How to turn on automatic logon in Windows - Windows 10

Summary

This article describes how to configure Windows to automate the logon process by storing your password and other pertinent information in the registry database. By using this feature, other users can start your computer and use the account that you establish to automatically log on. 

Important The autologon feature is provided as a convenience. However, this feature may be a security risk. If you set a computer for autologon, anyone who can physically obtain access to the computer can gain access to all the computer's contents, including any networks it is connected to. Additionally, when autologon is turned on, the password is stored in the registry in plain text. The specific registry key that stores this value can be remotely read by the Authenticated Users group. This setting is recommended only for cases in which the computer is physically secured and steps have been taken to make sure that untrusted users cannot remotely access the registry.

Use Registry Editor to turn on automatic logon

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
