FC0-U71 Applications and Software Practice Question
A user needs to install a new application on a Windows 10 computer but does not have administrative privileges. The application requires writing to the Program Files directory and modifying system registry keys. What will happen when the user attempts to install the application?
⚠ Common exam trap
The trap here is thinking that Windows will automatically find a way to install without admin rights, when in fact it will prompt for credentials or fail.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user will be prompted for administrative credentials via User Account Control.
When a standard user attempts an action that requires administrative privileges, such as writing to Program Files or modifying the registry, Windows triggers a User Account Control prompt asking for administrator credentials. If valid credentials are provided, the action proceeds with elevated rights; otherwise, it is blocked. This is the expected behavior on Windows 10.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The user will be prompted for administrative credentials via User Account Control.
Why this is correct
User Account Control (UAC) detects the attempt to write to protected areas and prompts for an administrator's credentials. If the user can provide them, the installation continues with elevated privileges. This is the standard behavior when a standard user tries to perform a task requiring admin rights on Windows 10.
- ✗
The installation will proceed but the application will run in a limited mode.
Why it's wrong here
Without administrative rights, the installer cannot write to protected system locations like Program Files or the registry, so it will not proceed successfully. Running in a limited mode is not an automatic fallback; the installation typically fails or prompts for credentials. This option misrepresents how Windows handles privilege requirements during installation.
- ✗
The application will install to the user's AppData folder automatically.
Why it's wrong here
Windows does not automatically redirect installations to AppData. Some applications may be designed to install per-user without admin rights, but this is not automatic and depends on the installer. The scenario states the application requires Program Files and registry changes, so it cannot silently redirect.
- ✗
The installation will complete but the application will be unable to launch.
Why it's wrong here
If the installer cannot write necessary files or registry entries, it will typically fail during installation rather than complete and then fail to launch. The lack of privileges blocks the installation process itself. This option incorrectly suggests that installation succeeds despite insufficient permissions.
