Recommendation

Keep enabled

Keep the consent prompt for third-party applications and show it on the secure desktop.

A disabled prompt allows an administrative action without confirmation. This can skip an unnecessary prompt, but protection weakens. A game does not get faster from this.

Prompt: for third-party programs
Desktop: Secure desktop
Performance: No benefit from disabling

In short

UAC runs ordinary applications with standard user rights and requests consent when administrator rights are needed. The secure desktop isolates the elevation prompt from ordinary windows.

The BoosterX setting removes the secure desktop and allows administrators to elevate without a prompt. It does not fully disable UAC via EnableLUA. This does not affect FPS during normal gameplay: the prompt appears only on elevation.

Registry changes

Path	Name	Recommended	Weakened state
`HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System`	`PromptOnSecureDesktop`	`REG_DWORD 1`	`REG_DWORD 0`
same	`ConsentPromptBehaviorAdmin`	`REG_DWORD 5`	`REG_DWORD 0`

The value 5 means a consent prompt for programs that are not part of Windows. The value 0 means elevation without a prompt.

How to change and revert

In BoosterX, open “Optimization” → “Security” → “Hardening (VBS/UAC)” → “UAC” and move the toggle to “Off”: BoosterX will apply the standard Windows values with UAC prompts. Click “Apply” at the bottom of the page. If “Instant apply” is enabled, the change is applied immediately. To weaken protection, the “On” position is used: BoosterX will apply its recommended disabling of consent prompts and the secure desktop; standard Windows protection is restored by the “Off” position. After applying, check that an unknown program launched as administrator triggers a visible prompt on the dimmed secure desktop.

Sources and verification boundaries

This page covers the two specified Windows 11 policies. On Windows 10, the same card additionally disables the UAC file virtualization service (luafv). Other UAC policies and domain management can change the resulting behavior.
