Internet Explorer in XP

Can I remove IE in XP through remove windows components or it is a required & important component?

OK I removed IE, MSN, Windows Medial Player & MSN Messenger through Remove Windows Component.

But I cannot remove the folders of windows media player & IE from program files. It says in use. Tried restarting & disabling windows media player plugin in Dragon the only browser I use but no success.

How can I remove IE & WMP folders from program files? No other user accounts.
