Overwolf

Overwolf.exe is Overwolf, a platform that hosts third-party in-game overlay apps: stat trackers, clip recorders like Outplayed, and mod managers like CurseForge. If you installed any of those, Overwolf is the engine under them. It draws app windows inside a game by injecting a Chromium-based layer into the game process.

What running it does to your system: Overwolf runs entirely in user mode with no kernel driver, but its helper processes perform user-mode injection into games to render overlays, a legitimate technique that security tools and anti-cheats still scrutinize. It installs an auto-starting updater service and launches at login, and each app spawns its own browser process. It reads the screen for clip capture and reads game events through its provider API. Its record shows both sides of the injection question: a 2021 Warzone wave falsely banned Overwolf users on Windows 11 Insider builds before Overwolf changed its injection method (Dexerto), while Riot has formally approved Overwolf for Valorant and League, with apps requiring approval to list. FACEIT's anti-cheat, by contrast, blocks Overwolf's game-event access in CS2, which disables its event-driven features.

The practical step: Overwolf is widely used and legitimate, but if you play under strict anti-cheat, check its game-compliance pages before relying on an overlay, since FACEIT blocks it and approval is per game. Because its injection helper is a known dual-use binary, if you find an Overwolf process and never installed it, confirm it is signed by Overwolf before trusting it.
