What UAC-related issue occurs when using Pupy's screen control, and how can it be mitigated?

When operating with standard user permissions, Pupy cannot interact with UAC pop-ups because the consent.exe process requires system privileges to close. To disable UAC prompts temporarily, you can use the registry command `reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v ConsentPromptBehaviorAdmin /t REG_DWORD /d 0 /f`, and re-enable with value 5.
