The "Tela de login," or login screen, is a critical part of the user experience in any operating system, including Windows. While the concept of a login screen is universal, the customization and management of this screen can vary significantly depending on the operating system. In the Windows environment, customizing the login screen involves changing the background, configuring security policies, and managing user accounts. This article will guide you through the process of customizing the Windows login screen using various tools and commands.

Examples:

1. Changing the Login Screen Background:

   Windows 10 and later versions allow users to change the login screen background through the Settings app. Here's how you can do it:

   • Open the Settings app by pressing Win + I.
   • Navigate to Personalization > Lock screen.
   • Under the Background section, choose between Windows spotlight, Picture, or Slideshow.
   • If you select Picture, click on Browse to select an image from your computer.

2. Using Group Policy Editor to Enforce a Specific Background:

   For administrators who need to enforce a specific login screen background across multiple computers, the Group Policy Editor can be used:

   • Press Win + R, type gpedit.msc, and press Enter to open the Group Policy Editor.
   • Navigate to Computer Configuration > Administrative Templates > Control Panel > Personalization.
   • Double-click on Force a specific default lock screen image.
   • Set it to Enabled and specify the path to the image file.

3. Managing User Accounts via Command Prompt:

   You can manage user accounts, which directly affect the login screen, using Command Prompt:

   • To list all user accounts, open Command Prompt and type:

     net user

   • To create a new user account, use:

     net user username password /add

   • To delete a user account, use:

     net user username /delete

4. Configuring Security Policies:

   Security policies can be configured to enhance the login screen's security:

   • Open the Local Security Policy by typing secpol.msc in the Run dialog.
   • Navigate to Local Policies > Security Options.
   • Configure settings such as Interactive logon: Do not display last user name to enhance privacy.

These examples demonstrate how you can customize and manage the Windows login screen using built-in tools and commands. While the concept of a "Tela de login" is universal, the methods and tools used to manage it can vary, and this guide provides a comprehensive overview for the Windows environment.
