Get Boost Opti

For Windows 10 and 11, 64-bit. The check is free and needs no account.

Installing it

1. Open the file you downloaded. Windows asks for permission, because the app is installed for everyone who uses the PC.
2. If Windows shows “Windows protected your PC”, choose More info, then Run anyway. The installer doesn’t carry a publisher certificate yet. The next section shows how to be sure of the file without one.
3. Open Boost Opti and press Run full check. Nothing is changed until you choose a fix.

Checking the file

Every release comes with a fingerprint of the installer, called a SHA-256 checksum. To compare it with the file you downloaded, open PowerShell in your Downloads folder and run:

(Get-FileHash "Boost-Opti-Setup-1.0.0.exe" -Algorithm SHA256).Hash

If the answer matches the checksum shown with the download, the file is the one we published. If it doesn’t, delete the file and tell us.

Removing it

In Windows, open Settings, then Apps, then Installed apps, find Boost Opti and choose Uninstall.

Uninstalling doesn’t reverse the changes the app made. If you want any of them put back, do that first: open History in the app and press Undo everything.

Your settings and history are kept in %APPDATA%\Boost Opti. Delete that folder to remove them as well.
