In my job, I’m using some Virtual Machines to separate development environments for each customers… and of course, I must log on on each Windows !
You can configure Windows to log on automatically with a specified user:
1. Click Start, type netplwiz (Windows 7) and then press Enter.
In Windows XP, type control userpasswords2 and press Enter.
2. In the User Accounts dialog box, uncheck Users must enter a user name and password to use this computer.
3. Click OK.
4. In the Automatically Log On dialog box, enter the user’s password twice and click OK.
