bash / fuck-ms-teams

An AppInit DLL that stops Microsoft Teams from hijacking the play/pause button.

Fuck MS Teams

Microsoft Teams hijacks the play/pause media key after playing the ringtone. This project prevents Teams from registering for the play/pause media key with Windows and ruining everyone's day.

Installation

Build the library using:

cmake -B build
cmake --build build --config Release

Register the library as AppInit DLL in your registry:

• Set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\RequireSignedAppInit_DLLs = 0 (dword)
• Set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\LoadAppInit_DLLs = 1 (dword)
• Add <PROJECT_DIR>\build\Release\fuck-ms-teams.dll to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs (string)

FAQ

How does it work?

Windows provides a mechanism called «AppInit DLLs» for injecting custom code into every process. Using this mechanism and the amazing MinHook library we can inject code into Teams.exe that patches the RegisterHotKey function.

Is it safe?

Most likely not. Use at your own risk.
