OK that's a pity, if they had an option which assumed that non-embedded images 
were sRGB (g2.2) then you could run your display profile at 1.8 and still have 
99% of graphics rendering as intended (idiots who write files using non-sRGB 
colour spaces and don't embed deserve the flack).

In the current Windows system it appears that colour management is implemented 
in a different way. The monitor colour space is associated with the monitor 
device, most CS aware apps (such as PS & ThumbsPlus) allow a default working 
colour space to be specified, however the monitor space doesn't affect print 
output so long as you are visually editing using the colour space of the print 
device as the proof view.

IOW I can run a g1.8 desk-top (monitor profile) and still edit in an sRGB work-
space and output for print with the full expectation that my prints will come 
back from the bureau looking like they did in my proof work-space (so long as 
they are converted before output to the printers specified work-space). The 
monitor profile just tells the apps how the monitor will behave in effect, it 
doesn't change file rendering as such.
