Command line
Run this in an elevated PowerShell window. It fetches the same release, verifies its SHA-256 against the published checksum, and only then launches the installer.
Windows PowerShell — Administrator
$env:OPTIMAL_GITHUB_REPOSITORY = 'unquerys/Optimal'
& ([scriptblock]::Create((irm 'https://raw.githubusercontent.com/unquerys/Optimal/main/install.ps1')))Verify what you downloaded
Run this in the folder you downloaded to. The output must match the hash below character for character. If it does not, delete the file and download it again — do not run it.

Windows will warn you. Here is why.
The binaries are not code-signed yet, so SmartScreen shows "Windows protected your PC" on first run. A certificate costs money this project does not currently spend, and buying one would not make the file any more trustworthy than the checksum below already does. Verify the hash, then choose More info → Run anyway.
Before you download
Windows — Windows 10 version 2004 (build 19041) or newer, 64-bit. Windows 11 included.
Administrator — Required. Restore points, machine-level registry keys and power schemes cannot be written without it.
Disk — Roughly 150 MB installed, plus room for per-run registry backups.
Not needed — No .NET runtime, no account, no internet connection after the download — except for optional WinGet app installs.
What happens when you run it
It opens with nothing selected — Startup is read-only detection of your hardware and current settings. No change is staged, let alone applied.
You pick, then review — Onboarding suggests a plan from your hardware; you can ignore it and choose from the catalogue yourself. Either way you see the exact operations first.
A restore point comes before the first write — If Windows cannot create one, the run stops. Undo stays available from the History page afterwards.
