Difficulty: EasyApplication Installation and Configuration Concepts

A user on a corporate network receives an installer package for a new office productivity tool. When the user double-clicks the installer, User Account Control (UAC) prompts for administrative credentials. Why is elevated access required for this installation?

  1. The installer needs permissions to write files to protected system directories such as Program Files.Answer
  2. B
    The application requires a 64-bit operating system architecture to execute.
  3. C
    Windows Home edition does not support the installation of third-party software packages.
  4. D
    The installer must automatically update Windows Control Panel applets before proceeding.

Answer

The installer requires elevated administrative rights because it needs permission to modify protected system locations such as C:\Program Files and system-wide registry hives.
Installing software designed for all users on a computer requires modification of protected system directories (such as C:\Program Files) and global registry keys (HKEY_LOCAL_MACHINE). Standard user accounts lack these permissions, so Windows triggers User Account Control (UAC) to demand administrator credentials before permitting changes.

Step-by-Step Solution

1
Identify the event described in the scenario.
The user is running an application installer that triggers a User Account Control (UAC) administrative credential prompt.
UAC guards system integrity by preventing unauthorized changes to system-wide configurations.
2
Analyze why UAC prompts for administrator credentials during application setup.
System-wide application installations write binaries into protected folders (e.g., C:\Program Files) and modify HKEY_LOCAL_MACHINE registry keys.
Standard user accounts lack write permissions to these protected system resources to ensure security and stability.
