Speedup boot up sequence by defragmenting all key boot files

Open Registry by going to START-RUN and typing REGEDIT. Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction. In right
hand panel look for Enable. Right click on it and set it 'Y' for enable.
This is the way I have it set on my computer. This will help speedup boot
time.
