It seems like the windows version of Krita doesn't look for color profiles in "C:\Windows\System32\spool\drivers\color", this means it cannot autodetect pre-installed color profiles which is slightly problematic I know that on Linux it does auto detect pre-installed color profiles, so it should do this on Windows too.

Please fix this.

Also while I'm at it, the remove scrollbar option under the display menu in preferences is not present in the windows version, any chance we can get that over there too?

Please report the first issue at bugs.kde.org. The second issue is a problem with graphics drivers on Windows together with Qt's OpenGL widget. I think we can try to revisit that issue once we port to Qt5, but not earlier.
