Windows 7 auto logon
Perhaps you have (like me) configured a Windows box as a media center in your living room. In order to conserve power, I shut the PC down, when not in use. Power up is so fast that I don't see the point in putting it to sleep. Especially when the USB IR receiver is still powered on and i can turn on the PC via remote. When the PC powers on, I don't want to enter the password (since I have disabled Windows Explorer and replaced it with XBMC). This is what you must do to auto log on an user.
Click on Start and then enter the following command in the search box:
netplwiz
Press the ENTER key.
This command will load the Advanced User Accounts Control Panel applet.
In the Users tab, uncheck the box next to Users must enter a user name and password to use this computer.
Click on the Apply button at the bottom of the User Accounts window.
When the Automatically Log On dialog box appears, enter the user name you wish to automatically login to Windows 7 with. Then enter your account password in the two fields where it's asked.
Click the OK button.
Click OK on the User Accounts window to complete the process.
