If you leave you computer for few minutes, it gets locked and then you have to enter password to unlock it. Also when your computer wakes up from sleep (when you choose Sleep instead of shutdown), it asks for a password. If you are a home user then this kind of password security is not required. You can disable this password requirement. Here is how :
- Press the key combination Windows Key + R to open the Run dialog. Type powercfg.cpl in the Run dialog and press Enter.
- In the Power Options window, click on Require a password on wakeup on the left side
- Choose Do’nt require a password from the options and click on Save Changes
Now you do not have to enter any password when your computer wakes up from sleep or when it is locked.
