There are times when you might want to use different versions of SSMS, depending on the activity and the SQL instance version you are connecting to.
I stick the icon on my desktop, but by doing that, you have no indication of which version of SSMS the icon relates to, until you rename the text.
That works for identifying it when launching it, but what about if you have a 2008 SSMS and 2012 SSMS open, now you have the same icon on your task bar ...
So here are some new icons - click on them to download the ico file (rather than the png image shown below).
Once saved to your machine, right click on your current SSMS icons, choose properties, change icon, and there you go ... custom SSMS icons.
