Application / window casting requirements:

Windows 10.0.19041+ or Windows 11
The Windows capture template service (CaptureService) must be registered and allowed by privacy policy. CaptureServiceis a trigger-start, per-user service. A service instance named CaptureService_<random> is created on demand when an application calls GraphicsCaptureSession.StartCapture() in that user session.

To check if the template service is registered on your workstation (use elevated cmd): - sc qc CaptureService should return the following (START_TYPE = DEMAND_START):

    [SC] QueryServiceConfig SUCCESS
    
    SERVICE_NAME: CaptureService
              TYPE               : 60  USER_SHARE_PROCESS TEMPLATE
              START_TYPE         : 3   DEMAND_START
              ERROR_CONTROL      : 1   NORMAL
              BINARY_PATH_NAME   : C:\\Windows\\system32\\svchost.exe -k LocalService -p
              LOAD_ORDER_GROUP   :
              TAG                : 0
              DISPLAY_NAME       : CaptureService
              DEPENDENCIES       : RpcSs
              SERVICE_START_NAME : NT AUTHORITY\\LocalService
    
- `reg query HKLM\\SYSTEM\\CurrentControlSet\\Services\\CaptureService /v Start` should return:
    
    HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CaptureService
              Start    REG_DWORD    0x3
    
- `reg query HKLM\\SYSTEM\\CurrentControlSet\\Services\\CaptureService\\Parameters /v ServiceDll` should return:
    
    HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CaptureService\\Parameters
              ServiceDll    REG_EXPAND_SZ    %SystemRoot%\\System32\\CaptureService.dll
    

To test the template service on your workstation (use elevated cmd):

- `sc query type= service state= all | findstr /i capture` should return:
    
    SERVICE_NAME: CaptureService_<random>
    DISPLAY_NAME: CaptureService_<random>
