Want to enable a whole new level of security? Alot of software security programs modify some of the setting you can find by using this tweak.

Go to this registry directory

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings\Zones\0

And modify this:
"Flags"=dword: 0X00000001 (1)

It enables a 5th security zone. You'll have to reboot or logoff to apply this change. It'll lock down your system as much as windows possibly can! To see this go to IEoptions --> Security --> Zones
You'll find My computer..
