Difficulty: EasyWindows Security Settings and User Account Control

A user logged in with a standard user account on a Windows workstation attempts to run a software installer that modifies system files. Before the installation can start, a User Account Control (UAC) dialog box appears requesting administrator credentials. Which of the following explains why this prompt was displayed?

  1. Standard user accounts require privilege elevation and administrative credentials to make changes that affect system configurations.Answer
  2. B
    The user account lacks explicit NTFS Full Control permissions on the temporary installation folder.
  3. C
    The Windows Home edition installed on the workstation disables background installation tasks by default.
  4. D
    The application architecture is incompatible with the 64-bit operating system version.

Answer

Standard user accounts require privilege elevation and administrative credentials to make changes that affect system configurations.
User Account Control (UAC) prevents unauthorized system-wide changes by requiring standard users to enter administrator credentials before executing applications or installer packages that modify operating system settings.

Step-by-Step Solution

1
Identify the user's role and requested action.
The user has a standard account and is trying to run an installer that alters system-wide files.
Standard user accounts operate with limited privileges to prevent unauthorized system modifications.
2
Evaluate how User Account Control (UAC) handles standard user privilege boundaries.
UAC triggers a credential prompt requiring an administrator password to proceed with the action.
This behavior ensures that administrative consent or credentials are provided before system changes occur.
