Yes Windows in all it's variations has had either full blown or partial colour management since W98. This however doesn't mean that all your applications are colour space aware. They may and most do totally disregard the colour management system so render colours to the screen device in its native colour space in a linear fashion (ie without management). > However to support my contention that SFW converts to sRGB I saved an > Adobe98 16bit .psd image, both pre-converted to 8bit sRGB and without > any manual conversion, via SFW.

The SFW option doesn't convert colour spaces, it will strip embedded profiles therefore leaving the image without colour space references for the application that will consequently be used to open the files. With non-CS aware applications the accuracy of the screen rendering hinges solely upon the setting of the display, it may or may not be even close to sRGB and I'll contend that any screen who's whites look even remotely blue is way out of sRGB spec. To give you an idea of how stuffed up the whole system can be without active colour management my top end pro CRT monitor shipped with one colour profile which was for a 9300k white-point, that's so far away from sRGB it's not funny. The unit also has a sRGB mode which pre-sets color temp white-point and black- point (the user has no access to contrast of brightness controls they are preset) however when actually measured it's in error by a significant margin relative to the standard. Also I tested my XP Pro box with the latest IE6 and Firefox 1.5 last night and neither are remotely colour space aware.
