You can configure computers to log in automatically as a particular user account each time the device reboots. 
To configure automatic login:
1. In the Automatic Login dialog, click the Enable AutoLogin checkbox. Lab Manager will store the password in the LSA Secure store of the device and make the appropriate registry changes.
2. Enter the Domain, Username, and Password that will automatically log in the user.
3. Click Test Login to verify that the login credentials are valid.
4. (Optional) Click Limit Login Count to limit the number of times the user account will automatically login to a particular device. Once this limit is hit, the user will be prompted for their credentials on the login page.
