Every time you start BRUTAL Optimizer, Windows shows a User Account Control (UAC) prompt asking for administrator permission. This isn't optional or cosmetic: the app's core job — tuning the registry, stopping and starting Windows services, changing power plans, and installing drivers — are all operations Windows simply refuses to perform from a normal, non-elevated program. Here's exactly what needs admin, why we don't ask for less, and how to skip the prompt at sign-in if you want.
BRUTAL Optimizer's real work happens in places Windows locks down for safety. Without elevation, these would all silently fail or be blocked outright:
HKEY_LOCAL_MACHINE) — the bulk of the optimization modules.powercfg.bcdedit.Some tools offer a crippled non-admin mode. BRUTAL Optimizer deliberately doesn't, because almost nothing it does would actually function — you'd get a UI full of buttons that quietly do nothing. The app is marked requireAdministrator in its manifest, so Windows always prompts up front rather than letting it start in a broken half-state. If you click No on the UAC prompt, the app won't launch at all — that's by design.
If the per-launch prompt is annoying, you can have the app start automatically and elevated at sign-in — with no prompt — using its built-in startup option:
This is the only reliable way to skip the prompt. The old approach of a Run-key shortcut doesn't work for an admin-required app — Windows silently skips elevation-requiring programs placed there — which is why the app uses a scheduled task instead.
If you double-click the app and nothing happens — no prompt, no window — something is suppressing elevation:
Is it safe to give this app administrator rights?
Admin is required for any tool that changes Windows the way an optimizer does — registry, services, power, drivers. BRUTAL Optimizer backs up the original state of every reversible change and gives you per-module Undo plus Restore Defaults, so every elevated change can be rolled back.
Can I run it without admin, even with fewer features?
No. Nearly every feature touches machine-wide settings Windows blocks for non-elevated apps, so a no-admin mode would be a wall of buttons that silently do nothing. The app requires elevation up front instead of failing quietly.
How do I stop the UAC prompt appearing on every launch?
Turn on "Start with Windows" in Settings. It registers a scheduled task that launches the app elevated at sign-in with no UAC prompt — the only reliable way to skip it for an admin-required app.
Why didn't anything happen when I launched it — no prompt, no window?
Something is blocking elevation: you may not be on an admin account, UAC may be set to "Never notify," or antivirus/IT policy is blocking it. Right-click the shortcut and choose Run as administrator, and check those settings.
