How to Boot Windows Faster

run... type msconfig , unselect startup items,sometimes may have too much running in background. starting up programs and shutting them down and you may not know there running.  safe and doesnt delete anything.

A proven silly test to boot faster if your pc has a lot of USB ports is this:
get a bunch of USB thumb drives.
Plug all the flash drives in and once plug and play has stopped and found them all put a 512 meg swap file on them min/max set to 512megs. On one super old slow pc (400MHZ) booted faster than my new I7 win 7 installed PC. RAAAAA!!!!!!! So that pc I had 6 usb thumbs drives making the pc faster.

If your XP or what ever shuts under 16 seconds that means your ok :)

i did fresh xp pro sp2 on dell latitude d600 1.6ghz celeron M which boots in 14.5 sec and shuts down at 12.6 sec both in hibernation mode. (50 sec and 11.2 sec normally)..... Hibernation can work without power source unlike standby. ;)

The new mac operating system, snow leopard can boot up extremely fast (i never times startup) but i did time shut down, it clocked in at 2 seconds. Very good. Stayed at 2 seconds ever since even after ive used it a bunch.

WHAT IS A TWEAK?

This video definitely doesn't give the answer for question that is shown in the title...

My windows 7 system shuts down quickly without tweaks but many tweaks do help increase shutdown speeds.

mine starts up in 15 seconds and shuts down in like 5 seconds. just manage the files or programs u have. dont tweak. you screw it up and you lose most speed. I have a Toshiba Laptop 3 gb ram 320 gb hd Intel Pentium Dual Core 2.00 ghz and it is fine.

my vista business  takes 10 seconds to shutdown and 20 seconds to startup
