You can disable the password prompt for Windows. This will log you into your account automatically when you turn on your computer. It's a very simple process.
1) Press Windows Key + R to open the "Run" dialog. Enter "netplwiz" and click OK.
2) Uncheck the box that says "Users must enter a user name and password to use this computer." Click OK.
3) Enter your user name and password. Click OK.
Congratulations! Your computer will now log you into your account automatically when you turn it on. If you log out through the Start Menu, then you will need to enter your password to log back in (or you can just restart your computer if you've already saved what you were working on.)
