WININET_E_SHUTDOWN
WININET_E_SHUTDOWN is a WinINet HRESULT. It means that the application attempted to use WinINet after its infrastructure was being shut down or after the required top-level handle had been closed. It is usually a lifetime or shutdown-order error in the application.
What to check
- Stop new network work before closing the top-level WinINet session and wait for owned requests to finish or be cancelled.
- Protect background callbacks and worker threads from using handles after their owner begins shutdown.
- Review teardown paths for races between handle closure and asynchronous completion.
