For SharePoint 2013 administrators, managing user properties like usernames, display names, and email addresses can be done effectively using PowerShell. The `Set-SPUser` cmdlet is particularly useful for these tasks.

Here’s an example of the command tailored for SharePoint 2013:

Set-SPUser -Identity 'yourmachine\UserName' -DisplayName 'User Name' -Email 'username@yourmachine.com' -Web http://yourmachine

Key Parameters Explained:
1. `-Identity`: Identifies the user account you wish to modify. Replace `yourmachine\UserName` with the actual details.
2. `-DisplayName`: Sets or updates the display name visible in SharePoint 2013 interfaces.
3. `-Email`: Updates the email address associated with the user for proper communication.
4. `-Web`: Specifies the SharePoint 2013 site URL where the user’s properties are updated.

Important Notes for SharePoint 2013:
– Compatibility: SharePoint 2013 relies on PowerShell 2.0 or 3.0. Ensure your environment is set up accordingly.
– Permissions: The user running the command must have the necessary administrative privileges for the SharePoint site.
– Testing: Always test commands in a development or staging environment before applying them in production.

PowerShell continues to be an invaluable tool for managing SharePoint 2013 efficiently. With commands like `Set-SPUser`, administrators can streamline routine updates and maintain a well-organized environment.
