Does an administrator user account on a computer have complete control over a machine?1 pointSometimesYesN

To address whether an administrator user account on a computer has complete control over the machine, it's crucial to understand the role and permissions associated with administrator accounts.

1. Permissions: Administrator accounts are designed to have elevated privileges, allowing them to install and uninstall software, change system settings, and manage other user accounts. Essentially, they can perform a majority of tasks on the system.

2. Control: While administrator accounts have a high level of control, there are certain limitations imposed primarily for security reasons. For instance, modern operating systems often use features such as User Account Control (UAC) which require additional confirmation for certain actions, even from an administrator account. This is to help prevent malicious activities from affecting the system.

3. Security Features: Some files and processes may be protected and require additional permissions to modify. Additionally, certain system processes run with a different level of security that restricts even administrators from making changes.

In conclusion, while administrator accounts have significant control and are the highest level of user account on a computer, they do not have "complete" control in the sense that there are still safeguards and limitations in place to protect system integrity and security. Therefore, the correct answer would be "Sometimes".
