During the beta phase, there was a law suit either threatened, or actioned, towards MS, by other browser makers. This was particularly in Europe. As a result, European editions, and maybe now others, came with the popup option to install IE8, which should have been the default and installed automatically.
There are one or two ways to stop it. This is my preference.
Open (Type in the start) gpedit.msc.
Click on User Configuration, Administrative Templates, Windows Components, - Internet Explorer.
Rght click on Prevent performance of First Run Customize settings and then click on Edit. - Click "enabled "and OK.
