[TASKMGR]
debug.c:
- Don't hardcode the size of the string buffers.
- Only use KEY_QUERY_VALUE right to query the values inside a registry key.
- Fix size parameter value given to RegQueryValueEx.
- Use ZeroMemory instead of memset(..., 0, ...) (heh, we're in Win32 guys!)
- Close thread-and-process handles of the spawned debugger app.
