This is a registry tweak which actually reduces the startup delay of your WINDOWs from a default 48 Seconds to a limited 4 Seconds.
Thus  reducing the overall startup time to approximately 10 Seconds.

SO here is how the trick goes:

• Click on the start button then press "R" (without quotes) it will take u to Run.
  

•  type "Regedit" (without quotes), and press enter. This will open Registery Editor

• Now look for the key
  

HKEY_LOACAL_MECHINE\SYSTEM\CurrentControlSet\Control\ContentIndex

• Now there find the Key Called "Startup Delay" (without quotes) on the right hand side column.
  

 

• Double Click On It
  

• Now where it says "Base" Change it to "Decimal"
  

• Now its Default Value Is 4800000
  

• Change The Value To 40000
  

Almost done with the tune-up. !!
 

• Now close the Registery Editor and Restart Your Computer
