taskmon.exe - The Task Monitor checks the disk-access patterns of programs when they are started and stores this information in log files in the Applog folder. Task Monitor also records the number of times you use a program. The Disk Defragmenter tool uses this information to optimize your hard disk so that programs that you use frequently are loaded faster. Not required - but can be useful. Note: for Norton Anti-Virus 2002 users, loading TaskMonitor will typically solve many, if not most, of those annoying IE scripting errors (per Symantec's Knowledgebase)
