Software & Games
Security and diagnostic tools, shipped as signed Windows installers tied to single-use license keys — each one yours alone, and revocable. Plus the free browser games, no install required.
Paste the key from your license email, then verify. Your download begins automatically.
Downloads are served over a single-use, 2-minute link. Keys are checked on our servers every time — revoked keys stop working immediately.
