Disable Require Password After Waking
Windows 7 will make you secure whether you want to be or not. But you can disable require a password after waking from sleep mode with a few clicks. Requiring a password after waking is highly recommended if you work in an office or public area where your privacy and security is important. Any barrier Windows can put between your files and information to the outside world is a benefit to you. But if this is a personal computer in your home, the advantage of this security feature becomes a nuisance.
Disable Require Password
To disable the password request when waking your computer, go to the Start button and type Power. You will see a link for the Power Options. Select Change Power-Saving Settings. Next, Click Require a password on wakeup and then in the ensuing Window select Don't require a password at the bottom. Click Save Changes, and the settings will take effect.

Now when you touch your keyboard or move your mouse to wake up your PC, Windows will reappear as you had left it, without having to login again.
