Windows Process : Tool to see Function and change arguments-Collection of common programming errors

Another useful tool is DebugView from SysInternals / Microsoft. Also, Process Monitor is pretty useful for seeing how other APIs work when interacting with them. Additionally, Process Hacker is a great runtime tool for inspecting memory regions, threads, DLL hooks, and so on. You can even modify the bits of memory if you wish, a bit like POKEs on the C64.
