The drwtsn32 executable is the Dr. Watson utility, which Microsoft describes thusly:
"Dr. Watson detects information about system and program failures and records the information in a log file. In the event of a program error, Dr. Watson starts automatically. ...To open Dr. Watson, click Start, and then click Run. In the Open box, type drwtsn32. Dr. Watson cannot prevent errors from occurring, but the information recorded in the log file can be used by technical support personnel to diagnose the problem. For information about using Dr. Watson, click Help in Dr. Watson."
Once you enable it, the only way to disable it is to edit the registry:
