Internet Explorer has recently stopped letting me login to varies web sites. I get a message that internet explorer cannot display this page. I use windows XP. Can you help me

XP only supports up to a certain version of Internet Explorer, I think it's IE9. Some websites will not support it. XP is no longer supported as you know. You could always try installing alternate browsers such as Firefox or Chrome.

I agree. I use Chrome. I keep Firefox on hand. Once in a while any browser doesn't work for a bit.

I HIGHLY recommend upgrading from XP to a newer O/S of your choosing. Its no longer supported and as such is very vulnerable to hacking and other exploits.
