Possible Security Breaches w/DOS and Windows

IN WINDOWS...

My Computer->C:->Windows->System->msconfig
Use msconfig to change startup files (useful for school networks, disable any monitering software/blocking software that are running at startup must restart!)

My Computer->C:->Windows->command.com
Explination to come

IN DOS (Command.com)

fdisk-See above. Very quick and destructive. Create new partition and set to active for best results. (It covers your tracks since it will say it will need a boot disk, and no one will firgure it out since a boot disk doesn't do anything) All data is then lost and unrecoverable.

format-See above. Slow and stupid. For the neurally challenged individual.

deltree c:\windows -Say yes to everything=complete destruction.

del c:\*.* -desturctive

FINALLY...THE MOST DESTRUCTIVE AND INRECOVERABLE
Take a sledgehammer and jackhammer, or even better, explosives, and blow the computer up. The only disadvantiage is that it makes a heck lot of noise and is very obvious. (Not good for stealth operations)
