What are the two open-source implementation methods mentioned for deleting logs after obtaining the handle?

The first method involves parsing the EVTX format directly and implementing custom log deletion logic. The second method uses the WinAPI `EvtExportLog` to filter out log entries to be deleted, then overwrites the system logs with the filtered content. Both methods typically require suspending the logging thread first to prevent new entries from interfering. The complete open-source code is referenced in Windows XML Event Log (EVTX) Single Log Entry Deletion (Part 5).
