Intellisense in vs2010 with c++

Question

I can\'t get intellisense to work. Even if I start with an empty project and add just one file to it with only an include for iostream and an int main()

Answer 1

baruch's answer worked for me. for completion, here is also the link to the VS2010-SP1: http://www.microsoft.com/en-us/download/details.aspx?id=23691

so first installing this and then the hot-fix that baruch referred to solved me the problem, although the whole installation took almost 1:30 hour! (including one restart on my Win-XP machine.)
