# Atonsio
**enberda filipas con esta mierda**, eh. Increible que esto lo haya hecho alguien digno de ser big techie.
**Small prototype showing how to register as a COM application and reaching endpoint and session manipulation**.
Anyway, al caso:

# Notes
- Name might appear blank. This is not a bug, but rather an inconvenience due to the fact that many programs create unnamed sessions. Mixers, such as `SndVol` or mine, overcome this fact by fetching its parent process' name.
# Build
