Automatically sign in to your Windows 8 account on system startup
If you want to further reduce the time it takes your Windows 8 system to boot one of the most efficient options will be to automate the login process - this saves you the time you usually spend on wiping away the lock screen and entering your password.
Be careful though! Not having to enter the password at startup leaves your machine vulnerable to direct access by strangers. This should not be done to portable or public machines!
If you choose to do so anyway you need to edit the User Account settings - the fastest way to get there is to point your cursor to the bottom left corner of the screen, right-click and open a Run prompt. Enter netplwiz into it:

Afterwards, the machine will log into the account automatically!
