that allows your computer to communicate with your video card.
If you are having problems with your computer, you can try starting your computer in safe mode to see if the problem persists. If the problem does not persist in safe mode, then you know that the problem is caused by a driver or service that is loaded when Windows starts normally. You can then try to identify and disable the problematic driver or service.
To start your computer in safe mode, follow these steps:
- Restart your computer.
- As your computer restarts, press the F8 key repeatedly.
- When the Windows Advanced Boot Options menu appears, use the arrow keys to select Safe Mode and press Enter.
- Windows will start in safe mode.
To exit safe mode, restart your computer and press the F8 key repeatedly. When the Windows Advanced Boot Options menu appears, use the arrow keys to select Normal Startup and press Enter.
