When I updated to Windows 8.1 it made my windows gallery color profile off and everything is yellow.  I am a photographer and use windows viewer for a quick look at pictures.  Everything is dark yellow.  I am afraid to do anything that will make my color profile off in my pictures that are saved, or lose information.  I use i1profiler to calibrate my computer, but don't know what calibrating on the drive will do to everything.  Ahhhh, if Microsoft knows that there are this many problems with the update, there should be a warning before asking to update.  So frustrated.
