Reversion to IE 10 and autocomplete

I installed IE 11, but found I had to uninstall IE 11 and go back to IE 10.  This was due to IE 11 being a problem when I was using the IBM Hardware Management Console on my laptop.  Since going back to IE 10, I have lost every ID that I had entered as far as entering the first few letters of a userid and having the system offer up the rest to you.  Saved me a lot of time. 

What do I have to do to regain those uses?

Thanks,

Dave
