I assume you are using IE7, (Internet Explorer V7), to check, open IE and goto Help > About Internet Explorer. As far as I know, only IE7 has the option to run without add-ons.
Which shortcut are you using to open this Internet Explorer? Is it the one in Start > All Programs > Accessories > System Tools > Internet Explorer, (No Add-ons)?
If so, that is what you get, IE without any add-ons. It is a diagnostic IE7 to allow you to see if any add-ons are causing IE any problems.
If you opened IE7 from a Desktop shortcut, then it should open normally, unless someone has switched shortcut icons, and placed an icon from the Start menu I said above onto your Desktop.
You can easily check that. The normal IE shortcut will have different Properties to the shortcut in the System Tools area of the Start menu. Right click the shortcut on the Desktop, and select Properties. If you just have 4 tabs, eg General, Shortcut, Compatibility, Security, then the shortcut has been switched. If it has the following tabs, it is the genuine one;
Tabs: General, Security, Privacy, Content, Connections, Programs, Advanced.
