Skip the one-click debloat scripts — half of them break Windows Update and none of them are auditable. The boring truth is that a fast Windows install is mostly about startup apps, storage health, and killing the right defaults, in that order.
- Startup apps: Task Manager → Startup — disable everything that isn't audio, GPU, or input drivers.
- Storage: verify the boot drive is the SSD you think it is, and that it isn't at 95% capacity.
- Power plan: laptops on 'Best performance' when plugged in; desktops leave balanced alone.
- Notifications and tips: off. They cost attention, not frames — attention matters more.
- Graphics: set your games to the dedicated GPU explicitly in Settings → Display → Graphics.
Everything above survives updates and reverts cleanly. That's the test any tweak should pass before it touches your daily machine: if you can't undo it from Settings, it doesn't belong in the checklist.
