The Windows operating system features a built-in security feature that enables you to lock your computer after a certain period of time and prompt for a password. This option, which is enabled by default, is designed to prevent others from accessing your sensitive personal information. Unfortunately, this can become quite cumbersome over time, especially if your computer never leaves your home. You can disable this feature after making a simple modification to your computer's security settings.
Click on the "Start" menu tab at the lower left portion of the screen and launch the "Control Panel" tab. Double-click on the "System Maintenance" icon and select "Power Options."
Click the "Change Plan Settings" button to modify your computer's power settings. Open the "Change advanced power settings" tab at the top of the screen. Click on the link titled "Change settings that are not currently available." Press the "OK" button when prompted to grant administrative rights.

Press the "+" dialog box next to the "Advanced Settings" option to expand the list of your computer's advanced power settings. Scroll through this list until you reach the option titled "Request a password on wakeup" and click on it. Change the value from "Yes" to "No" and press "Enter" to save your settings. Your computer will no longer lock you out after a certain period of time nor will it prompt you for a password.
