Kaypo, welcome to the forum! I don't quite understand what's happened to your color space, but have you tried System Restore? It can correct a lot of mistakes, it's saved the day for me more than once. You should be able to restore to a recent date. Should you need further assistance, post back. There may be other answers.
Thanks catilley ...Unfortunately machine is a couple of days old and no backup. Running it now but just too late, to help here I'm afraid.
Thanks anyhow ...Kaypo
First of all you need to remove a color profile then change the default color profile for one of your devices then you need to change the system default color settings for a specific device for all users on the computer and then change your default rendering intent or color space default.
