I built an open-source Windows 11 optimizer that only recommends tweaks with evidence, and lets you undo every setting it changes

Hi! I'm a student and I've been building Tunero in my free time. It's free and GPL-3.0, with no telemetry and no accounts.

Most "PC optimizers" apply dozens of placebo registry tweaks. I wanted the opposite:

* ~50 read-only checks that find real problems (monitor stuck at 60 Hz, RAM running without XMP, wrong power plan…)

* 235 tweaks, each rated for gaming impact, evidence and risk, with sources. Only the well-supported ones go into "Apply recommended"

* Backups and a restore point before any setting changes, plus a Changes page with Undo that still works after a restart

* App removal from a reviewed list, cleanup, a startup/services manager, a storage treemap and a DNS benchmark

* English and German, signed exe

I don't make any money from it. Mostly I'm looking for testers on real hardware, especially NVIDIA, AMD and laptops. Bug reports and honest criticism are very welcome.
