Windows XP has color management built in (I think it was actually added in 2000, to compete with Colorsync on Mac) so Windows is ICC aware. I believe that IE DOES honor profiles, but you're system has to be configured properly. I'm primarily a Mac user, so Microsoft may have screwed up color management in IE, though. I don't think that's the case, I think people just misunderstand how IE and color management work. I'll explain.
When a lot of programs save a JPEG file for web use, they convert the file to sRGB and don't save a profile. This is because for the longest time, sRGB was assumed to be the color space you used for web graphics and most computers didn't have color management capabilities built in. Without the OS having a CMM, the profile was just extra data that increased downloading time on a modem.
Both Windows and Mac now have CMM and we don't worry so much about a few K in data size, so embedding profiles should work fine, but a lot of programs still leave profiles out for the web, for the same reason they use the web-safe color pallette as the color picker: we've always done it this way (does anyone still use a 256-color monitor? Or Netscape?)
In the absence of a profile, IE should just display the image without correction, but what it probably does is assume the profile is sRGB and assign sRGB to the file. So in the case of DPP, things will work fine as long as sRGB is the correct choice. Since a lot of people have been trained to use sRGB for web work, this works a lot of the time. DPP has sRGB selected as working space and display space by default (this second choice is a mistake, the display space should be your monitor profile).
You may not even notice a problem if you switched your editing space over to Adobe RGB. Adobe RGB has a larger color gamut than sRGB, but it's primarily in reds where the former exceeds the latter. If your image were primarily green and blue, when you assign sRGB to an image that's supposed to be assigned Adobe RGB, you might not see much difference. If the image had a lot of reds that Adobe RGB can handle but sRGB can't, those colors will be clipped and you will see a change in your image.
Sorry, but I don't buy your explanations in the previous post.
And IE certainly does NOT honor color profiles. If it did, people here would not be complaining that their images which were shot, edited and saved with the Adobe RGB profile embedded looks so dull and bland when viewed on their PC web browser. Of course, Mac users using Safari wouldn't know what they were complaining about but those using IE for Mac or Firefox certainly would.
