Hybernate your pc to shutdown it very fast

If you have to shutdown your windows xp for some time then comeback and reboot your pc , then there's a great way to minimize the time taken for shutdown and restart your pc. This is a method called Hybernation. When you Hybernate your pc it saves the state of your pc( which softwares you kept open), and shuts down very quickly. When you comeback and restart your pc it automatically starts the the softwares exactly as you left them while hybernating the pc. This way  it saves alot of time for both shutdown and restarting your pc.
By default, hybernation is not activated in windows xp. To activate it
1. Right click on your desktop.
2. Select "properties".
3.Go to "screen saver" tab.
4. Click The "Power" Button.
5. then go to "hibernate" tab and check the "Enable Hibernation" checkbox. Also check the amount of space it reserves for hibernation.
6.Now, when you are going to turn off your pc, hit the "shift" key and you will see the "hibernate" option in place of "Stand By".
 Remember, if you don't have that much amount of free space  in your windows drive then this feature will fail or make your windows xp awkwardly slow. So, if you have installed windows xp in c drive and your ram is 1 GB, then you must leave 2GB free space for swap memory(2 * size of ram) + amount of space required for hibernation.
