That is a tricky question. You first may want to see what programs that you have starting on boot-up and if you really don’t need them, turn them off in the program. Other than doing that, you be careful on what services you turn off. One other point, try not to have too many items on your desktop because the Desktop is basically another folder, except on start up. If you go to an empty spot on the desktop, right click, go to View and uncheck the “Show desktop icons”, your system will be faster in booting up.
