+// ToneShell Backdoor initializes data and dynamically allocates memory for a function pointer (PROPENUMPROCEXW), using it to enumerate window properties. It includes functions for dummy data handling, debug message output, and simulating file archiving with a password (without actual implementation). Key operations include:
+
+// 1.Data Handling: Obtains and processes dummy data.
+// 2.Memory Management: Allocates memory for executing function pointers.
+// 3.Window Enumeration: Uses EnumPropsExW() to list window properties.
+// 4.Debugging: Outputs static messages for diagnostics.
