This (http://www.microsoft.com/downloads/details.aspx?FamilyId=1E33DCA0-7721-43CA-9174-7F8D429FBB9E&displaylang=en) sounds like it would be very handy (if I didn't already have another utility that did about the same thing).

Perhaps someone could try it and report back? Maybe with screenshots?

As a Windows User, I apparently already have this software, it seems to basically collect all your profiles and calibrations so you can switch on the fly. To my way of thinking, I have the adobe util, the epson util, the nvidia util all which manage calibration and calibration adjustments. Now co-ordinating each of the colourspaces and calibrations seems an art without another utility allowing custom calibrations
