In case of Vista and an older machine with XP it almost takes 30 seconds for the PC to boot up plus another minute for the Windows operating system to boot. The reason why we speak about this is because sometimes you need to reboot Windows say new software is installed where you don’t need to restart the BIOS. Normally the reboot happens for both which is technically called “cold boot” rather that “warm boot”.

Now we have a trick that works on both Vista and XP in order to get a “warm boot” thus by saving 30 seconds per cycle.

How do we do it?

Hold the SHIFT key when invoking the restart.

Windows Vista: Select Start, and then hover over the right arrow that is to the right of the padlock icon until the pop-up menu appears that contains “restart” as one of its choices. Hold down the SHIFT key while clicking on the “restart” choice.

Windows XP: Select Start. Select “Shut Down…” Change the drop-down combo box under “What do you want the computer to do?” to “Restart”. Hold down the SHIFT key while clicking on the “OK” button.
