Windows No-Password Login

Of course you still need to assign passwords to users and the administrator account for better security. I'm talking about the use case where it's your personal laptop, and Windows still requires you to type in your password every time it boots up or wake up from sleep.

Easy way to bypass this. Open command prompt, and type in netplwiz. Untick "Users must enter a user name and password to use this computer." Click Apply. It will then ask you to enter your password again. Reboot to take effect. Works for both Windows 7 and 8.1.

Next, go to Control Panel, then Power Options. On the left-side panel, click on "Require a password on wakeup". Select "Don't require a password", then Save Changes.
