Auto-Login Your Windows 7 User Account

• Press the Windows key + R on your keyboard to launch the “Run” dialog box.
• Write in control userpasswords2
• Press Enter. The User Accounts window will display.
• Un-check the option “Users must enter a user name and password to use this computer”
• Click “OK”
• You will then be prompted to enter the current password and confirm it.
• That's all :)

I do not recommend this as anyone can have access to your computer from this moment but it is your option!

If you can't find the check box there than use next steps:

• Press the Windows key + R on your keyboard to launch the “Run” dialog box.
• Type regedit and hit enter to open the Registry Editor
• Then browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\
• Set AutoAdminLogon = 1 (create it if doesn't exist its a string variable)
• Set DefaultUserName = your username
• Set DefaultPassword = your password
