You can also try Browzar which is currently at the centre of some controversy - and don't rely on it for complete anonymity, there really is no such thing. However this lightweight program that sits on top of Internet Explorer does away with auto complete, browsing history and cookies, so that no trace of what you've been up to is left behind.

The internet files are deleted not wiped, so recovery software could still track where you've been, and a list of browsed sites remains in index.dat, but that's really beyond the scope of the program. You can stick the program on a usb key and quickly install it on a shared computer.
