Disable Plug-ins

If
IE runs too slowly, or if it freezes up on you a lot, try disabling
some of its preinstalled add-ons. Click Tools > Manage Add-ons >
Enable or Disable Add-ons to see which add-ons are enabled. Select an
add-on you don't want preinstalled, then click the Disable radio button
under Settings to deactivate it.
Open Multiple Web Sites
Want IE to open two or more tabs when you start it up? Go to Tools >
Internet Options, then type as many addresses as you want (on
individual lines) in the "Home page" field.
Change Text Size
Hold the Ctrl key and roll the mouse wheel to change Web pages' text
size: Rolling up makes it smaller, rolling down makes it bigger.
