Auto-complete

[#1]

Is it possible to persuade XP to add, modify and remove specific auto-complete data?
Examples:
1. I once tried to log onto the main Plusnet site with a username which I use elsewhere which is my Plusnet username with a few extra characters on the end. Now every time I log on, auto-complete prompts that longer username and not the correct one.
2. There are one or two sites where I've been asked in the past whether I want Windows to remember my entries in certain fields, and I've said no at the time but now wish to change my mind. Is it possible to do so?
3. In IE7 I have a few typos of URLs which are offered ahead of the correct ones - can they be removed?

Thanks,
Steve

PC Magazine had a free utility a while ago to manage your autocomplete list, I still use it.

Removing items from the auto complete drop downs is easy. Start keying so the list appears, cursor down to the item you don't want and then hit delete.
