You'd think that this would be fairly easy considering the company that makes the IDE also makes the operating system. Unfortunately not.
As I (and others) have discovered there are times when you'll need to manually download and install sub-components from the Microsoft Download Centre (http://www.microsoft.com/download/en/default.aspx) because the installer is unable to do so by itself if there happens to be a problem with the ISO that you have downloaded.
Funnily enough, based on research into other people's problems, manual extraction and installation from the subsequent file has been a constant theme. Complete re-installs (of Windows) have been mentioned as well as removals and re-installs of some components.
Download problems seem to occur on a particularly regular basis with their http://www.dreamspark.com website. It seems the VS2010 download seems to have continual problems when being downloaded as a single whole file. Funny thing is that while the actual Microsoft website has the option to download as seperate large files that are later combined they don't seem to offer this option on the http://www.dreamspark.com website. Just like Windows 7 though there seems to be some evidence to suggest that it may be possible to convert from one version to another (including trial versions) using minimal modification of key files.
All this being said, once installed the program is actually quite good. On an mid-spec i3 laptop it was perfectly responsive and quite functional.
