Zorluk: OrtaWindows Security Settings and User Account Control

A desktop support technician is configuring a Windows 11 workstation for an employee who uses screen-magnification software. When User Account Control (UAC) prompts appear, the desktop dims onto the Secure Desktop, causing the screen-magnification tool to temporarily stop rendering. Which of the following UAC configuration adjustments should the technician make to resolve the display issue while preserving elevation notifications?

  1. Set the UAC level to 'Notify me only when apps try to make changes to my computer (do not dim my desktop)'Cevap
  2. B
    Grant Full Control NTFS permissions on the system drive to the employee's user account
  3. C
    Configure Application Installation Permissions in Windows Settings to allow unverified app execution
  4. D
    Open Credential Manager in Control Panel and clear all cached administrative credentials

Cevap

Set the UAC level to 'Notify me only when apps try to make changes to my computer (do not dim my desktop)'
Setting UAC to notify without dimming the desktop prevents Windows from switching to the isolated Secure Desktop environment. This allows screen magnification tools and other accessibility utilities to continue rendering while still informing the user of pending application modifications.

Adım Adım Çözüm

1
Identify the cause of the screen reader/magnifier freezing during UAC prompts.
The issue is caused by UAC switching execution context to the Secure Desktop, which dims the background and temporarily disables third-party accessibility tools running in the standard user desktop context.
Secure Desktop isolates UAC dialog boxes to prevent malware spoofing, but this isolation breaks some legacy accessibility overlays.
2
Select the appropriate UAC setting to disable Secure Desktop dimming without disabling UAC completely.
Changing the slider to 'Notify me only when apps try to make changes to my computer (do not dim my desktop)' keeps prompt notifications active while displaying them directly on the interactive desktop.
This configuration allows accessibility tools to maintain visibility and focus while still requiring user confirmation for administrative modifications.
