Unless you have to, it is many times advantageous to œwarm boot, or rather warm reboot, Windows . In a warm reboot, Windows restarts, but the computer doesnt, skipping the whole pre-Windows boot scree/BIOS/startup sequence. You an easily specify a warm boot in both Windows XP and Windows Vista. Just hold down SHIFT on your keyboard before clicking œRestart in Vista, or before clicking OK in the restart dialog in XP. Enjoy the extra 20 seconds!
In the Windows 7 OS... Click the Start menu button on the task bar, then 'Lock' menu button
A cold boot refers to starting a computer that has been powered off. A warm boot is just restarting Windows.
If you restart it in the menu with the mouse or keyboard then it's a "Soft" or normal reboot. If you have to restart with the power button (or restart button on older Macs) on the side of computer case then its a "Hard" reboot.
A hard boot, or cold boot, involves turning on the power with the on/off switch, A soft boot, or warm boot, involves using the operating system to reboot.

Warm boot: not all the processes shut down. It does not take as long for a warm boot and many times users do not have to be off the system. Cold boot: Everything shuts down. There are shutdown scripts which shut down all the processes (so nothing is missed). All users must be off the system. Then, you run the startup script (check for errors). Test the system to make sure the changes you made took effect and there's no problems. Warm boot example: Configurable parameter was changed and the documentation states in order for it to take effect, a warm boot is required. In the documentation for that particular system, a warm boot's criteria will be listed. Cold boot example: Operating system upgrade on the server.
A cold boot is done by completely powering down the computer to off and then starting the computer fresh. A warm boot is restarting the computer without powering the computer off.

AnswerCOLD BOOT (a.k.a. COLD START) - Booting up from power off condition.WARM BOOT (a.k.a. WARM START)- Restarting the computer WITHOUT turning the power off.Shutdown option in the START menu of windows 9x/2K/XP has a "Restart" option: this is a "warm boot".AnswerYou perform a cold boot every time you turn on the power switch of your computer. To "boot" the computer means to start it up and reset the memory and BIOS. Pressing the Ctrl-Alt-Delete keys simultaneously while the computer is running performs a warm boot. You may need to do this if the computer stops responding because of memory problems or the "Blue Screen of Death" appears. The computer needs to be reset before you can continue. If the warm boot fails to restart the computer, you will need to resort to a cold boot by shutting off the power switch, waiting ten seconds and then turning it back on.Answercold booting means ptess ctrl alt del key to restart the system& warm booting means pressing the restart button in the cabinet to restartAnswerCold Boot: When you start from off state or power off and than on by using the power button.

A cold boot always begins with the power off whereas a warm boot does not interrupt the power supply. Although there may not appear to be any difference on the surface (a POST is performed regardless), a cold boot is more reliable as it ensures all hardware is properly reset. When diagnosing hardware issues, it's always best to cold boot the system to ensure consistency. It's also best to let the system rest for at least 30 seconds to allow any residual current to drain before powering up again. Ideally, external peripherals (USB drives, printers, domestic routers, etc) should be turned off as well. Hardware issues are problematic enough without increasing the number of variables you have to contend with.
A Warm Boot
That would be using the menu system to restart the computer. A shut down is a cool boot.
