Windows 7 and Windows Vista have an option to select the number of processors that can use for the booting process. It will be one by default. So if you are using a dual, quad processors (most of the recent PCs have dual processors atleast), you can increase the booting speed by using more processors. To set this, follow the simple steps given below
Open Run windows (Win+R)
Type MSConfig and Press Enter
Go to Boot Tab
Click on Advanced options button
Check the Number of Processors checkbox and select the maximum value from the drop down
Click OK and then Apply and then Click OK again.
Reboot to save the changes made. Update: I just slapped myself on my face for falling for this trick. This doesn’t work. Click here to know why.
