I’ve done something and stopped my machine remembering my login and password details to web sites like this. Been to ‘Local Security Settings’, IE7 security settings etc. and can’t find how to reset it.

Help for the brain dead welcomed.

Answer for any and all problems with IE: Firefox

It's better, it's safer, it's faster, it remembers your password, it has clear and simple preferences (rather having settings spread around the entire system). It will import your bookmarks on install so you really don't have to do anything but download it.
