    Type: REG_SZ
    Data: SunAwtDialog;javax.swing.JFrame;SunAwtWindow

    On 64-bit Windows:

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\CtxHook\AppInit_DLLs\Multiple Monitor Hook
    Name: javaw.exe
    Type: REG_DWORD
    Data: 24D7FF

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\CtxHook\AppInit_DLLs\Multiple Monitor Hook
    Name: javaws.exe
    Type: REG_DWORD
    Data: 24D7FF

    Name: <application name>
    Type: REG_DWORD
    Data: 84D7FF
