I am setting up a new virtual machine with Windows 7 and installed all updates.  I installed Visual Studio 2010 in about an hour, and followed up by adding on ASP.NET MVC 3 install.  My next task was to install SP1, which has taken 4 hours to install.  Most of the slowness was the download because I recently moved and we signed up for the basic internet package (up to 1 MBPS download) for now.  But by doing so, turned into what was expected to be a 45 minute install into a 4 hour install.  I was hoping it to be faster, but that’s what you get when you go for the basic DSL package 🙂  In the past, I had a faster package and did not experience this time lag.

I thought it might have been an issue with this: http://blogs.msdn.com/b/heaths/archive/2011/03/02/visual-studio-2010-service-pack-1-installing-for-over-2-hours-could-be-a-sign-of-a-problem.aspx  However, I followed the steps (had to copy the .tmp.html and paste it in the folder to read it because the file was locked), and the WM_ACTIVATEAPP line that blog mentions was not present.  So the issue for me was completely download speed.

Just passing this on in case it may help someone to make a determination.
