To help secure your computer, Windows requires a password to unlock the computer when it wakes from sleep. It's a good idea to protect information by using a password, especially if there is confidential information on your computer—but, if you're the only one who uses the computer at home, and you don't want to enter a password every time your computer wakes, you can change this setting.
For information about how to change your password, see Change your Windows password.
Some settings are managed by your system administrator. SeeWhy won't Windows allow me to change a system setting? for more information.
Use one of the following procedures to remove the requirement to enter a password when your computer wakes.
Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.
On the Select a power plan page, in the task pane, click Require a password on wakeup.
If necessary, click Change settings that are currently unavailable.
On the Define power buttons and turn on password protection page, click Don't require a password.
Click Save changes.
On the Select a power plan page, click Change plan settings under the plan that you want to change.
On the Change Settings for the plan page, click Change advanced power settings.
On the Advanced settings tab, under Require a password on wakeup, do one of the following:
If you're using a laptop, click On battery or Plugged in (or both), click the arrow, and then click No.
If you're using a desktop computer, click Setting, click the arrow, and then click No.
