Well, IE stuff certainly is rather ingrained in other things... When I had a problem with some DLL file, stopping me from running IE (encountered a problem), the same error popped up in Windows Live Messenger.
Aaand the first time this happened I kinda... tried to repair/reinstall IE, and I kinda... could only... find... IE7. (or maybe it was the IE6 one not working, I can't be sure). Oops. All worked after that though.
And I later found that a simple reinstall of Messenger solved the issue too, when the same thing happened again.
You cannot "go back" to IE 7.
I think you can - as detailed thus:
http://support.microsoft.com/kb/927177According to that, IE6 is restored when IE7 is uninstalled.
I never got IE7 in an automatic update - the big one I narrowly avoided was a "Windows Media update" - which I almost realised too late would be an upgrade from 10 to 11 (11 is NOT nice, very difficult to find anything... And I like my orange player)
Which is why I ask for a prompt before the computer even downloads any so-called "Automatic" updates.
